LSS type of fuel (gas) boiler for combustion quick vertical bent tube boilers. Fuel from the outside air into the burner through automatic adjustment, automatic ignition function generates high-temperature flame, the stove top secret drains bile into the inside of the furnace inside, in the lower furnace into the furnace with mezzanine close to drain off 180 ° room, then fold the lower part of the furnace flue port 180 ° into the cylinder fins layer packaging layer, between the ribs after the flue gas leaving the heat transfer from the boiler to the chimney flue port upper atmosphere. Boilers with good technical performance burners, combustion using automatic ratio adjustment automatically adjusts the water supply, the program start and stop, automatic operation and other advanced technologies, and has low water level alarm and low water levels, high steam pressure, turn off automatic protection function . The boiler has a compact, safe, reliable, simple, quick to install, less pollution, low noise, high efficiency. CLSS type of fuel (gas) boiler for combustion curved vertical pipe pressure hot water boilers. Using curved pipes bias structure, ejected from the burner flame temperature furnace first flush pipe tobacco, and then enter the secondary return after turning smoke chamber composed by curved pipes, through the chimney into the atmosphere. Boiler with removable mosaic structure, the boiler maintenance is extremely convenient. Boilers with good technical performance burners, combustion using automatic ratio adjustment automatically adjusts the water supply, the program start and stop, automatic operation and other advanced technologies, and has low water level alarm and low water levels, high steam pressure, turn off automatic protection function . The boiler has a compact, safe, reliable, simple, quick to install, less pollution, low noise, high efficiency.
