First, the reason for not operating a burner, the gas pressure is lower than the low voltage protection switch. On Check gas valves are open, if there is gas in the tank. 2, the gas pressure is higher than the pressure protection switch. Shut off valve, and check the pressure reducing valve or regulator box has failed. 3, steam china supplier fire tube burner water level is too low, there is very low interlock. Boiler water level observation, grasp the true level, after manual Sheung Shui to eliminate problems. 4, gas steam boiler pressure is higher than the starting pressure. Natural gas and other boiler pressure to reduce the pressure to start, you can start properly. 5, but the leak valve block. Manifolds may be a leak. 6, the burner or blacksmith ion probe no reliable ground line. Second, the matter before the gas boiler operation Note 1, gas steam boiler before ignition must conduct a comprehensive examination, including the burner and related accessories and pipes are complete good, the operation is flexible. Before the water is not required to close the drain valve, open a safety valve, allowing air furnace can be discharged. After all the examination was normal, boiler before ignition Sheung Shui, Sheung Shui to drum should be the normal water level, turn on any air, flue baffle. Start the blower, the flue of the furnace and vent purge, purge time is not less than 30 seconds, and then start the ignition burner. 2, the treated water injected into the gas boiler, the water temperature should not exceed 40 ℃, when the pot water level reaches the lowest level, i.e. the inlet valve closed, to observe whether the water level is lowered. After firing the pot should always pay attention to the water level, the water level will rise as a result of exceeding the maximum safe water level can be heated sewage. 3, when the gas and steam emitting steam boiler the safety valve opens, the safety valve should be closed, when the boost to 0.2 ~ 0.3MPa, inspection manhole discharge valve leaks and the like.
Boiler Fan analytical work principle and common installation and maintenance methods? Boiler Fan works: it relies on mechanical energy input, increase the gas pressure of the gas sent to the mechanical side by side, it is a slave fluid machine. Works in induced draft fan and the compressor turbine is substantially the same, but due to the low gas flow rate, little change in pressure, the gas is generally not necessary to consider the change in specific volume, i.e., the process gas as incompressible fluid. Boiler Fan application to blower widely used in factories, mines, tunnel ventilation, cooling towers, vehicles, ships and buildings, dust emission and cooling; the china supplier fire tube burner and industrial furnace ventilation and the air; an air conditioning equipment and household appliances cooling and ventilation equipment; grain drying and should select; tunnel and hovercraft air source and the pneumatic propulsion.
Chongyang County, Hubei Province since the second half of 2015 to carry out the work out of small coal-fired china supplier fire tube burners, non-New 20 tons of steam / hour and below the coal-fired boilers, the full implementation of small coal-fired boilers out of work, with environmental protection, Development and Reform Commission, by letter and other related sector wages, work to strengthen the efforts to promote thorough investigation of strict control to ensure that the county's non-compliance of small coal-fired boilers have all been eliminated remediation.

It is understood that, recently, joint quality supervision department of Chongyang County People's Government of Hubei Province, a special selection of personnel to carry out "looking back" activities for the phasing out small coal-fired boilers, special personnel division of responsibilities is based on special teams, focus on examination paper, under chemicals, wine, agriculture, and several other sectors and enterprises of boiler equipment, non-small coal-fired boilers happen "resurgence" phenomenon.
Rated supply temperature and return water temperature gas hot water boiler, mostly marked in accordance with the standard GB3166-82. The actual boiler for hot water, return water temperature according to weather conditions during the heating and the heating requirements of the decision. The adjustment method for heating in winter, there is a change of mass of the boiler water temperature regulation, but also the amount of change of the boiler flow rate adjustment cycle; therefore, the hot water boiler water temperature can change according to need.
