Description
Technical field
The utility model belongs to the domestic boiler that uses solid fuel, and particularly uses the household cooking and warming stove of fire coal or stalk fuel.
Background technology
The domestic boiler that uses in the vast urban and rural residents of northern China is domestic heating cooking boiler for dual purpose mostly, and the fuel of employing mainly is coal-fired.The structure of this household cooking and warming stove is that the wall of body of heater adopts the water cooled furnace wall, and the flue that is positioned at the upper back, combustion chamber leads to the water-cooled chimney, and the water jacket of water-cooled chimney is communicated with the hot-water heating furnace wall.This radiator of cooking a meal not only can be used to cook, and the heated hot water domestic waters such as room heating, bathing of can buying a house in installments in the water cooled furnace wall.Its weak point is owing to will satisfy indoor heating usefulness in winter, must be with the chamber design of cooking-heating dual-purpose stove bigger, the fuel of sufficient amount can be housed in burner hearth, and the burning of sufficient fuel just can make hot water temperature and the amount of the hot water requirement that reach indoor heating of heating in the water cooled furnace wall.But at the non-heating season joint, use this cooking-heating dual-purpose stove to cook, because the Capacity Ratio of burner hearth is bigger, it is many to consume fuel, causes the waste of fuel.The heat exchange area of the flame of fuel combustion in stove is little, and the thermal efficiency is low.In addition, need bank up a fire night at the cooking-heating dual-purpose stove that heating season uses, this cooking-heating dual-purpose stove device of not banking up a fire adopts the foam coal to bank up a fire.Often grasp badly, it is tight to bank up a fire, and coal-firedly lacks oxygen and makes boiler flame-out; It is not tight to bank up a fire, then the after-flame soon of the fuel in the stove.In addition, this cooking-heating dual-purpose stove can only use fire coal, uses fuel type single, the fuel price height.
Summary of the invention
The purpose of this utility model is to provide a kind of household cooking and warming stove that uses fire coal or stalk fuel, and not only it is rational in infrastructure, and heat exchange area is big in the stove, thermal efficiency height, and can be fit to use fire coal or stalk to act as a fuel, can also bank up a fire easily, easy to operate, fuel savings.
The purpose of this utility model is achieved in that a kind of household cooking and warming stove that uses fire coal or stalk fuel, comprise body of heater with water cooled furnace wall, ventilation deashing chamber, fire grate, burner hearth and flue are being set in body of heater, the bottom that has water cooled furnace wall and the water-cooled head plate that has the fireworks outlet behind the water cooled furnace wall of charge door and the burner hearth that top is provided with exhaust opening and be positioned at both sides in burner hearth is provided with the water-cooled sidewall that returns fiery passage and constitutes the combustion chamber jointly, in the combustion chamber lower fire grating above upper fire-grating is being set, the combustion chamber is separated into upper combustion chamber and lower combustion chamber.In the fireworks outlet of water-cooled head plate, fire sealing cover is installed.
When using the utility model heating, mainly use lower fire grating and lower combustion chamber in heating season.Because there are enough capacity the combustion chamber, fuel combustion is for outside cooking, and heated hot water can guarantee the needs of heating and domestic water in the body water-cooling furnace wall.At the flame of combustion chamber fuel combustion, can upwards flow by the fiery passage that returns of the outlet of the fireworks on the book cold roof plate and lower combustion chamber's both sides water-cooled lower sidewall, further the hot water in the heating furnace body water cooled furnace wall.The utility model both can be used for cooking, and the hot water that has heated again in the water cooled furnace wall of body of heater is used for heating.The distance that in stove, flows after the stove fuel combustion, big with the heat exchange area of water cooled furnace wall, the heat that is produced after the fuel combustion can be utilized fully, fuel savings has improved the thermal efficiency.At the non-heating season joint, mainly use upper combustion chamber of the present utility model to heat up water and cook.Because upper combustion chamber's capacity is little, can add a spot of fuel, burned flame directly flows out from the fireworks outlet.Go up the size of the fire sealing cover aperture of installing by the outlet of control water-cooled head plate fireworks, control fireworks and upwards flow or return the flow that fire flows downwards, reach the burning velocity of control fuel and the size of firepower.In the time of need banking up a fire, the control fire sealing cover is realized suitable fire-sealing time and the temperature of banking up a fire in the size of water-cooled head plate fireworks outlet.The fuel of the utility model practicality can use coal, also can use agricultural crop straw or agricultural crop straw briquetting.The utility model is not only rational in infrastructure, and heat exchange area is big in the stove, thermal efficiency height, and can use fire coal or agricultural crop straw to act as a fuel, and can bank up a fire easily, easy to operate, fuel savings.

The specific embodiment
A kind of household cooking and warming stove that uses fire coal or stalk fuel, as Fig. 1, Fig. 2, shown in Figure 3, comprise body of heater with water cooled furnace wall, ventilation deashing chamber, fire grate, burner hearth and flue are being set in body of heater, the bottom that has water cooled furnace wall 8 and the water-cooled head plate 6 that has the fireworks outlet behind the water cooled furnace wall of charge door 1 and the burner hearth that top is provided with exhaust opening 9 and be positioned at both sides in burner hearth is provided with that the water-cooled sidewall 17 that returns fiery passage is common to constitute combustion chambers, in the combustion chamber lower fire grating 16 above upper fire-grating 4 is being set, the combustion chamber is divided into upper combustion chamber 5 and lower combustion chamber 3.In the fireworks outlet of water-cooled head plate 6, fire sealing cover 7 is installed.Ventilation deashing chamber 15 is being set below lower fire grating 16.Charge door 1 is for stretching out outside the body of heater, acclivitous tubbiness charge door, the hinged gallery ports 2 that are installed with in the upper shed of charge door 1, charge door 1 at the opening on the body water-cooling wall between upper combustion chamber 5 and lower combustion chamber 3.By charge door 1 can be on the upper fire-grating 4 of upper combustion chamber 5 refuelling, also can be on the lower fire grating 16 of lower combustion chamber 3 refuelling.Spacing between upper fire-grating 4 fire bars is greater than the spacing between lower fire grating 16 fire bars.The fire bars of upper fire-grating 4 has the spacing of broad, is particularly suitable for adding stalk fuel on upper fire-grating 4.If need on upper fire-grating 4, add fire coal the time, then must on upper fire-grating 4, install fire bars spacing less fire grate.The exhaust opening 9 of water cooled furnace wall 8 is connecting flue gas heat absorption smoke box behind the burner hearth, the heat absorption smoke box is separated into heat-exchanging chamber 10 and updraught flue 14 for the waterbaffle 13 that is connected as a single entity with water cooled furnace wall, the body of heater both sides smoke box that will absorb heat, wherein the exhaust gases passes mouth of waterbaffle 13 bottoms setting is communicated with heat-exchanging chamber 10 and updraught flue 14, water pipe 11 uniform in heat-exchanging chamber 10 is communicated with water cooled furnace wall, body of heater both sides, and symmetrical water pipe 11 is communicated with between can also will arranging by connection water pipe 12 between the two uniform drainpipes 11.The heat-absorbing water pipe group of being made up of water pipe 11 and connection water pipe 12 has increased the heat exchange area of flue gas in heat-exchanging chamber.The heat of flue gas carries out heat exchange in heat-exchanging chamber 10 after the flue gas port of waterbaffle 13 bottoms enters updraught flue 14, further carries out heat exchange with the water cooled furnace wall, makes full use of the waste heat in the flue gas, has further improved the thermal efficiency.
