Description
Technical field
The utility model is related to a kind of burners, and in particular to a kind of full premix heating stove.
Background technology
Natural gas, liquefied gas and coal gas as a kind of environmental clean high-grade energy, hardly sulfur-bearing, dust and other have
Evil substance generates carbon dioxide when burning and is less than other fossil fuels, causes greenhouse effects relatively low, can fundamentally improve environment
Quality.But current gas heating stove is all to supply air, this combustion system flame by wind turbine during burning
Spread speed is slower, and excess air coefficient is bigger than normal, and ignition temperature is not high, leads to the discharge for having more nitrogen oxides, is unfavorable for ring
It protects.
Utility model content
The utility model provides a kind of full premix heating stove, is led with solving combustion process blowing air of the existing technology
Cause efficiency of combustion it is low and not environmentally the problem of.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of full premix heating stove, including shell, burner block and secondary heat exchanger, in burner block and secondary heat exchanger
It is placed on the supporting rack in shell, fuel gas pipeline is communicated by proportioning valve with the fuel gas inlet of premix chamber, and air passes through air filter
Clear device is communicated with the air intake of premix chamber, and premix chamber is connected with fans entrance, and fan outlet is connected with mixer, and mixer goes out
Mouthful communicated with burner block, burner block top setting igniter and overheat protector, the exhanst gas outlet of burner block with it is secondary
Heat exchanger is connected, and the chimney at the top of secondary heat exchanger is pierced by shell upwards, serpentine coil heat exchanger, upper hose built in burner block
It is connected respectively with serpentine coil heat exchanger with return pipe, the upper water branch pipe of upper hose is connected with secondary heat exchanger, secondary heat exchanger
Return water entered in return pipe by threeway, temperature sensor is set on return pipe, burner block bottom is arranged drainpipe, two
Drip pipe is arranged in secondary exchanger base, and exhaust pipe is arranged at the top of burner block.
Filter is set on above-mentioned fuel gas pipeline, air cleaner is set on air pipe line.
Above-mentioned serpentine coil heat exchanger is coil heat exchanger.
