Specific embodiment
To make the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
The utility model provides a kind of bulging odd test from preheated burning plane heater.
As depicted in figs. 1 and 2, in the heater, heating flat board 3 is covered in spiral reverse flow heat exchanger, burner 7
In closed cavity below spiral reverse flow heat exchanger, combustion zone 4 is reserved on the top of burner 7, and air conducting area 8 is located at combustion
The lower section of burner 7, the connection blast tube 9 of burner 7, igniter 1 and flame monitor 2 pass through burner 7, igniter 1 and flame
Monitor 2 is arranged on the combustion zone 4 of spiral reverse flow heat exchanger, as shown in Figure 3 and Figure 4, in the middle of spiral reverse flow heat exchanger
Every distribution preheated air passage 5 and exhaust gases passes 6.
Wherein, preheated air passage 5 and extraneous junction are combustion air inlet 10, and drum is connected at combustion air inlet 10
Blower fan；The end of exhaust gases passes 6 is exhanst gas outlet 11 with extraneous junction, and air exhauster is connected at exhanst gas outlet 11.
