Abstract

The utility model relates to a two-purpose boiler for cooking and heating, which is composed of a furnace cover, a top furnace door, a bottom furnace door, a secondary air inlet, a top hearth, a bottom hearth, an ash chamber, a top grate, a bottom grate, an annular radiation heat exchanger, a pipe-array convection heat exchanger, a cold water pipe, a hot water pipe, a V-shaped stop valve, a blower, an ash combustion chamber, an obstructing gate, a chimney and a flue. The utility model is characterized in that: the top hearth is a pot-shaped cavity, the top grate is a downward convex arced surface. According to the different purpose such as cooking and heating, two combustion methods including up-absorption type and down-absorption type are designed, according to the characteristic of biomass forming fuel, the utility model adopts a double-grate structure and has the advantages of dust elimination, adequate combustion and high combustion efficiency, besides, the loss of inadequate combustion of gas and solid is less, the content of dust, NOx and SO2 is low, conforming to the contamination emission standard.

Description

A kind of cooking-heating dual-purpose stove
Technical field
The utility model relates to a kind of stove and accessory, is particularly for a kind of cooking-heating dual-purpose stove.
Background technology
Whole world every year is huge by the biological quality that photosynthesis generates, and it only comes after coal, oil, the natural gas as energy-output ratio, is called the fourth-largest in the world energy, and it is clean regenerative resource.China's biomass straw output reaches more than 600,000,000 ton, is equivalent to more than 300,000,000 ton of standard coal, because the raising of living standards of the people and the variation of energy resource structure, the surplus of stalk is increasing, destroys and not only wastes resource, atmosphere pollution, and influence traffic safety.Utilize stalk alternative ore fuel, realize CO 2Zero-emission reduces the NO in the atmosphere X, SO 2Content to preserving the ecological environment, develops social economy, and implementing the energy sustainable development strategy has major and immediate significance.Straw briquette fuel is the high effect cleaning energy, has the storage of being convenient to, transportation, easy to use and efficiency of combustion advantages of higher.
Based on above reason, the exploitation of biomass molding fuel and popularization have obtained great attention in China, but domestic exploitation and seriously hysteresis of use to the biomass molding fuel combustion apparatus.A lot of units are under the situation of not understanding fully the biomass compact fuel Theory of Combustion, blindly original coal combustion equipment is changed into the biomass molding fuel combustion apparatus, phenomenons such as the volume, shape, heating surface of burner hearth and biomass compact fuel burning do not match appear in improved combustion apparatus inevitably, cause the combustion apparatus efficiency of combustion and the thermal efficiency low, exert oneself and fluid properties decline pollutant load height in the smoke evacuation.
Summary of the invention:
The utility model has designed a kind of cooking-heating dual-purpose stove according to above deficiency.
A kind of cooking-heating dual-purpose stove of the present utility model, form by bell, upper furnace door, lower furnace door, secondary air mouth, upper furnace, lower hearth, grey chamber, upper fire-grating, lower fire grating, ring-type radiation recuperator, tubulation convection recuperator, cold water pipe, hot-water line, 1V type stop valve, air-introduced machine, burning chamber, chamber obstruct door, chimney, flue, it is characterized in that its upper furnace is a protruding cambered surface under kettle shape inner chamber, upper fire-grating are.Stove and accessory is provided with upper and lower two fire doors and upper and lower two fire grates.The lower furnace door place is provided with a secondary air mouth that leads to upper furnace.Be provided with in the lower hearth around the ring-type radiation recuperator of upper fire-grating and by in pipeline and the burning chamber tubulation convection recuperator being set and link to each other.Be provided with the chamber that slides up and down between lower hearth and the burning chamber and intercept door, be used for two chambers of connected sum sealing.
Coming respectively at chimney and flue joint design V-type stop valve, lock closes chimney or flue.The vertical component top of chimney is provided with air-introduced machine.This stove and accessory adopts double-layer grate structure, the design of twin furnace door, according to two kinds of combustion systems of different purposes designs such as cooking and heating, during cooking with common updraft type combustion system, adopt during heat supply in winter and inhale combustion system down, can improve the efficiency of combustion and the thermal efficiency to greatest extent like this, thereby save the energy.
The utlity model has reasonable in design, cheap for manufacturing cost, the efficiency of combustion height, the advantage of low emission has good use promotional value.
Description of drawings:
Fig. 1 is a kind of cooking-heating dual-purpose stove structural representation;
Description of reference numerals
1 bell, 2 upper furnace doors, 3 lower furnace doors, 4 secondary air mouths, 5 upper furnaces, 6 lower hearths, grey chambers 7,8 upper fire-gratings, 9 lower fire gratings, 10 ring-type radiation recuperators, 11 tubulation convection recuperators, 12 cold water pipes, 13 hot-water lines, 14V type stop valve, 15 air-introduced machines, 16 burning chamber, 17 chambers intercept door, 18 chimneys, 19 flues among the figure.
The specific embodiment:
As shown in drawings:
During cooking, lower furnace door (3), V-type stop valve (14) chamber intercept door (17) sealing.Open bell (1) and throw in fuel, upper furnace door (2) supply air is looked cooking and need be determined whether to open air-introduced machine (15).That upper furnace (5) is designed to is dolioform, to increase heat build-up reflex to the bottom of a pan, upper fire-grating (8) is designed to sphere, with the contact area that guarantees to put into abundant fuel and increase fuel and air.
During heating, V-type stop valve (14) upwards rotates sealing flue (19), and chamber intercepts door (17) and opens.Upper furnace door (5) is used to add fuel and adjusts the burning that lower fire grating (9) is gone up fuel, only opens when igniting and scarfing cinder.Lower furnace door is used for ash discharge and supplies with little air, and crack when normally moving, aperture is decided on the combustion case on the lower fire grating.The above space of upper fire-grating (8) is equivalent to air compartment provides oxygen by secondary air mouth (4), space between the last lower fire grating is lower hearth (6), thereafter wall is provided with exhanst gas outlet, the operation principle of this radiator of cooking a meal is: certain particle diameter straw briquette fuel is added in upper fire-grating (8) through bell and inhales burning up and down and heat ring-type radiation recuperator (10) simultaneously, and the stalk that upper fire-grating leaks down is considered to be worth doing and lime-ash burns away to the lower fire grating (9) and burn.Flue gas and part fuel gas that straw briquette fuel forms in burning back on the upper fire-grating burn through the burner hearth that fuel bed, ash bed enter between upper and lower fire grate, and the flue gas that fuel produces on lower fire grating, the outlet flue through between two fire grates flows to the tubulation convection recuperator (11) of burning chamber and back.This combustion system has been realized the substep burning of straw briquette fuel, alleviates straw burning speed, reaches the coupling aerobic and oxygen supply of burning, and straw briquette fuel is stablized continued completing combustion, has played the smoke abatement and dust control effect.
Except that the related technology contents of the utility model, it is known to be those skilled in the art.
