Description

The environmental protection coal burning boiler that looses

The utility model belongs to the not direct technical field of heat-exchange apparatus of contact of heat exchange medium.

Our used unpressurized hot water boiler will reach environmental requirement now, makes it not over-emitting black exhaust, and is free from environmental pollution, is very very difficult.Must burn the shape coal or add other smoke eliminating equipment, make that the operating cost of boiler is high especially.

The purpose of this utility model provide a kind of simple in structure, volume is little, shape coal and diffusing coal can both reach environmental requirement, the energy-conservation environmental protection coal burning boiler that looses by abundant burning.

This environmental protection coal burning boiler that looses, comprise body of heater, in body of heater, connect and compose the inner furnace body that has many flues on its of water chamber with body of heater, be contained in the fireguard of burner hearth hypomere, on fireguard, be welded with burner, one end is communicated with burner, the other end passes the ajutage of body of heater, epimere at burner hearth is connected on the inner furnace body, one end inserts the heat pipe in the water chamber, one end stretches out the chimney that body of heater upper end one end is communicated with burner hearth, in burner hearth, build firebreak in the throat lower end, return pipe in the body of heater upper end with the water chamber circulation, atmospheric communicating pipe in the body of heater upper end with the water chamber circulation, at the outlet pipe of body of heater hypomere and water chamber circulation, be located at the firing door of body of heater hypomere.

This environmental protection loose the burner of coal burning boiler be can balanced ventilation in burner hearth around it combustion-supporting.

Because hot flue gas is to deliver to chimney by many flues of inner furnace body, heat exchange area is big especially, the heat exchanger effectiveness height burns the coal of same quantity, and the temperature that water reaches in the boiler is than the equal boiler temperature height of other model, burner is arranged in the burner hearth, in burner hearth, blow uniformly, make coal combustion ground abundant especially, institute's quantity of heat production height, the fire box temperature height, energy-conservation.

Accompanying drawing shows embodiment of the present utility model, wherein:

Figure 1 shows that the elevational cross-sectional view of the diffusing coal burning boiler of environmental protection;

Cutaway view is looked on a left side that Figure 2 shows that the diffusing coal burning boiler of environmental protection;

Figure 3 shows that the vertical view of the diffusing coal burning boiler of environmental protection;

The coal burning boiler that looses of environmental protection as shown in the figure comprises body of heater 1, and body of heater 1 is the b font.In body of heater 1, connect and compose the inner furnace body 2 that has many flues 15 on its of water chamber with body of heater 1, be welded on the fireguard 5 of burner hearth hypomere, on fireguard 5, be welded with burner 3, burner 3 be can be around it the combustion-supporting of balanced ventilation in the burner hearth, the ajutage 4 that an end is communicated with burner 3, the other end passes body of heater 1.Epimere at burner hearth is connected on the inner furnace body 2, an end inserts the heat pipe 6 in the water chamber, and heat pipe 6 is a super heat-conductive pipe.One end stretches out the chimney 8 that body of heater 1 upper end one end is communicated with burner hearth, in burner hearth, build firebreak 7 in the throat lower end, return pipe 12 in body of heater 1 upper end and water chamber circulation, atmospheric communicating pipe 13 in body of heater 1 upper end and water chamber circulation, at the outlet pipe 14 of body of heater 1 hypomere and water chamber circulation, be located at the firing door 10 of body of heater 1 hypomere.Be located at the lighting door 9 on the protuberance of body of heater 1 hypomere, be located at the shoot door 11 of body of heater 1 epimere.
