Description
Technical field
The utility model relates to a kind of boiler, specifically a kind of energy-efficient methane boiler.
Background technology
The existing hot-water boiler of China or steam boiler, what mainly adopt is coal-burning boiler.When environmental requirement and CO2 emission limit more and more stricter, coal-burning boiler has more and more been difficult to meet require that of environmental protection.And the major gas of gas fired-boiler comprises natural gas and coal gas, corresponding what use in gas fired-boiler is exactly neat gas burner and gas burner two type.Neat gas burner is mostly multiple gun air inlet flat flow structure, and natural air gun is placed in the air duct of air register.And gas burner is lower because of coal gas caloric value, difficulty of catching fire, therefore the passage combustion of being everlasting red-hot, then spray in combustion chamber.
Existing gas fired-boiler Problems existing is that gas consumption is large, and the economy of use is not high.
Utility model content
The purpose of this utility model is just to provide a kind of energy-efficient methane boiler, to solve the problem that gas consumption is large and its usage economy is not high that existing gas fired-boiler exists.
The utility model is achieved in that a kind of energy-efficient methane boiler, and in body of heater, be provided with the double-deck flue of the semicircle cover shell-type of uncovered, the closed at both ends in bottom, described double-deck flue forms the water-jacket space of sealing; The two ends inner layer wall of described flue is connected with some heat absorption combs, the outer wall of described flue is connected to the water inlet pipe stretching out described body of heater and steam/heat water discharge pipe, the bottom of described flue is provided with infrared burner; Infrared burner is placed with some ceramic wafers at the end face of burner body, is connected to combustion gas mixing pipe in the bottom of described burner body, is provided with air inlet and gas inlet pipe in the front portion of described combustion gas mixing pipe.
Described air inlet and gas inlet pipe are positioned at the fire door place of described body of heater forward lower part.
The utility model uses specially designed case type flue splendid attire heating water, the some heat absorption combs of cross-under in flue, and use infrared burner to heat, like this, boiler heating surface can be made to increase on the one hand, thermal conversion efficiency improves, the use of infrared burner on the other hand, on the basis of improving the efficiency of heating surface, also achieve energy-saving combustion, reduce the discharge of pollutant.
Infrared burner adopts porous ceramic plate as burning jamb, the combustion gas with certain pressure sprays gas-flow with very large speed to injector porch through nozzle, and cause certain pressure at the suction inlet place of injector, thus once can suck burning air capacity used, at the mixing section of injector, because respective speed, concentration and proportion are different, phase counterdiffusion also mixes the air of combustion gas and suction gradually.When gas uniform flow into burner body after, meet incendiary source on the surface of the porous ceramic plate of burner body and burn, finally at the crimson look that porous ceramic plate surface presentation is scorching hot, now surface temperature can reach 800-900 DEG C, combustion zone temperature can reach 1100-1400 DEG C, gives off the infrared ray that wavelength is 2-4 micron.
Due to infrared burner burn time and air fully premixed, guarantee that burning completely, thus reduce the discharge of pollutant, the infrared radiation that during burning, porous ceramic plate sends has stronger penetration power, and hydrone can be excited to resonate, therefore, even heat can be penetrated in the heating water in flue, improve thermal conversion efficiency.The porous ceramic plate be made up of refractory ceramic material forms infrared radiation panel, when flame combustion, flame is transformed into infrared ray, accelerates the thermal histories of flue.Due to infrared radiation transmission, thus the performance of gas fired-boiler is very significantly improved, makes the energy-saving efficiency of gas fired-boiler reach more than 20%.
The utility model has energy-efficient, low stain, economical and practical, the advantage such as use safety and simple installation, particularly can biogas as fuel, therefore the outskirts of a town and the rural area that widely use biogas is applicable to, for industrial and agricultural production enterprise provides steam or the hot water of clean, high heat, meet the needs of production.
The utility model also can use the various combustion gas such as natural gas, liquefied gas, shale gas or coal gas.
