low emission gas fired hot water boiler

low emission gas fired hot water boiler

Oil boiler greatly reducing the fuel consumption of the fuel for the internal combustion quick three-pass horizontal fire tube boiler. Furnace using offset wet back structure, high temperature flue gas flushing sequentially the second and third return pipe tobacco, and then discharged into the atmosphere through the chimney of the smoke chamber. Activities before and after the boiler is equipped with smoke cover, the boiler easy maintenance. Oil-fired boiler chain greatly boiler burner arranged good technical performance, the use of automatic combustion ratio adjustment, automatically adjust the water supply, the program start and stop, automatic operation through the convection heating surface of the heat exchanger area of ​​the boiler body growth or using convection heat transfer coefficient increases method, oil-fired boiler exhaust gas temperature to reduce the chain; 2, increase of the tail heating surface. Before explaining the purpose of the method is to efficiently recover the sensible heat and latent heat from exhaust gas, is the next to achieve the above object generally speaking processes: conventional boiler, the exhaust gas temperature is usually 160 ~ 250 ℃, the water in the flue gas still overheated vapor, liquid water is not easy to form a cold-releasing latent heat of vaporization. Well known, the thermal efficiency of the boiler fuel is a low calorific value calculated without considering heat loss of latent heat of vaporization of the high heating value fuel. Reducing the fuel consumption of a conventional boiler thermal efficiency is thereby substantially only 87% to 91%. And condensing boiler, the flue gas temperature is reduced to the chain 50 ~ 70 ℃, thermal efficiency increased to the boiler. In heating, hot water supply is widely used in condensing boilers, greatly reducing the fuel consumption. And other advanced technologies. boiler.

Hot water boiler in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas low emission fired hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).

6 tons gas steam boiler steam pressure adjusting a boiler operation, must frequently monitor the pressure gauge indicated. To maintain stable steam pressure, boiler pressure must not exceed the design pressure. Second, increasing boiler load: Steam pressure decreased boiler load is increased, if the level is high at this time, the amount of water should be reduced to a water supply or suspend, the amount of coal and increase the air volume. Gradually increase the amount of water at the same time to strengthen the burning, keep the steam pressure and the water level is normal. Third, the boiler load reduction: the vapor pressure rises to reduce boiler load, if the level is high at this time, the amount of coal should be reduced and the air volume, reduced combustion. Then the appropriate water reduction or suspension of water supply to the water vapor pressure and stability in the nominal range. Then press the normal combustion and the amount of feed water 8 to adjust. If the actual water level within the boiler is low, to increase the amount of water should, until the water level returns to normal after the combustion and needs to be adjusted according to the water vapor pressure and load changes.

Oil-fired boiler and gas boiler as the difference between the early stages of construction to complete our economy, our people's spiritual and cultural efforts to increase investment, with the attendant is demanding on the environment, air pollution is coal-fired boilers of large, first in the state it's now a rigorous, but the attendant is it a substitute for oil-fired boiler and gas boiler, that they have any difference? They belong to energy saving equipment, the combustion products of carbon dioxide and water, will not pollute the environment. The biggest difference is that they use different fuels, gas boilers use natural gas, city gas as the fuel, light oil, heavy oil which is used as fuel. In contrast gas boilers, boiler fuel cost is much higher than gas boilers, therefore, it is common for companies do not have a gas boiler operating conditions or institutions to use. Oil-fired boiler and gas boiler difference between: 1, different fuel: the former light oil, heavy oil as a fuel, which uses natural gas, city gas, liquefied petroleum gas as fuel. 2, the burner different: the former use of oil burners, gas burners later use. 3, different cost: the former high cost, about 1-2 times the cost of the latter. The same point fuel boilers and gas boiler: 1, the same boiler: the same tonnage same steam boiler or low emission fired hot water boiler of the boiler body. 2, the same auxiliary components: in addition to the burner, auxiliary oil-fired boiler and gas boiler accessories equivalent tonnage same. 3, the same production process: The process of production and processing were carried out in accordance with the same process and production standards. These are the difference between the oil-fired boiler and gas boiler, want to help you choose.
