In order to meet the standard gas steam water tube boiler advantages size water impurities must be controlled gas steam boiler is the use of a steam boiler heated by a gas burner. Vertical steam boiler combustion engine underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency of the boiler, reduce user costs; horizontal steam boiler shell type three return all wet back downstream pyrotechnic pipe structure, large combustion flame in the combustion chamber a slight positive pressure, fully extended, low combustion heat load, the high heat of combustion efficiency, effectively reducing the exhaust gas temperature, energy saving, more economical, and a waveform furnace threaded pipe structure, i.e. increase the strength of the heat absorption of the boiler, but also to meet the needs of thermal expansion of the heating surface, scientific and rational, and durable. In order to meet the standard gas steam boiler water, impurities in the water must be controlled within a range. Salt boiler, boiler water and a high alkali content, sludge and loose bottom sediments deposited, are necessary. This process is called sewage. If these deposits are not discharged, it will affect the quality of steam, but also to the boiler wall fouling, adverse water cycle, affecting the normal operation of the boiler. So we have to cut the formation of impurities in the boiler, in order to ensure the salinity of water in the gas steam boiler within the allowable range, which is the purpose of wastewater. When the gas steam boiler water level slightly lower load, the higher the vapor pressure, should better sewage. Gas steam boiler circulating water slowly at a low load, likely to cause the accumulation of dirt in the bottom of the drum and the fluid collection tank, and in the high vapor pressure, large sewage flow, dirt easily discharged. Therefore, when the water level in the boiler blowdown and drainage should be maintained at 60% of the operation, when sewage must designate personnel to closely monitor changes in the water level to prevent water shortages. Drain valve open should be short intermittently, the speed of each closed sewage, sludge fouling will cause interference, therefore repeated, by inhalation sediment quickly converge to the sewage outlet, then the concentrative discharge. Control the time, not too long, the sewage of time must exceed 30S. When the discharge time is too long, dirt content of the boiler water will gradually reduce the effect of variation not only sewage, emissions will increase, not only a waste of energy, but also affect boiler the water cycle, and even destroy the furnace tube. Observation of the given row Expander steam outlet, the discharge of sewage, drainage temperature always touch the fixed discharge outlet and check the container to determine if the drain valve is fully closed. If the valve leaks at the debris card, you can re-open and close quickly. If the valve due to wear and difficult to close, monitoring should be strengthened.
Heat efficiency can reach 103% to 108%, relative to conventional gas water tube boiler advantages size energy saving effect can be increased by about 30%. Boiler also joined the premix, FGR and other international advanced combustion technology, more natural gas fuel combustion, while reducing the demand for air, no excess air, improve leak flue gas, flue gas condensation into the early stage, in order to further combustion efficiency, boiler heat transfer area, high thermal efficiency, low exhaust gas temperature can be 50 ℃, with reduced heat loss.
10,000 square meters of heating area required much gas heating water tube boiler advantages size? Gradually into the late autumn, the upcoming heating season, many companies and many units began considering the purchase of heating boilers, but many people are wondering heating boiler heating area is how much their heating area such as require much heating boilers and the like the problem, the following small series to take you look at an area of 10,000 square meters of heating needs with how much gas heating boiler. There are more factors to this problem can not be generalized. First look at the boiler in the area, under normal circumstances, 10000 (all aspects of altitude, temperature, and other areas to maintain normal) square meters of heating area, about 2 tons of heating boilers is possible, but with the altitude, the temperature , the difference of pressure, boiler heating area of the same tonnage will naturally vary. Therefore, if this is the case, corresponding to the tonnage research final selection. In addition, the use of boiler depends on the layout of the building site, specific hardware facilities and conditions. If these conditions are convenient, then, the demand for tonnage is naturally slightly larger than a standard like to do so in order to respond to exceptional circumstances, the boiler running overload condition occurs. If that condition is not convenient, then a combination of factors need to be considered would be much tonnage of the boiler will naturally be larger than normal. Finally, look at how its own boiler thermal efficiency, this is basically according to the contrast between the brand, the high thermal efficiency of the boiler, heating area in unit time it will naturally be much higher, then select the tonnage factors hampered naturally many will be reduced. In short, we need about 2 tons of gas heating boiler heating area of 10,000 square meters under normal circumstances, if there are special circumstances like the above or other areas, the need to analyze specific issues.
