Research on Chain Grate Combustion Model

The types of coal-fired boilers are divided according to the structure of boilers. They can be roughly divided into vertical life coal-fired boilers, horizontal-water-fired coal-fired boilers, and horizontal water-fired-tube coal-fired boilers. Horizontal coal-fired boilers can be subdivided into There are two types of D0 and O0 types. These types basically cover all of the coal-fired boilers in use in Xining City, of which the vertical live boilers all use the fixed grate without exception, and the chain grate combustion methods are mostly used by the latter two types of boilers. The main differences between gas and coal and the basic principles of transformation. Because of the high altitude, such boilers often suffer from defects such as insufficient output and serious pollution. Regardless of the specific form of the vertical live boiler, its internal structure is similar, and arc arches are arranged in the hearth. Vertical boiler renovation features.

There is little room for furnace reform. The most common method is to remove the grate and support, and expand the ash layer as part of the furnace. If it is a double grate, if the flame is jetting water to cool the grate, refractories must also be used as the lining to reduce the fouling rate in the grate. Due to the weak flame radiation ability of gas, it is generally required to add two times of radiation heating surface in the furnace. When convenient, the heat-receiving surface of the tail is set externally in order to increase the thermal efficiency of the boiler. Vertical boiler reform program. Remove the fixed grate and its supporting body; transform the ash removal room, and lay two fire bricks, place a certain thickness of refractory bricks on it; arrange the burner horizontally or at a certain angle with the level; close the house with firebrick Doors; equipped with controls containing high-energy ignition, flame monitoring and flameout protection.
