350 hp trailer mounted natural gas steam boiler
Natural gas boiler once a day to check how long it takes much time to check the gas boiler natural gas boiler includes a gas water boiler, gas hot water boiler, gas 350 hp trailer mounted steam boilers, gas hot water boiler which is also known as gas heating boilers and gas boilers bath , gas boilers name suggests refers to the fuel gas boilers, gas boilers and oil-fired boiler, electric boiler compared to the most economical, most people have opted for a gas boiler as steam, heating, boiler equipment for bathing. According to market surveys, gas boilers and coal-fired boilers scheduled inspection time, like once a year, April 19, 2018, the special prosecutor in Daxing District in Beijing Yizhuang three sheep, six 68MW heating Limited (approximately equal to 40T) of gas heating boiler regular inspections. On-site inspectors checked the calendar year of inspection reports, operating records, factory data boiler, the operator asked in detail about the boiler operating conditions during the winter heating, internal inspection carried out in accordance with these four boiler inspection program. Focus on examination of water tube boilers, membrane wall inside the furnace tubes, burners, fire insulation materials, while making inspection records.
Boiler steam temperature affect the safety and economy temperatures above will be lower than the rated temperature of the device, it will have a bad effect. If the temperature exceeds its rated value, the boiler will cause overheating of the relevant metal material, material creep acceleration, will shorten the life of the boiler. If the temperature is too high, but some of the key components of the boiler would cause damage, can also cause serious and even superheater tube rupture. If the temperature is lower than the rated temperature, vapor enthalpy is reduced, increased air consumption, decreased economy. This will reduce the thermodynamic cycle efficiency of the plant, the steam humidity at the last stage blades of the gas turbine increases, causing erosion and damage to water droplets gas turbine blades, affect the safe operation of the gas turbine. Ruoyin with water vapor causes a decrease in temperature, the moisture in the salt impurities formed in the superheater scale, pipe valves, gas turbine blade, because the superheater lead to reduced heat transfer, the temperature decreased, damage increased wall temperature; and cause the valve plug, the operation failure; and a gas turbine blade erosion, loss of balance and vibration occurs. Temperature fluctuations reason superheater actual heat transfer the vapor does not reach the required amount of heat absorbed corresponding balancing. When the heat absorbed is greater than the heat transfer, the temperature rise; conversely decreased. Many factors affect the temperature change, including both gas side and the vapor side. Such as boiler load increased, but also to ensure the boiler load unchanged or decreased in order to prevent pressure shall increase the amount of fuel and air supply, strengthen the burning, causing the furnace exit flue gas temperature of the flue gas volume increases and lower water temperature , temperature increase; If the oil and gas fuel is combusted in the furnace carbon black is not fully formed, into the superheater flue causing secondary combustion, but also greatly increase the superheat temperature. Reducing the temperature of the main reasons: improper adjustment of combustion, low flame center furnace; superheater area is small, or too much leakage at the furnace wall; Save water flow rising or temperature reduction; drum water level or high gas-water separator separating efficiency is lowered, the humidity of the vapor is increased; superheater tube fouling, reduced heat absorption and the like.
Fangkuai Boiler is based on low-nitrogen energy-saving and environmental protection. It focuses on the development trend and uses universal excellent technology, products and services. According to such a method, it is now applicable to the development of society around the world, promotes cutting-edge work in the future manufacturing industry, and maintains the ideal use of customers in various industries.
4 tons of 350 hp trailer mounted steam boiler before firing what needs to be done to prepare a deal boiler conduct a comprehensive inspection before Sheung Shui, the water is softened before boiler water filling. 2, Sheung Shui should check whether there is water leakage valve, leaks should be immediately removed when found. 3, the check Sheung water temperature, pressure gauges, water level, no good production of inlet and outlet valves, smoke profile, said shutter is flexible, the flue gas channel is smooth duct, each cleaning doors are tight. 4, before firing coal with water 8-10%.
