explanation regarding boiler in steam power plant

Operation of the gas explanation regarding boiler in steam power plant furnace interior wall Why would subjected to vibration of the dynamic pressure boiler furnace gas flow field, the atmospheric pressure outside of the subject; when the furnace pressure fluctuations in the gas flow, the furnace wall will be excited vibration, the actual production by pressure fluctuations in the gas boiler big impact, resulting in unstable combustion furnace pressure fluctuations, frequent changes in pressure inside and outside, leading to the boiler furnace wall vibration. Vibration analysis gas boiler reasons: 1, alternately hot and cold source is a heat boiler, there is a source of heat and cold alternating process between modern boilers and burners. This process is likely to vibrate, hot flue gas temperature in the furnace up to 800 deg.] C in general to 1000 ℃, combustion-supporting gas at a high temperature gas turbine exhaust gas temperature should be at 500 ℃, while the temperature of the air combustion boiler using only the current 25 ℃ to 50 ℃, which has the potential to generate sufficient vibration excitation. This is especially prone to small and medium sized boiler Boiler vibration. 2, the lower portion of the boiler furnace pressure inside and outside the combustion zone, an upper portion communicating with the flue, the runtime filled with a constant flow of the combustion gases in the furnace, the entire furnace space forms a gas flow field. The inner wall of the furnace by effect of the dynamic pressure of the furnace gas flow field, the atmospheric pressure outside of the subject; the air flow when the furnace pressure fluctuations, vibrations will be excited furnace wall, a large gas pressure fluctuations affect the boiler actual production by , resulting in unstable combustion furnace pressure fluctuations, pressure inside and outside the frequent changes, resulting in vibration of the boiler furnace wall. 3, furnace wall furnace wall less rigid vibration caused by unavoidable reasons combustion dynamics, which requires a certain degree of rigidity of the furnace wall. Paper Format. Rigid beam function is to protect the furnace and flue in the furnace operating pressure or deflagration conditions from destruction, namely to increase the rigidity of the furnace wall by adding rigid beam. Inadequate or installation not meet the design requirements will occur more serious vibration rigid beam furnace wall rigidity. 4, excessive wind wind caused the ignition delay caused by deflagration. In addition to the above four points, the high-load boiler ignition, smoke tube fouling can also cause problems such as vibration boiler operation.

Second, the overall design and use of explanation regarding boiler in steam power plants

Even the same material condenser and energy conservation, and use of different design or will affect the life of the boiler. For example, whether to a condenser water systems and water separate, protective measures when the boiler outage, anti-frost water protection measures heating season.

Gas-fired steam explanation regarding boiler in steam power plant can be installed in the basement they often ask users can not install the boiler in the basement or roof level. This issue involves more thing, if it is pressure hot water boiler, quality control section and the fire department might agree with your installation, if steam boiler, with the kind of pressure I'm afraid a bit difficult. The boiler pressure and divided into two pressurized gas steam boiler pressure hot water boiler heating system refers to a boiler without pressure, usually does not install any pipe valve is always open to the atmosphere is generally not explode, the safety performance it is good. Pressure boiler does not belong to special equipment, does not require special approval, and boiler with pressure you need to go through a series of examination and approval procedures.

Burns Hospital Affiliated Hospital of Shanxi Linfen Linfen Steel is attending a hospital burns burns and other diseases. Hot water explanation regarding boiler in steam power plant is essential hospital equipment heat, hot water output can provide disinfection of medical instruments and ward heating demand. With constantly improving our environmental policy, boiler correspondingly introduced more sophisticated Use. Linfen hospital burns to respond positively to the national environmental policy, decided to introduce an environmentally friendly low nitrogen gas hot water boiler. Taking into account the special circumstances of the hospital, the boiler should also have the use of safe, clean overall characteristics. Based on the above considerations, finalize the Linfen hospital with burns boiler party cooperation fast, fast is provided by one side of a gas condensing pressure hot water boiler (CWNS2.1-95 / 70-Y.Q).
