Starting from what choose steam boiler?

Steam boiler evaporation
Optional steam boilers, steam boilers first look evaporation, evaporation should be close to the rated boiler you produce the maximum amount of steam or heat. Production of steam boiler is about 80% of the rated evaporation is more appropriate, because the pipeline losses, boiler scale, soot and other issues will make the boiler is impossib

le to achieve the best operating condition. Drew particular attention is that China's boiler evaporation is nameplate (nominal) evaporation under pressure, while some foreign boiler which evaporation is zero pressure evaporation, the actual boiler output vary greatly. Example: My 1.25Mpa, 4t / h boiler of its output is produced four tons per hour of steam 1930C, while some foreign furnaces produce 4 tons per hour of steam 1000C.
Steam boiler feed water temperature
Evaporation nameplate on the market the same boiler feedwater temperature of its 20 ℃, 60 ℃, 90 ℃, 100 ℃, 105 ℃ five kinds. The same boiler plate evaporation due to the high and low water temperature, the actual evaporation boiler will have a greater difference. For example: 20 ℃ water temperature of the boiler's output and the output water temperature 100 ℃, there are quite different. 20 ℃ water temperature of the boiler's output is 100 ℃, the output water temperature is 114%. Small capacity boilers are generally used at room temperature water, how you will feed water temperature to 90 ℃ or 100 ℃ before entering the boiler do? (Except thermal oxygen required)
Steam boiler working pressure
Boiler plate should be greater than the rated steam pressure steam supply pipe resistance and produce the desired working pressure combined. Please do not ignore the steam pipe resistance, due to its higher rated steam pressure saturated steam temperature is higher.
Steam boiler heating surface
Compare boiler heating surface (heat transfer area) is to choose a major boiler (design) parameters. Because the boiler heating area generally large output, overload ability, on the contrary, contribute to the small. Boiler capacity is the same, relatively large heating area, the exhaust gas temperature is relatively low, the boiler efficiency is relatively high, the heat generated by burning fuel more fully utilized, low fuel consumption.

The important role of steam curing autoclave

Autoclave steam curing fly ash aerated concrete is a necessary condition to obtain strength. By heating, thermostats, cooling and other heat transfer operations, but in the heat content of the water when it does not completely evaporate, vacuum extraction makes aerated block thermal conductivity decreased. In the steam autoclave curing conditions, aerated concrete between the constituent materials in a series of physical and chemical reactions and the generation of the aerated concrete hydration products become different from the original body of the new artificial stone. In the steam autoclave curing process, aerated concrete body will withstand the temperature and humidity changes, resulting withstand various impacts. Autoclave curing process task is to use the autoclave curing autoclave aerated concrete hot and humid conditions inside the hydrothermal reaction sufficiently, so that it has the required quality. At the same time, but also effectively prevent the autoclave curing process may occur is not conducive to the hydrothermal reaction or detrimental effect on the curing conditions and the quality of product. Conservation products must have a certain way, otherwise it will cause some damage products: provide good heat carrier; create a good heat exchange environment; appropriate heating rate; sufficient temperature and time; reasonably cool; body with the necessary strength and temperature as high as possible. And these conditions by saturated steam pressure, vacuum extraction, heating, thermostats, cooling and a series of steps to determine.

What are the advantages of autoclave steam curing piles

what became the darling of the industry?

Why Materials reforms implemented? Vintage brick wall materials mainly refers to the sintering led building materials, sintered clay brick production consumes a solid clay brick clay 3 kg per 100 square meters of building area, about 10,000 bricks. Every 10,000 square meters of construction, the use of solid clay brick require excavators 3000 tons. China's cultivated land area accounts for only 10% of the land area stronger, less than half of the world average. China Housing 70% of building materials wall materials, including clay dominate the production of clay bricks annually consume resources amounted to over 10 billion cubic meters, equivalent to destroying the 50 acres, at the same time, China's annual production of clay bricks consumption of more than 7000 tons of standard coal. If the solid clay brick production continues to grow, not only increases the production of wall materials, energy consumption, but also leads to new buildings heating and air conditioning energy consumption increased significantly, it will seriously aggravate the energy supply and demand. Refers to a new wall material energy, land, waste utilization, high strength, seismic, environmental protection and other properties of the wall material. Autoclavedaerated concrete block is a kind of fly ash and sand aerated by the two main raw material, and then with cement, aluminum, lime and other raw materials, rust, corrosion, high temperature, high pressure, steam curing processes such into porous concrete products, it can float on water, bulk density generally 300-800kg/m3, only solid clay 1/4, hollow block, 1/2, reduce the load of 50% of the wall - 60% construction to reduce weight 20% - 30%, construction speed, greatly reduce labor intensity and construction cost. It has significant thermal insulation properties, can reduce building energy consumption. Its thermal conductivity is 0.168w/mk, thermal insulation effe

ct is four times the clay is hollow block three times, cool, greatly reducing the air conditioning running time, saving power consumption 30% - 50%, is to achieve architectural energy-saving wall material of choice. Aerated concrete block trends more than a wave of a strong wave of these words to describe. The new wall materials on board soon after the building materials market has achieved the status of clay bricks, became the new darling of construction materials, and environmentally friendly energy, recycling, etc. have been recognized by the majority of builders, and we welcome people, industry prospects natural Needless to say. This has resulted in aerated concrete block production line suppliers increases, which has a lot of fish in the enterprise, if the customer wants to invest must be very cautious.

