Description
Technical field
The present invention relates to a kind of burner, and in particular to a kind of full pre-mix condensing steam generator.
Background technology
Steam generator refers to the burner for water being heated as using fuel steam, natural gas, liquefied gas and artificial coal gas
As a kind of environmental clean high-grade energy, hardly sulfur-bearing, dust and other harmful substances, harmful substance caused by burning
Less than other fossil fuels, it can fundamentally improve environmental quality.But current gas steam generator is all in burning
During by blower fan supply air, this atmospheric burning type mode flame propagation velocity is slower, and the thermal efficiency is not high, there is more nitrogen
The discharge of oxide, is unfavorable for environmental protection.
The content of the invention
The invention provides a kind of full pre-mix condensing steam generator, is led to solving combustion process existing for prior art
Air cause efficiency of combustion low and not environmentally the problem of.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of full pre-mix condensing steam generator, including housing, burning cylinder, secondary heat exchanger and deputy tank, burning cylinder,
Secondary heat exchanger and deputy tank are built in the frame in housing, and for secondary heat exchanger below burning cylinder, combustion gas passes through ratio
Example valve communicated with the fuel gas inlet of premix chamber, air is communicated by air cleaner with the air intake of premix chamber, premix chamber and
Fans entrance is connected, and fan outlet is connected with blender, and gaseous mixture enters in combustion barrel body the snakelike heat exchange coil put after lighting
In, a filling pipe leads to combustion barrel body phase, and steam outlet pipe is set at the top of burning cylinder, the snakelike heat exchange disk in the cylinder that burns
Pipe outlet is communicated by flue gas delivery line with secondary heat exchanger, and a upper hose passes through two magnetic valves and secondary heat exchange in parallel
Serpentine coil in device communicates, and the serpentine coil outlet in secondary heat exchanger communicates with burning cylinder water route, the top of deputy tank
Communicated respectively with filling pipe at the top and bottom of burning cylinder with bottom, three level sensors built in deputy tank are to sense combustion barrel
Internal high, normal, basic third gear water level, sets pressure sensor in deputy tank, three level sensors and pressure sensor respectively with control
Panel processed is connected.
Above-mentioned housing bottom sets some road wheels.
Present invention burning cylinder uses full premix combustion structure, while high-temperature flue gas is condensed using secondary heat exchanger
Heat exchange, combustion gas are sufficiently mixed before burner with enough air, flame propagation speed, excess air coefficient very little,
Ignition temperature is very high, effectively reduces the discharge of pollutant such as nitrogen oxides and carbon monoxide.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.

The air intake of chamber communicates, and premix chamber is connected with the entrance of blower fan 8, and the outlet of blower fan 8 is connected with blender 9, the outlet of blender 9 mixing
Gas enters in the snakelike heat exchange coil 10 built in combustion barrel body 2 after lighting, and filling pipe 15 communicates with burning cylinder 2, and burn cylinder 2
Top sets steam outlet pipe 11, and the outlet of snakelike heat exchange coil 10 in the cylinder 2 that burns is changed by flue gas delivery line 14 with secondary
Hot device 3 is communicated, and upper hose 12 is communicated by two magnetic valves 13 in parallel with the serpentine coil in secondary heat exchanger 3, secondary to change
Serpentine coil outlet in hot device 3 communicates with smoke-exhaust pipeline 16, the top and bottom of deputy tank 4 respectively with the top of burning cylinder 2
Communicated with filling pipe 15, three level sensors 17 built in deputy tank 4 are to sense high, normal, basic third gear water level, secondary water in combustion barrel body
Pressure sensor 18 is set in case 4, and three level sensors 17 and pressure sensor 18 are connected with control panel 19 respectively, housing
1 bottom sets some road wheels 20.
Present invention burning cylinder uses full premix combustion structure, while high-temperature flue gas is condensed using secondary heat exchanger
Heat exchange, combustion gas are sufficiently mixed before burner with enough air, flame propagation speed, excess air coefficient very little,
Ignition temperature is very high, effectively reduces the discharge of pollutant such as nitrogen oxides and carbon monoxide.
