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 hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).

What are the technical parameters of the gas boiler boiler parameters are: 1, boiler capacity, which is the output Q, units of 9th fired steam boiler in bangladeshs are tons / hour representation. Hot water boiler for heat MW / h represents; 2, pressure P, the unit is Mpa; 3, steam (or superheated steam) Temperature q, in degrees Centigrade. Hot water boiler expressed in terms of outlet temperature and return water temperature. Another area of ​​the heating surface of each grate area, fuel type, fuel consumption, water temperature, total drag, with the wind (the wind drums) the amount of exhaust gas temperature and the like. The expression model are: the number of drum (e.g., single drum D, S, double drum); drum arrangement (transverse type H, the Z vertical type); combustion (chain L, G stationary grate etc.); a fuel type (coal a, gas Q, Y fuel, etc.); a steam boiler is usually "tons / h" or "t / h" is the capacity of the boiler. With "Mpa" or "MPa" (old unit of "kgf / cm 2" or "kgf / cm2") of the rated pressure of the boiler, it represents the temperature at the rated pressure saturated steam and superheated by "deg.] C" (Celsius) steam temperature. Thermal Efficiency Heat Transfer Fluid is a boiler furnace or a thermal transfer process, heat is absorbed by water, steam or thermal oil, accounting for complete combustion of the fuel into the boiler heat released percentage capacity of 1t / h steam boiler, i.e. It indicates that the boiler may be over 1 hour into water of 1 ton capacity of saturated steam under pressure; 0.7MW of such water heaters and furnaces heat Transfer Fluid representations may generate heat corresponding to 0.7MW power over 1 hour ( equivalent to one ton of steam heat). Two water boiler is the heating means for the hot water boiler working fluid. Usually "MW" (MW), with the old unit "when Wan kW /" or "million kcal / h", namely "104kcal / h" is the capacity of the boiler, with "Mpa" represents the rated pressure of the boiler, with "℃" the hot water temperature.

What types of boiler pressure 9th fired steam boiler in bangladesh pressure steam boilers are common varieties of life, the pressure steam boiler also has another name called non-pressure steam boiler. High-pressure steam boiler is durable boiler is not under pressure, so there is no security risk, can be used for heating and steam supply. Working pressure of steam boilers requires energy from different fuels, different fuel types depending on and separate. 1, the electric steam boiler is an electric steam boiler to maintain normal pressure, electricity, steam boiler heating power as energy. Meanwhile, a computer equipped with a dedicated controller. Using a temperature sensor may be adjustable form a circulation system. By continuous acquisition of temperature, accurate control and regulation of temperature, to achieve the purpose of energy conservation and the automatic thermostat. 2, gas steam boiler with the implementation of the national natural gas project, gas boiler gradually been accepted. Gas steam boiler in a steam pressure of gas-powered boilers, gas steam boiler also requires computer controller. However, the difference is that electric steam boiler, gas steam boilers require the use of imported burner to heat water. 3, the fuel steam boiler can read the name of this steam boiler fuel steam boiler fuel in the fuel, including diesel, oil and kerosene. Fuel steam boiler burner needs to be, but the difference between the fuel gas steam boiler steam boiler and burner which is to be used.

How to maintain 9th fired steam boiler in bangladesh 1, when maintaining boiler, must cut off the power supply, must release pressure. 2, burners should be removed from boiler body every two months, and other foreign bodies such as carbon deposit and dust should be removed seriously. The photo-electric tube is polished once a month. The fuel filter should always be cleaned and filtered. Carefully clean the inner filter screen of the oil pump and do not destroy the gasket. The burner shall not run without oil to prevent damage to the oil pump. 3, the water level gauge shall be kept clean at all times and rinsed once a day by opening the cleaning valve to ensure the water level is clear. 4. The safety valve shall be pulled once a day in case of rust failure. 5, When the steam boiler stops running for a long time The power supply should be cut off and the maintenance work should be done: (1) dry maintenance, discharging the furnace water after the furnace is stopped, rinsing away the dirt in the furnace, drying the pot with a small burner fire (the burning time should not be too long, so as not to damage the boiler), Then, after all the boiler gas has been discharged, all pipe valves will be closed and checked every three months. (2), wet maintenance shall be applied to boilers with a period not exceeding one month, and the boiler water will be discharged after the shutdown, and the clean and full water will be discharged. Cut off the power supply and close the valve.
