hot sale 2 ton natural gas fired steam boiler
Henan newly installed gas boiler 1 what kind of work before starting. Henan newly installed gas boiler before starting what should be done? These include: the tightness of (1) hydrostatic test (overpressure test), test pressure member. (2) Trial and various auxiliary electric door damper check. (3) oven. Water inside wall of the furnace and gas water boiler tubes Henan removed. (4) cooking stove and pickling. Remove grease deposits in the evaporator heating surface system, rust, oxide scale and corrosion products, and other like with lye and acid. (5) furnace aerodynamic field test. (6) flushing pipe. Henan boiler with gas flushing a self-generated steam, the second steam duct heteroaryl residue. (7) check security doors. 2. Henan gas boiler before start time and temperature of water on what regulations? why? Water speed before the start of Henan gas boiler should not be excessive, winter generally less than 4h, other seasons 2 ~ 3h, especially in the beginning of the water should be slow. Cold boiler water temperature is generally not more than 100 ℃, so that the temperature difference between the feedwater entering the drum drum wall temperature is not more than 40 ℃. Henan not completely cooled gas boiler drum water temperature, mutatis mutandis, wall temperatures, generally the difference should be controlled within 40 ℃, it should slow down or speed water. The reasons are: (1) Since the thick-walled drum, slow expansion, the wall of the tube is connected to the drum wall is thin, expanded rapidly. If the inlet water temperature is too high or too fast, uneven expansion will cause the weld cracks occur, resulting in damage to the equipment. (2) when the water supply enters the drum, the drum is always in contact with the first half wall, if the water temperature and the drum wall temperature difference is too large, the influent fast speed, on the drum, the lower wall, the inner and outer wall inter will have a greater expansion difference, caused a large drum to additional stress, causing deformation of the drum, when severe cracks.
Wuhan Port District Social Welfare Institute (apartments for the elderly) is invested by the government pension services, with a total construction area of 38,000 square meters, 532 beds, mainly adopt destitute persons, social support on behalf of the elderly. Hope to provide welfare to the elderly year-round 24-hour hot water, the original boiler equipment can not meet this demand, therefore, require additional purchase orphanage hot water boiler. After much investigation, in cooperation with the welfare determined fast boiler, provides three integrally condensing gas hot water boiler (WNS1.4-1.0 / 95/70-Y.Q) by a fast boiler.
The oil and gas water tube boiler produced by ZBG is a fast-assembling boiler that can be used in bread factories to steam supply, hot water supply, heating and other uses. Moreover, the boiler has a small footprint, which reduces the investment in the boiler house, and the boiler is highly automated and reduces labor costs.
0.5 tons gas boiler introduced: 0.5 tons of gas boiler Description: 0.5 tons of gas boiler imported burner, automatic programmed control, automatic purge blower, electronic auto-ignition, spontaneous combustion and gas, (air) automatically adjusting the ratio of wind oil good atomization, combustion, low NOX, energy saving and environmental protection. Under normal circumstances, when the boiler steam pressure reaches the set value, the burner combustion is automatically stopped, when the steam pressure is below the set value, the burner is automatically started. When the abnormal phenomenon of the fuel, air intake, fault lights, the output sequencer will immediately stop the fuel, burner shut down automatically.