Why need aerated autoclaved concrete block

Aerated concrete has been widely used in the modern production , aerated concrete block usage also increased substantially. why aerated concrete block in the production process should through high-pressure steam curing, What are the benefits for autoclaved aerated concrete blocks? Here to introduce you to autoclaved aerated concrete block had many advantages.
Lightweight
Aerated cement block normal weight of 500-700 kg / cubic meters, only the equivalent of bricks and sand-lime brick 1/4-1/3, usually cement 1/5, is a mild form of cement , suitable for use in the construction of high-rise and low-rise construction of additional walls load-bearing walls. Using this material, so that the whole child build self-respect than usual brick structure built to reduce the weight of more than 40%. Because weight construction slowed, earthquake damage is small, so increased seismic archway experience greatly.
Good thermal insulation properties
Ordinary thermal conductivity of 0.11-0.18 kcal / m 0 hours 0 degrees, only grains of sand-lime brick and adobe 1/4-1/5 (tablets adobe thermal conductivity coefficient of 0.4-0.58 kcal / m 0 hour 0 degrees; sand-lime brick thermal conductivity coefficient of 0.528 kcal / m 0 hours 0 degrees), as usual cement about 1/6.
High strength
Thought experiment, aerated cement block compressive strength greater than 25 kg / cm, equivalent to 125 bricks and sand-lime brick compressive strength.
Seismic performance
In the earthquake of Tangshan Feng level 7.8 earthquake in the South and other places, according to post-earthquake inspection, aerated concrete construction revealed only a few new fissures, while full-brick structure built almost all collapsed, so that the two apart is not far as the same structure and the construction material is not formed bright contrast. Parse think that this is because of aerated cement light density, performance groups, earthquake inertia force is small, so have some experience earthquake. This is our country in terms of this multi-earthquake would be a very big benefit.
Processing performance
Aerated concrete has better processing performance. Can saw, to dig, to nails, to milling, to drill. Moreover,  in the production process and reinforced. To start  bringing great convenience and flexibility.
Have a certain temperature resistance
Aerated cement at a temperature below 600 ℃, its compressive strength increased slightly, when the temperature at about 600 ℃, its compressive strength is close to normal temperature, so as a foam cement fire performance of aerated concrete achieve a national fire safety standards.
Noise performance
Gas from aerated concrete eye structure known as aerated cement inside the structure like flour and water fermented foods Similarly, the number of strokes and more evenly distribute gas eyes closed, because this is an ordinary foam cement do not have the acoustic performance .
Helpful for mechanized start
Until now, the things on the situation, precast aerated concrete slab can save the finished assembly stacking space; saving masonry labor; detract wet work; accelerated by the presence of start into the extent of the rate increase to start.
Fit and strong
Can be based on local raw materials is not the same, not the same conditions tailor-made. Raw materials can be selected river sand, fly ash, ores and other kinds of remedy. Moreover, can be salvaged, helpful environment, the real turning waste into treasure. Aerated cement facility made out of aerated cement block, the strength values ​​are relative to certain conditions in terms of water content, called the reference moisture content, moisture content and the intensity of the reference range countries vary exactly the same.
Aerated concrete block can not be compared with a traditional clay brick numerous advantages, but also environmentally friendly, reduce waste dumps, useful for the urban environment, therefore, aerated concrete block is to promote the government's construction materials. With the acceleration of urbanization, aerated concrete market will promising.

Prospects for biomass boilers

As society's growing demand for energy as the primary energy source of fossil fuels has rapidly decreased. Therefore, finding a renewable alternative energy sources has become the focus of society in general. Biomass energy is an ideal renewable energy, it is wide variety of sources, every year a large number of industrial, agricultural and forest waste generation.
In the current world energy consumption, biomass consumption accounted for 14% of total world energy consumption, second only to oil, coal and natural gas, ranking fourth. In developing countries, biomass energy sources account for a large proportion of more than 50%. According to statistics, the global biomass accounted for 35% of renewable energy resources, renewable resources, top. In our country, especially in northern areas corn stalks, rice husk and other renewable southern resources are very rich, with its replace or partially replace coal, not only for enterprises to bring huge economic returns, but also increase the income of farmers. Of biomass production (mostly straw)

of about 750 million tons, while the annual use of less than 30%, indicating that the use of biomass energy is still great potential.
Biomass is a clean and renewable energy, CO2 emissions close to zero, so the use of biomass for the protection of the environment, improve the ecological, improving their living standards and so has an important role. Biomass fuel directly as a boiler fuel, but also  the use of biomass in an effective way. Biomass fuels with fossil fuels, has the following advantages: 1, renewable; 2, low pollution: SO_X, 、NO_X emission concentration is low; 3, biomass as fuel in the growth cycle, the net carbon dioxide to the atmosphere approximately zero emissions, which can effectively reduce the greenhouse effect.
In recent years, biomass boilers in China has been rapid development. Along with the environmental protection requirements, biomass boilers as a waste recycling environmental protection boiler will usher in the peak period of development. Meanwhile, the many advantages of biomass fuels has become a fast-growing biomass boilers reason.
