Problems solved by technology

The cooker produced by this technical scheme is energy-saving and hygienic, but this kind of scheme also has some defects, that is, if useful pressure steam is to be produced, the production requirements for the sealed water tank are very high, and the production requirements for pressure vessels must be met. The steam outlet diameter of the large water tank reduces the steam pressure, so the main function of the water tank can only be to produce hot water

Embodiment Construction

[0008] The energy-saving draft-drawing coal-fired stove is composed of a coal-fired stove (1), an induced draft pipe (2), a waste heat boiler (9) and a draft fan (11) connected in series. One end of the air induction pipe (2) is sealed to it, the other end is sealed to the air inlet (3) of the waste heat boiler (9), and the air outlet (12) of the waste heat boiler (9) is connected to the air outlet of the exhaust fan (11) Sealed connection. The coal-burning stove (1) can be selected as a single-eye stove, or a multi-eye stove with tuyere outlets connected in series or in parallel. The waste heat boiler (9) should at least include a casing (13), an air inlet (3), an air outlet (12), an air passage (4), a water inlet (5), a sewage outlet (14), a safety valve (6), Pressure gauge (7), steam switch (8), water level gauge (10), air inlet (3), air outlet (12), water inlet (5), sewage outlet (14), safety valve (6), pressure gauge (7), steam switch (8), water level gauge (10) are arr...

Abstract

An energy-saving air-draught coal - fired range is prepared by connecting coal - fired range, draught tube, exhaust-heat boiler and draught fan in series. The device works totally in semi-closed draught mode to let air flow under internal draft condition so there is no dust in the room and the surplus flame and heat are led to exhaust heat boiler so energy saving purpose can be achieved.

Description

Technical field [0001] The invention belongs to a coal-fired stove, which is especially suitable for use in kitchens in hotels, restaurants, hostels, canteens of units and other places. Background technique [0002] In the patent No. 02218704.9 of my application for a double-burner air-drawing type coal-fired stove, it is disclosed that the method of drawing air is used to support combustion, and the stove is penetrated in a sealed water tank, and the redundant flame in the stove and the The heat is introduced into the water tank, the water tank is heated, and the technical scheme of producing hot water and steam. The cooker produced by this technical scheme is energy-saving and hygienic, but this kind of scheme also has some defects, that is, if useful pressure steam is to be produced, the production requirements for the sealed water tank are very high, and the production requirements for pressure vessels must be met. The steam outlet diameter of the large water tank reduc...
