Abstract
The utility model relates to a furnace door of novel coal-fired furnace, which belongs to the technical field of furnace door structures of coal-fired furnaces. The furnace door of novel coal-fired furnace comprises a fire hole arranged in a furnace body and a furnace front door (1) which is connected with the fire hole, wherein the furnace front door (1) is connected with a handle (2) for closing. The furnace door of novel coal-fired furnace is characterized in that the fire hole is provided with an interlayer structure, an inner layer (4) is combined with the inner container of the furnace body, an outer layer (5) is combined with the outer container of the furnace body, and an interlayer (6) for containing water is arranged between the inner layer (4) and the outer layer (5) of the fire hole. The furnace door of novel coal-fired furnace has reasonable structure, excellent seal property, uneasy deformation, high efficiency, energy saving and safe and convenient operation, which can avoid heat loss of the fire hole through adopting the interlayer structure, and is not easy to generate the phenomenon of smoke return and smoke leakage.
Description
One, technical field
The utility model relates to a kind of novel coal furnace door, belongs to coal furnace door structure technical field.
Two, background technology
At present the fire door of boiler is a single layer structure, fire door easy deformation during burning, and poor sealing performance has not only been wasted the heat of fire door fire, and the phenomenon that often produces cigarette, leaks cigarette during burning, brings unnecessary trouble to the operator.
