PRODUCT SPECIFICATIONS

Fly ash, furnace production of sintered porous brick, is the use of fly ash itself contains heat energy burning brick, melting furnace in the preheating, sintering, cooling three processes. Fly-ash perforated brick firing temperature is usually 900 ° C ~ 1000 ° C, after high temperature calcination, after the heat into the cooling section, the brick body temperature can still reach about 700 ° C, this time porous brick has been sintered, the transformation is basically completed crystal form . In the normal production process, the cooling zone has begun at around 700 ° C, and the perforated bricks entering the cooling zone carry a large amount of heat, which is radiated to the top of the kiln, kiln walls, kiln cars and combustion air by means of heat radiation and convection Transmission, resulting in kiln body, kiln car and porous brick itself more than partial heat, eventually distributed to the atmosphere, causing great waste. Melting kiln production is continuous, the ambient temperature in each section of the cooling section is relatively stable, the heat source clean and free of dust, which provides a stable source of heat for the utilization of waste heat.
Set in the melting kiln waste heat boiler, it is necessary to maintain a reasonable melting curve, but also generate enough steam to meet production and life needs. To make the waste heat boiler can not affect the quality of the sintering of the brick, but also generate enough steam requirements, the boiler is generally installed in the front of the melting zone is more favorable because of this interval, the residual moisture of the brick has been ruled out, internal body energy Outbreak, the boiler absorbs part of the heat from here and does not affect the melting; In addition, if the body heat is high, the boiler can absorb a lot of heat from here to prevent high temperature and cooling section temperature is too high to solve the problem of super-hot-melt . However, for sulfur-containing raw materials, there is still a large amount of sulfur dioxide gas in the front end of the melting zone, which will inevitably corrode the equipment. Therefore, it may be considered that the boiler is set in the region of about 800 DEG C after the thermal insulation section of the burning furnace at this time.
Waste heat use
Brick factory, milling, board factory area, living area in winter heating (steam warm), staff exchange hot water throughout the year; wash water for production exchange;
