Abstract

This stove is composed of a housing, a heat insulation course, a secondary air channel, a self-preheating device and an internal stove. The outside of the stove is mainly equipped with an upper air inlet with the function of preheating the cold air used as combustion-supporting air. The upper air inlet is also an exit for heating with the hot air, a lower slag hole and a secondary air intake. This stove can reduce the losses of the chemical incomplete combustion, and also reduce the heat dissipation losses. Compared with heat-insulating materials of same unit heat dissipating capacity with the same dimension, the stove is about 70% lower than the others. The stove can utilize residual heat to increase the temperature of the combustion-supporting air. The stove saves about 20% coal than a secondary air fuel-economizing stove. The stove saves about 50% coal than the common coal stove, and it is mainly used for the household cooking and heating.

Description

High-efficient self-preheating multi-purpose coal-saving stove

The utility model belongs to domestic stove, and a kind of efficient secondary air self-preheating is used coal-saving stove more.

Application number is 89213170.5 to disclose a kind of efficient secondary air Energy-saving coal stove, it adopts secondary air inlet structure, solved preferably about general coal stove and can not fully burn, the problem that the thermal efficiency is low, but its utilize problem and surface radiating of not solving fume afterheat lose.

Application number is that 88209906. χ double-purpose energy-saving hot-blast stoves can utilize fume afterheat, solved the surface radiating loss preferably and utilized waste heat to add hot-air for heating usefulness, but it fails to solve well the thermal loss that burn incompletely causes.It can not utilize waste heat to come warm-up combustion-supporting air.

The purpose of this utility model provides a kind of secondary air that has, and energy self-preheating combustion air, and can be with the hot blast heating, also can use the coal-saving stove of honeycomb briquette and lump coal, and it can make coal fully burn, and reduces thermal loss.

How efficient secondary air self-preheating is shell, thermal insulation layer, secondary air self-preheating device composition with the primary structure of coal-saving stove.Secondary air self-preheating device is one band flue directly, but also secondary air self-preheating device direct one band flue adds flue in addition again, and its main member is a secondary air self-preheating device.Secondary air self-preheating device mainly contains self-preheating combustion air passage and self-preheating secondary air passage constitutes.Mainly contain self-preheating combustion air air inlet on stove outer covering, following slag notch also has one or several secondary air mouth.Secondary air self-preheating device and flue can directly be made of one with a kind of material, and also available different materials is fixedlyed connected with flue with the face way of contact.Its flue shape can be respectively be as awl tubbiness or burner hearth that arcs of recesses is adapted to honeycomb briquette or diffusing shape lump coal uses.

Below in conjunction with description of drawings specific embodiments of the present utility model:

Fig. 1 is efficient secondary air preheating coal-saving stove structural representation.

As shown in FIG.: 1-insulating, 2-shell, 3-stove upper edge, the 4-gripper shoe, the last air inlet of 5-, 6-flue, 7-annular secondary air road, 8-preheating table, 9-secondary air next door, the pre-hot-flow flue of 10-, 11-secondary air road, 12-dowel, the 13-air inlet, 14-insulation material interlayer, slag notch under the 15-, 16-supported hole.

How efficient secondary air self-preheating is shell with the honeycomb briquette stove ragged edge of coal-saving stove, then is heat-insulation layer, secondly is the self-preheating device of secondary air again, secondly is heat-insulation layer again, is flue then.When static, mainly constitute by shell, heat-insulation layer, secondary air self-preheating device, flue etc.Appearance has crater, last air inlet, secondary air mouth, down slag notch is arranged.When coal is put into the flue internal combustion, shut suitable for readingly, open end opening and just be equivalent to efficient secondary air coal-saving stove.When end opening is shut, last air inlet is opened, combustion air enters from last air inlet, make the combustion air preheating through the self-preheating device, flow through the expression direction, enter flue then and carry out combustion-supportingly, it is more abundant than the burning of efficient secondary air coal-saving stove like this, firepower is bigger, the very hot oven time is longer, the thermal efficiency higher economize on coal more.If last air inlet, following slag notch are opened simultaneously, next combustion-supporting with regard to some wind from the air that following slag notch advances, another part carries out preheating through the self-preheating device.Preheated air flows out through uptake then, just can warm oneself in some pipeline inlet chambers.This stove also can be with chimney, directly cooks and the hot blast heating indoor the heating.Outside the institute that keeps energy-conservation honeycomb briquet stove of efficient secondary air and double-purpose energy-saving hot-blast stove possesses some good points, the characteristics of warm-up combustion-supporting air and use lump coal have been added again.It is than secondary air coal-saving stove unit heat dissipation capacity low 70%, simultaneously it can warm-up combustion-supporting air to 150 ℃～and 250 ℃, can economize on coal about 20% like this, it economizes on coal about 20% generally than efficient secondary air energy saving briquette stove on the whole, when warming oneself, economize on coal about 50% than double-purpose energy-saving hot-blast stove without hot blast, when warming oneself with hot blast comparable it economize on coal 30%, it is with, a kind of coal stove that the efficient of economizing on coal is high more than one in a word.
