Eco-friendly coal-fired steam boilers body is composed of longitudinal upper and lower drum and convection tube bundle. The upper and lower drum is longitudinal arranged. The combustion equipment uses chain belt type chain grate and is driven by stepless variable speed device. Decorate Φ 51 * 3 tubes in combustion chamber wall, the inside the drum is equipped with separation and continuous drainage device; The boiler drum is equipped with regular sewage discharge device to ensure the quality of steam. Equipped with continuous automatic feed water device to ensure the safe operation of the boiler, boiler tail layout economizer.
50 tons coal fired steam boilers common models are DHL sales Angle pipe coal-fired boiler, SZL series vertical double drum type chain grate boiler, DZL series vertical single drum type chain grate boiler, SHX series circulating fluidized bed boiler, DHX series circulating fluidized bed boiler with SHL series double drum bulk chain grate boiler, the boiler pressure rated 1.6 Mpa, 1.25 Mpa, 2.45 Mpa, 3.82 Mpa, 5.3 Mpa, and so on. The chain grate coal fired boiler is generally adapted to high quality coal, anthracite and other coal, circulating fluidized bed boiler is suitable for all kinds of coal.
The calculation formula for coal consumption of 50 tons coal-fired steam boiler is coal consumption per hour = boiler power *3600/ coal combustion heat/boiler efficiency. If the calorific value of coal is calculated by 29MJ/KG and the boiler efficiency is calculated by 76%, the coal consumption per hour of 50 tons of coal-fired steam boiler is 35MW*3600/29MJ/KG/76%=5717kg. Of course, this is only a rough calculation. The combustion efficiency of ZOZEN coal-fired boiler can reach more than 82%, which can more effectively save fuel costs for users.
SZL series coal-fired boilers have high degree of automation, boiler feed water automatic regulation, high and low water level alarm, low water level interlock protection, induced draft fan, blower interlock protection. This series of boiler feed water, slag discharge and other operations mechanized, complete supporting machines. This series of boiler has the steam pressure automatic regulation system, boiler steam pressure automatic regulation system control system into the working state, when meet the necessary combustion conditions: when the steam pressure in the boiler is higher than or equal to the set pressure limit when the limit, the control system output stop signal.
This coal-fired steam boiler has compact structure design, small footprint, beautiful appearance, simple operation, stable operation, fast heating, fast pressurization, large output and strong adaptability to coal. Coal-fired boiler sales price is different according to the configuration, if you want to get a quotation welcome to email email@example.com and online chat to provide detailed requirements, our engineers will customize the boiler system and quotation for you.
