Abstract
The utility model relates to a household coal stove, particularly a far-infrared household coal gasifying stove using phi 100 mm honeycomb briquette balls. The utility model is provided with a twofold heating annular tube array residual heat boiler and a steam operated centrifugal blower, and a scale control handle is arranged on the bevel part at the front upper part of the utility model for accurately and conveniently regulating. Because the residual heat is reasonably and fully utilized, the utility model can be used for roasting and steaming foods and heating water at the same time of cooking a fried dish, and the utility model reduces the labour intensity, enhances the cooking efficiency, saves the energy and reduces the air pollution.
Description
The utility model is about domestic briquet stove, particularly to using the far-infrared household coal gasification furnace of φ 100mm honeycomb briquette, the annular tubulation arcola of a dual-heated is housed around the flue of this stove; Designed a steam-operating formula centrifugal blower at the bottom air inlet; Air door, steam regulating handle are the scale formula; Also have far infrared baking box, steam box, water tank etc.
To the transformation of family expenses φ 100mm honeycomb briquette stove, the problem of running into is more.Some present household fuel gas producers, the method of bringing water vapour when blowing with electric blower mostly into produces water-gas, this method is not only wanted consumed power, and brings many inconvenience in the use, more can't normally use at nothing electricity and frequent power failure area.Other method is provided with miniature boiler on stove, produce water-gas with the method for steam direct injection, and steam consumption quantity is big like this, and air capacity is not enough and can not fully mix.This method generally also all is used on the above coal stove of φ 120mm.If this method is used on the φ 100mm honeycomb briquette stove, because flue area of dissipation and calorific intensity are littler, the steam that boiler produced is used for not enough spraying and produces water-gas, more impossiblely removes to supply steam heaters such as steam box, water tank again.
The waste heat that the utility model purpose has been to solve φ 100mm honeycomb briquette stove rationally utilizes, the problem of the generation of water-gas and raising cooking efficient aspect.
Concrete scheme is: in flue 2/3 garden circumferential portion an annular tubulation arcola is housed, this boiler has increased the steam raising amount by the smoke evacuation dual-heated in flue heat radiation and the tubulation.At the bottom of stove air inlet a steam-operating formula air blast is housed, water vapour from boiler 0.05MP pressure is blown in the impeller tangential direction, after the impeller rotation, enough air from the air inlet of air blast enter and with send into the burner hearth that is burning after steam fully mixes, make the coal-fired constantly gasification in the burner hearth produce water-gas, firepower is strengthened, and burning fully.
Because adopt the pneumatic type centrifugal blower, steam consumption quantity is few, steam pipe φ 1.5mm is just enough, still has most of steam to can be used for steam box and water tank.The steam distribution joystick of this stove indicates 1 to 6 lattice scale in 90 ° of angles, operating position is located at place, front upper part inclined-plane, but cooking limit, limit control firepower size and steam flow.
This stove is provided with the baking box of far-infrared paint in flue 1/3 garden circumferential portion, can bake various food; Steam box can the placement capacity be two in the lunch box of 0.5Kg rice, also can place tablewares such as homely bowls and chopsticks and carry out disinfection; Water tank can be placed the 6Kg clear water; Ash discharge adopts drawer type; Inlet and outlet water circulating valve when utilizing the water intaking valve of boiler and blowoff valve to can be used as the hot-water heating heating.
Family uses the advantage of this stove: the one, and the coal briquette that this stove uses conforms to the specification of market supply, and honeycomb briquette φ 100mm is the whole nation the most universal the most general specification.The 2nd, alleviate cooking labour intensity, improve cooking efficient.Than using the liquefied gas time fast again, in cooking, can bake steaming food and boil water.The four entrees and a soup of general family a meal comprises that rice can be all burned in 30 minutes.The 3rd, burn fully, fully rationally utilize waste heat, also have the small loss except that smoke evacuation and shell according to measuring and calculating, integrated heat efficiency can reach about 65%, because burning is fully, can reduce atmosphere pollution.
Accompanying drawing has been described the shape and the primary structure of far-infrared household coal gasification furnace.
Accompanying drawing 1: be the outline drawing of facing of far-infrared household coal gasification furnace.
Accompanying drawing 2: for looking outline drawing in a left side.
Accompanying drawing 3: be the locational A-A profile of Fig. 2.
Accompanying drawing 4: be the locational B-B profile of Fig. 2.
Fig. 1, described the far-infrared household coal gasification furnace and faced profile.In shell (9) outside the boiler water gauge (1) of observing water level is housed; Steam-driven blower admission joystick (2); The steam handle (3) of steam box is regulated and control steam to steam box (8); The steam regulating handle (4) of water tank; Boiler deadweight safety valve (6) automatic control steam≤0.05MP; Ash discharge drawer (10) is arranged at the bottom; The stovepipe on right side (7) can be connected to outdoor; A pot frame (5) is arranged above but frame is put all kinds of bowls.
Far infrared baking box (12) has been looked on Fig. 2, a left side; Scale formula air register handle (11); The backheat water circulating valve that the advances when water intaking valve of boiler (13), blowoff valve (14) can be done the hot-water heating heating uses.
Fig. 3, circumferential alignment pipe boiler (18) and far infrared baking box (12) are housed in flue (16) periphery, the steam that is produced by boiler (18) blows in the steam-operating formula centrifugal blower (22), the gaseous mixture of air and steam blows in the burner hearth (15) by air door (21), make coal-fired gasification, produce coal gas, strengthen burning, behind the flame heat the bottom of a pan, flue gas enters in the tubulation of boiler (18) by last pot frame (5) exhaust smoke hole (17) on every side, is discharged to outdoor through flue (19) chimney (7).Because both by flue (16) heat radiation, by the smoke evacuation dual-heated in the tubulation, its quantity of steam was enough supplied with steam box (8) and water tank (20) to boiler (18) simultaneously again.
The layout of Fig. 4, flue (16), boiler (18), far infrared baking box (12), flue (19), the vacant part of stove is filled with insulation material (23).
The profile of this stove, long 450mm, wide 360mm, high 710mm, net weight 25Kg.Flue is the fire-resistant courage of clay matter; Steam-driven blower shell aluminium, blade 0.2mm corrosion resistant plate; Boiler 2.5mm steel plate; Baking box is coated with far-infrared paint with the 1mm steel plate; The all available 0.5~1mm aluminium sheet of steam box, water tank and shell; The joystick bakelite; Pipe valve is all used the market general part.
According to the basic principle of this stove, be incorporated on the stove greater than φ 100mm, performance will be more good.
