A
water saving and energy saving
low noise oil gas
dual purpose blast
hearth, wherein the burner is composed of an inner and an outer fire vessels, the top
nozzle of the wind
pipe is screwed on the bottom pot of the outer fire vessel, the bottom
nozzle of the wind
pipe is screwed with a
pipe plug, the center of which is provided with a tubing head base, the central hole of the tubing head base is communicated with a
fuel gas assistant burning supply pipe, the center of the inner fire vessel if provided with a tubing head cap seat, the center of which is provided with an air outlet. The center of the wind pipe is equipped with a sleeve, the upper end of which is screwed with the tubing head cap seat, while the lower end is in gap matched with the tubing head cap seat. The central
nozzle of the wind pipe is connected with a fan, a heat insulating mattress is arranged between the
flange on the inner fire vessel upper part and the circular
flange of the outer fire vessel upper part, the side walls of the inner and the outer fire vessels are opened with screws, and the air inlet pipe traversely passes through the
interlining chamber between the inner and the outer fire vessels to screw with the bolt hole. The invention is provided with conflagration and nagaaki fire, which controls the conflagration by the foot valve to save
fuel gas; and provided hot water using the remaining heat, meanwhile reduces the temperature of the
hearth, saves water with small fan and
low noise.
