ZOZEN fully considered the effects of altitude and atmospheric pressure on gas-fired steam boilers when designing the boiler system solution. On the one hand, owing to the decrease of atmospheric pressure, the combustion speed of fuel slowed down. The designers of ZOZEN properly increased the furnace volume and the convective heating surface area to ensure the heat transfer effect. On the other hand, the air volume and pressure should be modified when selecting a burner, which can ensure the boiler output and the thermal efficiency of the entire boiler system.
The chain grate boiler is a very mature boiler type, which has the characteristics of simple operation and easy to master, is widely used in all walks of life. As a large-scale enterprise engaged in R&D and manufacturing of boilers for over 30 years, ZOZEN produces various series of energy efficient chain grater boilers, which are favored by customers.
The structure of the chain grate boiler is generally divided into the lower grate and the upper drum. The solid fuel enters the chain grate through the hopper. Stratified combustion technology is applied to the fuel as the chain grate moves, and the entire combustion process is completed on the grate. Solid fuels do not require pipe laying and so chain grate boilers are relatively inexpensive. The system of chain grate boilers has the advantages of simple structure, low cost of construction and operation, but there are also some defects.
