SZL Series Coal Fired Hot Water Boiler

SZL series water tube hot water boiler is a double boiler tube chain grate boiler.The boiler body is provided with two boiler cylinders arranged longitudinally along the center of the boiler. The front of the upper boiler cylinder and the water-cooled wall tubes on both sides constitute the radiant heating surface of the furnace, and the tube bundles between the rear of the upper boiler cylinder and the lower boiler cylinder constitute the convection heating surface.The economizer is arranged at the back of the boiler. After some heat is absorbed from the furnace, the high-temperature flue gas generated by combustion enters the convection heating surface through the burnout chamber to conduct heat transfer. Then the flue gas is sent to the chimney and discharged into the atmosphere through the economizer and the dust collector.Compact structure, small floor area, single boiler room layout, capital construction investment province;High degree of assembly, short installation cycle, less installation cost;The heating surface is arranged sufficiently and reasonably, the boiler heats up, boosts the pressure quickly, the output is sufficient, the thermal efficiency is high;Grate air warehouse into the warehouse, the wind volume of each warehouse can be adjusted independently, grate stepless speed regulation, adapt to a wide variety of coal, full combustion;Electronic control cabinet is equipped with complete automatic control and monitoring instruments, high degree of automation, safe and reliable, easy to operate.
