Coal fired hot water boiler

1. The heat efficiency is 4-5 percent higher than the national standard because of the rational collocation of the heat surface and burning equipment.
2. Rational smoke speed design, the heat surface has no ash aggradations and wearing, boiler heat surface can run with high efficiency, full loads and safety.
3. The high furnace is useful for designing rational Boiler Arch, improve the burning efficiency and eliminate black smoke.
4 Unique loop design, rational shoot-directing cycle for hot water boiler, the medium flow speed in the heat surface loop is higher than national standard.
5 Adopt squama style or beam style chain grate, little coal lost, convenient in burning adjustment.
6.  The soot of grate out-let separates due to inertia, which can reduce ash thickness in the outlet gas and the wearing to the back part heat surface efficiently.
7. Compact structure, installation height is less by 35m than other same capacity boilers, which shortens the installation period and reduces the cost of boiler housing.
8. Eliminate ash in obturation condition, which can avoid the second pollution and can save time and strength.
9.  The capacity for water is large, which is used for protection when cutting electric and strengthens the ability to adapt load changes.

(above 20t/h and 14MW)

4. Unique loop design, rational shoot-directing cycle for hot water boiler, the medium flow speed in the heat surface loop is higher than national standard.
5. Adopt high strength and large block grate, add trolley to large type grate, improve the security. Meanwhile, the grate is little coal lost and easy burning adjustment.
6. The soot of grate out-let separates due to inertia, which can reduce ash thickness in the outlet gas and the wearing to the back part heat surface efficiently.
7. Compact structure, installation dimension is smaller than other type boilers, which shortens the installation period and reduces the cost of boiler housing.
8. The capacity for water is large, which is used for protection when cutting electric and strengthens the ability to adapt load changes.
