6t 6000kg Low Running Cost Manual Type Coal Fired Steam Boiler For Plywood Hot Press Machine
Water-cooled walls are arranged on both sides of the biomass boiler to form the furnace and convection flue, and the single-pass threaded smoke pipe is arranged in the barrel, which has a larger combustion space and sufficient height, so that the fuel has sufficient burning time in the furnace. Cast iron economizer. The front and rear arches of the furnace are water-cooled and cast integrally. The front arch is stepped and the back arch is herringbone, which makes the coverage of the arch close to 85%, which is conducive to the burning of bituminous coal. A large block chain grate is used to achieve mechanical combustion. Equipped with an induced draft fan for mechanical ventilation, sufficient secondary air is arranged in layers at a certain height in the furnace, and equipped with a slag discharger to realize mechanical slag discharge, complete control and monitoring instruments.
Boiler steam pressure automatic adjustment system: The control system of the boiler steam pressure automatic adjustment system enters the working state. When the necessary conditions for combustion are met: the steam pressure in the boiler is higher than or equal to the set pressure upper limit, the control system outputs a stop signal. Until the induced draft fan is stopped.
Water supply automatic control: When the system is on duty and in normal operation, the water supply pump is started, and the water level differential pressure transmitter detects the water level signal to keep the water level of the drum stable. Ensure the quality of steam. The water level adjustment instrument displays the boiler water level.
Manual control: You can also manually control the water pump, etc. through the manual touch key on the control panel.

Boiler feature
1,Horizontal,3 pass and large furnace
Ensure the sufficient combustion.
The large diameter boiler increase the heating surface to ensure the high thermal efficiency.
2,The spirally corrugated tube
Strength the heat transfer and improve the thermal efficiency .The smoke in the tube has the distribution effect,the dust not easy to deposit ,the tube can cleat by itself.
3,High temperature resistance refractory brick
The furnace wall is poured by the heat resistance concrete and high temperature resistance refractory brick,decrease heat loss,increase the boiler thermal efficiency.
4,The economizer
Made of ND corrosion resistance steel,make full use of gas heat .reduce the exhaust temperature improve thermal efficiency.
Coal fired steam boiler is widely used in hospitals, schools, textile mills, garment factories, large supermarket, garment factories, dyeing factory, hotel, dining room, restaurant, food factory, beverage factory, soy products, meat products factory, cannery, brewery, pharmaceutical factory, packaging plant, building materials factory, paint factory, swimming pool and other places of the enterprises and institutions.
