Coal-fired coal-fired steam boiler

Product Range

Evaporation capacity: 2-35t / h, design pressure: 0.7-2.5MPa

Xeneng SZS series coal water slurry steam and hot water boiler is a new generation of environmentally friendly products. It has the characteristics of low fuel cost and low pollutant emissions, and is the best substitute for fuel oil and coal-fired boilers. This series of boilers are natural circulation, room-fired water tube steam boilers, with slightly negative pressure combustion and balanced ventilation. The body adopts two upper and lower drums arranged vertically, the burner is arranged on the front wall, the coal water slurry is fully burned in the furnace (combustion efficiency> 98%), and the high-temperature flue gas generated is horizontally washed by the convection tube bundle through the furnace outlet, The heat is exchanged by the air preheater arranged at the rear of the boiler, and the flue gas is sent to the chimney and discharged into the atmosphere by the induced fan.

Coal water slurry combustion efficiency (> 98%), high boiler design thermal efficiency (close to 90%);

Emissions meet environmental protection requirements in the first class of the country's “Boiler Air Pollutant Emission Standards”;

Adopting the pre-stable combustion furnace structure and reasonable furnace section and volume, the product can adapt to the combustion of a variety of coal water slurry and effectively control the coking phenomenon of the furnace.
