Natural gas steam boiler opening pressure constant, explosion-proof door cover double sealing structure, tight sealing. Inspection door disassembly and restoration is simple, the personnel requirements are not high. Environmental natural gas boiler have large pressure relief area and are safer to use. Pressure relief is safe, the hot air will not hurt people. The series of steam boilers are tightly sealed, factory air leakage test, do not leak smoke; The welding of smoke box adopts surface detection to prevent gas leakage, condensate water and corrosion of skin.
When running from cold state to hot state, this series of gas-fired boilers can be freely telescopic, without constrained stress and safer. The insulation material is made of high quality refractory fiber. The skin temperature is low and the surface heat dissipation loss is small. Gas steam boiler adopts large furnace full waveform furnace design, matching reasonable low nitrogen combustion machine flame, fully reduce the furnace flame high temperature zone combustion temperature, effectively control the increase of NOx concentration, completely meet the requirements of low nitrogen emissions.
Natural gas steam boiler using screw heat transfer calculation, screw disturbance design principle, through three-dimensional animation simulation, design high efficiency heat transfer resistance small screw smoke pipe. And the use of high quality seamless steel pipe, so that the heat transfer is good, friction resistance is small, prolong the service life. Environmental natural gas boiler is equipped with invisible FGR flue gas external circulation configuration, which can meet the emission standard of 30mg low nitrogen burner. The boiler is equipped with Siemens solenoid valve, and the flue gas flow recirculation rate is controlled according to the combustion condition of the burner itself, so as to achieve the ideal low nitrogen emission below 30mg.
All parts of this series steam boiler adopt laser cutting and cold working process, and its sealing plate is made of ND steel. The low temperature corrosion resistant spiral finned tube is used to increase the heat transfer area in the limited space, fully absorb the tail flue gas, reduce the exhaust temperature and improve the thermal efficiency of the boiler. The product structure of this series of boilers is built in, which can completely not occupy the space area of the boiler room, and has a wide range of applications. The design concept of the front smoke box adopts the two-layer structure of double-layer and double-set built-in labyrinth insulation layer and heat-resistant layer, which has good thermal insulation performance. And the smoke box panel and the smoke box cover are made of integral Q245R boiler steel plate. The steel plate is cut by laser numerical control technology, which has small deformation, high assembly precision and good welding forming. The main opening is convenient, sealing is tight, convenient for the user to check and maintain.
Environmental natural gas boiler outer surface of the body is made of aluminum silicate felt and bread with good heat preservation performance. Boiler frame is made of high quality cold drawn after nc folding bed, and becomes “concave” strong compression ability frame connected to the front and rear panel compound, its packaging panel for rectangular inlay card into the assembly, the four corners are opened in form since the tapping hole, and uses the 304 decorative cover seal, convenient maintenance, overall modelling beautiful, novel, small heat loss, improve thermal efficiency of boiler.
