2, on coal-burning boiler front panel of the present utility model, temperature display watch is installed, can shows the temperature of water in water jacket, for control combustion is provided convenience.
3, on coal-burning boiler of the present utility model, be provided with shutter, and be provided with air inlet on shutter, can need to control intake according to heating.
4, on coal-burning boiler of the present utility model, be provided with the kitchen range mouth for cooking, can manufacture hot water and cook, have multi-functional.
5, on coal-burning boiler of the present utility model, be provided with smoke box, and, adopt counter-burning type structure, can fully absorb the heat that burning produces, exhaust gas temperature is low, and the thermal efficiency is high, meets environmental requirement.
Accompanying drawing explanation
What Figure 1 shows that the anti-front view that burns smokeless coal burning boiler of the utility model partly cuts open figure;
Figure 2 shows that the A-A cutaway view in Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The schematic diagram that the utility model is counter burns smokeless coal burning boiler as depicted in figs. 1 and 2, comprise base 1, inner furnace body 2, shell 3 and smoke box 4, described base 1 inside is separated into front Dust Storage Room 6 and rear Dust Storage Room 7 by deep bead 5, on described front Dust Storage Room and rear Dust Storage Room, be separately installed with shoot door 8, described inner furnace body 2 front portions are coal store 10, the rear portion of described inner furnace body is provided with described smoke box 4, described coal store internal upper part is separated into front combustion chamber and after-burner by heating spacer 9, described inner furnace body rear portion becomes water containing chamber 11 and smoke chamber 12 by baffle for separating, in described smoke box 4, be provided with the second water jacket with described water containing chamber 11 one, the second water jacket inside of described smoke box is provided with the many smoke pipes 13 that are communicated with smoke chamber 12 and ambient atmosphere, in described water containing chamber 11, be provided with the many fire tubes 14 that are communicated with after-burner and smoke chamber.Described shell 3 encases described inner furnace body 2, between described shell 3 and described inner furnace body 2, forms the first water jacket, and the many water pipes 22 that are communicated with described the first water jacket are installed in described after-burner.Between described front Dust Storage Room and described coal store, fire bars 15 is installed, on described fire bars, is connected with deashing rocking arm.The cigarette ash of many described smoke pipes falls in described rear Dust Storage Room.The inner furnace body corresponding with described coal store and shell place are provided with coal filling hole 16, and described heating spacer, the first water jacket, the second water jacket water containing chamber are interconnected and are provided with water inlet and delivery port.
