Coal-saving stove core

Abstract

The invention discloses a coal-saving stove core which comprises a core body (1), a closed ring (2), a space ring (3), a hearth (4) and a fire restraining barrel (5), wherein the core body (1) is cylindrical; the closed ring (2) is connected to the top of the core body (1); an air vent (6) is arranged at the upper waist part of the core body (1); the closed ring (2) is annular; an outer ring of the closed ring is fixed on the core body (1); the space ring (3) is annular and covers the hearth (4); the outer ring of the space ring is fixed at the upper waist part in the core body (1); the dimension of an inner ring of the space ring is consistent with a fire hole of the hearth (4); the hearth (4) is in the shape of a vertical clock and abuts against the core body (1); the fire restraining barrel (5) is a barrel body with a thicker upper part and a thinner lower part; an outer ring of the top of the barrel body is provided with or is not provided with an annular edge (8); and an air inlet (7) is arranged at the upper waist part of the barrel body. The stove core has the following advantages that: firstly, a lot of coal consumption can be reduced; secondly, the combustion condition of a coal stove is improved, and the combustion efficiency is increased; thirdly, gas emission can be greatly reduced, and the stove core is beneficial to protecting the environment; fourthly, the heating temperature raises quickly, and the ignition is also quick; fifthly, less coal is combusted, less dust is discharged, and garbage can be reduced; and sixthly, the space ring is durable and is not easy to burn out. The coal-saving stove core is suitable for a heating coal stove.

Description

technical field [0001] This invention relates to dry stoves and, in particular, to stove cores. Background technique [0002] Most of the common coal stoves have a straight cylindrical furnace core. Coal is put into the furnace and burned on the furnace bridge, and the coal slag is discharged from the furnace bridge. But the thermal efficiency of this kind of stove is not high, and it is not coal-saving. In order to improve its thermal efficiency, people have developed many technical solutions. In the Chinese patent literature, the applications involving coal furnace cores are: No. 88105714.2 "Expanded Perlite Honeycomb Furnace Core", No. 92220852.2 "Four-ring Type Honeycomb Cake Furnace Core" , No. 200420105309.9 "energy-saving coal-fired furnace core", No. 200720032929.8 "energy-saving furnace core", etc., although these patented technologies all have energy-saving effects, the effect is not ideal. Contents of the invention [0003] The object of the present invention ...
