Our demand for environmentally friendly and out of the hotel itself, very high environmental performance requirements for boilers, party fast products fully meet our needs, the index after testing are in line with the relevant provisions of the State; with the outside atmospheric pressure remains stable sufficiently improved security index boiler, eliminating our worries. --customer feedback

Fuel gas-fired boiler fuel gas-fired boiler product presentation is different from coal-fired boilers, which requires the use of a burner fuel is injected into the boiler furnace using a combustion chamber without the use of fire grate facilities. Because not produce fuel ash after burning fuel gas-fired boiler, fuel gas-fired boiler so without slagging facilities. Oil injected into the furnace, if the gas and air mixture within a certain range, or turned off, it is easy to explode. Therefore, fuel gas-fired boiler combustion required to adopt automation and control systems. Fuel gas boiler compact, small boiler and ventilation, water supply, control and auxiliary equipment are arranged on a distribution box, it may also be assembled and medium-sized factory. Fuel gas-fired boiler safety valve installation points introduce fuel gas-fired boiler safety valve needs to be installed in the correct installation steps, in order to avoid mistakes, resulting in what needs to pay attention to danger, fuel gas-fired boiler safety valve installed it? Here, I introduce: 1 fuel gas boiler safety valve should prevent the lever means and movement of the self-weight limit leverage deviant guide tube, a spring safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly . 2. Rated to 0.5t h evaporation boiler fuel gas /, at least two safety valves installed; Rated evaporation 0.5t h or less fuel gas boiler /, mounted on at least a safety valve. The separable exit of the economizer, steam superheater outlet of the safety valve must be installed. 3. Fuel gas-fired boiler safety valve to the boiler tubes, cross-sectional area should not be less than the import safety valve cross-sectional area. If several valves installed together with a short tube directly connected to the drum, short tube passage area not less than 1.25 times the area of ​​all the exhaust valve. 4. Fuel gas boiler safety valve should be installed vertically in the boiler drum, header high position. Between the valve and the drum or header, not equipped with access to the steam outlet pipe and the valve. 5. For rated steam pressure less than or equal to 3.82MPa boiler safety valve throat diameter of not less than 25mm; the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20mm. 6. Fuel gas-fired boiler safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust. Safety valve exhaust pipe at the bottom should be fitted to the safe location of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve.

Steam Gas Gas Desulfurization to achieve excellent results steam oven gas steam oven must sample tests, the thermal conductivity was measured quality of appearance, flash point, viscosity, acid, water, and carbon residue, provided with heat transfer fluids plant proof mass It is consistent with the book, but also provide the basis for future changes in the operation of medium quality monitoring. Means passing the tests of the gas-steam heat transfer fluids using pumps to transfer fluids within the furnace and the injection of hot expander. When pumps heat transfer fluid to the injection system, should check again the furnace, heating equipment, piping system drain valve, drain valve is closed, in order to avoid loss of heat transfer fluids. While the exhaust pipe and the valve opening on the furnace one by one, to exclude air, until a closed gas steam flows. It stops when the oil level gauge appears on the expander injection heat transfer fluids, and then start the circulation pump, for circulating cold. Existing gas steam oven dry dust, do not meet wet desulphurization process of flue gas CWS humidity, water vapor in the flue gas as coal-water slurry up to 36%, some as high as 40% or more water content of coal-water slurry, If we consider only the dust and sulfur dioxide that is not enough. Arts gas steam boiler company after multi-party experts to study, test, develop a dusting product, the successful use of coal-water slurry plenty of water in the flue gas as a carrier, by cooling, reducing condensation, dust and sulfur dioxide capture down, to achieve excellent results gas desulfurization steam oven. The effect of dust reaching the user's satisfaction. Gas welding gas steam oven must be operated by welders holding boiler and pressure vessel certification of welders. Welding dimensions meet the design drawings and process documents, bead height is not less than the base material, the base material with a smooth transition. Gas fuel gas steam oven weld and heat affected zone no cracks, holes, craters and slag. Weld undercut hole deeper than 0.5mm, the total length (the sum of both) is not more than 1/4 of the circumference of the tube, and not more than 40mm. Construction of gas steam oven strict compliance with welding procedures and other relevant standards and regulations, and make construction records welded to record the record.

The oil and gas water tube boilers produced by ZBG have a thermal efficiency of up to 98%, and use FGR flue gas recirculation technology and staged combustion technology to achieve low nitrogen emissions from boilers with NOx emissions below 30 mg/Nm³. The highly automated operation of the boiler, high safety performance, low boiler installation investment, and low operating costs make it a very popular oil and gas boiler in foreign markets.
