Description
Technical field
The utility model belongs to the domestic boiler that uses solid fuel, the particularly double grate radiator of cooking a meal of easily banking up a fire.
Background technology
In northern China winter, it is coal-burning boiler that vast urban and rural residents use more domestic heating, cooking boiler for dual purpose, its structure is that the wall of body of heater adopts the water jacket 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 water jacket furnace wall.This coal-burning boiler not only can be used to cook, and the hot water in the heated water jacket furnace wall can be for domestic waters such as heating, bathings.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, water in the coal fuel heating cooking-heating dual-purpose stove water jacket of sufficient amount can be housed in burner hearth, just can make the hot water temperature in the heating water cooled furnace wall and the amount of hot water reach the requirement of indoor heating, but save at non-heating season, use this cooking-heating dual-purpose stove to cook and supply domestic water, because the burner hearth of cooking-heating dual-purpose stove is bigger, it is many to consume fuel, causes the waste of the energy.The heat exchange area of the flame of fired coal combustion in stove is little, and the thermal efficiency is low.In addition, use cooking-heating dual-purpose stove need bank up a fire night in heating season, this cooking-heating dual-purpose stove device of not banking up a fire, and adopt the foam coal to bank up a fire.Tight if banked up a fire, fire coal 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.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 use double grate radiator of cooking a meal of easily banking up a fire, and not only it is rational in infrastructure, and heat exchange area is big in the stove, thermal efficiency height, and the fuel band that can be fit to use is many, 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 double grate easily seals the household cooking and warming stove, 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, in burner hearth, have the water cooled furnace wall of charge door and the water cooled furnace wall of both sides and be provided with the waterbaffle formation combustion chamber of returning fiery passage, in the fireworks outlet of water-cooled head plate, fire sealing cover is installed with water-cooled head plate that has the fireworks outlet and bottom.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.Between waterbaffle and furnace water cooling rear wall, be provided with fireworks channel, exhaust opening be set in the back upper place of burner hearth.
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.Flame in the combustion chamber fuel combustion can upwards flow by the fireworks channel of fiery passage between waterbaffle and furnace water cooling rear wall that return of outlet of the fireworks on the water-cooled head plate and lower combustion chamber bottom, both can be used for cooking, the hot water that has heated again in the water cooled furnace wall of body of heater is used for heating.The distance that fireworks after the burning flow in stove, big with the heat exchange area of water cooled furnace wall, the heat that fuel combustion is produced can be utilized fully, and 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 the capacity of upper combustion chamber is little, can add a spot of fuel, burned flame directly flows out for the hot water of cooking and heat the water cooled furnace wall from the fireworks outlet and gets final product for domestic water.Go up the aperture size of the fire sealing cover 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 exports the flow direction of the size of aperture with the control fireworks at the water-cooled head plate fireworks, to realize suitable fire-sealing time and the temperature of banking up a fire.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 the heat exchange area of water cooled furnace wall is big in the stove, thermal efficiency height, and also the fuel band that can be fit to use is many, can bank up a fire easily, and easy to operate, fuel savings.
