Fig. 2 is that the gas fired-boiler shown in Fig. 1 is in the floor map of removing after front shroud;
Fig. 3 is that the gas fired-boiler shown in Fig. 1 is in the floor map of removing after back shroud;
Fig. 4 is the schematic perspective view in an embodiment of expansion tank of the present utility model.
Detailed description of the invention
Below with reference to each embodiment shown in the drawings, the utility model is described in detail.But these embodiments do not limit the utility model, the conversion in structure, method or function that those of ordinary skill in the art makes according to these embodiments is all included in protection domain of the present utility model.
Gas fired-boiler is taking fuel gas as fuel, as natural gas, town gas, liquefied gas, biogas etc., carrys out heating water to meet the demand of user's central-heating and/or domestic water by burning combustible gas.
Referring to figs. 1 through a detailed description of the invention of the gas fired-boiler of the present utility model shown in Fig. 3.This gas fired-boiler 1 comprises a shell 10, is housed in burner (not shown) and main heat exchanger (not shown), the expansion tank 20 in shell 10 and is positioned at water route module 30 of shell 10 inner bottom parts etc.
In present embodiment, shell 10 is roughly cubic, and it can be formed by some panel splicings, as front shroud, backboard, top board, base plate and pair of side plates.Shell 10 can be installed on body of wall, and its backboard is towards body of wall.
Burner generally includes burner shell, is provided with burner unit in it, as the some fire row sheets that are arranged side by side.On each fire row sheet, can be provided with the hybrid channel of combustion gas-air, the combustion gas of carrying by gas supply pipe road and air mix and pass to the fire hole that is positioned at fire row sheet top with burning producing heat in this hybrid channel.Because structure and the layout of fire row sheet are well known to those skilled in the art, so applicant is no longer repeated at this.
