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 that when burning generates
Less than other fossil fuels, it can fundamentally improve environmental quality.But current gas steam generator is all in burning
Air is supplied by wind turbine in the process, 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.
Utility model content
The utility model provides a kind of full pre-mix condensing steam generator, of the existing technology burned to solve
Journey blowing air cause efficiency of combustion low and not environmentally the problem of.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of full pre-mix condensing steam generator, including shell, burning cylinder, secondary heat exchanger and deputy tank, burning
Cylinder, secondary heat exchanger and deputy tank are built in the rack in shell, and secondary heat exchanger is located at below burning cylinder, and combustion gas is logical
It crosses proportioning valve to communicate with the fuel gas inlet of premix chamber, air is communicated by air cleaner with the air intake of premix chamber, premix
Chamber is connected with fans entrance, and fan outlet is connected with mixer, and gaseous mixture enters the snakelike heat exchange set in combustion barrel body after lighting
In coil pipe, a water supply pipe is communicated with burning cylinder, and steam outlet pipe is arranged at the top of burning cylinder, snakelike changing in the cylinder that burns
Hot coil outlet communicated with secondary heat exchanger by flue gas delivery line, a upper hose by two solenoid valves in parallel with it is secondary
Serpentine coil in heat exchanger communicates, and the serpentine coil outlet in secondary heat exchanger is communicated with burning cylinder water route, deputy tank
Top and bottom are communicated with water supply pipe at the top and bottom of burning cylinder respectively, and three water level sensors built in deputy tank are to incude combustion
High, normal, basic third gear water level in cylinder is burnt, pressure sensor, three water level sensors and pressure sensor difference are set in deputy tank
It is connected with control panel.
Several traveling wheels are arranged in above-mentioned housing bottom.
The utility model burns cylinder using full premix combustion structure, while being carried out to high-temperature flue gas using secondary heat exchanger
Condensing heat-exchange, combustion gas are sufficiently mixed before burner with enough air, and flame propagation speed, excess air coefficient is very
Small, ignition temperature is very high, effectively reduces the discharge of pollutant such as nitrogen oxides and carbon monoxide.
