Product Discription
Series Double Drum Chain Grate Biomass Water Boiler
The series Double drum chain, grilled biomass hot water boiler, the main engine in the boiler is designed as a double drum length arrangement, the top drum is equipped with a steam separation device, the bottom drum is equipped with a waste water discharge device during the set period, and an oven Its left and right sides are equipped with water pipes.The electric grate is used to automatically add fuel, and the back of the grate is a drilling chamber and a convection tube. The fan and the induced traction frequency adjuster are distributed for mechanical ventilation and are equipped with an automatic charge charge. The fuel enters the chain stone and enters the furnace for combustion. The flue gas enters the tail stream through the furnace, embalming, convection pipes, economists or air heaters, enters dust moulds, induced traction, the chimney and finally is released into the atmosphere.
Product Features
1. Easy installation:
Boilers are generally fast -loading installations which are convenient for the transport and installation of installations, significantly shorten the installation cycle, save on installation costs and allow the use of boilers in time.
2. Reliable operation:
The heat surface of the boiler is reasonably aligned, the water circulation is smooth and the heat surfaces are cooled in time to ensure the safe operation of the boiler.
3. Easy maintenance:
The boiler drum is equipped with maintenance holes to repair it. It is convenient to open the smoke box in front of the oven, comfortable and ready for personnel inspection, which provides good conditions for proper treatment.
4. full burn.
Using secondary air and a sensible furnace design, the fuel can be fully incinerated and the black smoke can be removed.
5.High efficiency:
The bumper grate uses dual -sided ventilation and dust removal technology that makes the back of the grate naturally ventilated, avoids air leakage, oil cover and uneven ventilation, and is easy to operate. Compared to ordinary roast, it has obvious advantages.
6. removal of ashes:
Boilers may be equipped with several vacuum cleaners capable of removing ash in a timely and efficient manner, avoiding operational failures and thermal efficiency failures caused by ash chain accumulation and ensuring boiler stability.
