economic and efficient 1100 kg steam boiler
4, explosion caused by severe overpressure;
5, due to the failure of safety accessories, structural design is not fair, material decay and other reasons, resulting in boiler explosion.
Around the city to promote the coal to gas project, the major institutions of the heating system put forward higher requirements. Central Conservatory of Music is available to students and teachers clean, safe, comfortable, energy-efficient heating environment, protect the health of teachers and students, to transform the traditional boiler treatment. Praise fast boiler Willie sharp series obtained in the transformation of low nitrogen boiler major institutions in Beijing, the Central Conservatory of Music in late 2017 with the signing of fast boiler boiler purchase contract, ordered six Willy sharp series V6-99, to for the entire school's heating facilities.
In fact, from the point of view of energy conservation laws, the thermal efficiency does not exceed 100%. However, there are two values in the professional sector in the gas burner - high heat value and a low calorific value. Of other European countries, like in the definition of thermal efficiency, without the high heat value of the fuel is regarded as a boiler heat input, the heat thus produced after condensation of water vapor in the flue gas has not been counted in the thermal efficiency.
Coal boiler developed primarily as fuel for power generation, fuel gas-fired industrial boilers major proportion of the total capacity of gas-fired boiler fuel in industrial boilers are generally occupied by more than 90%, for example, US 98%, Japan 99%. The late 1950s, China's Harbin, Wuhan and other places of the former Soviet Union boiler plant started using technology to produce fuel gas-fired boiler. By the early 21st century, the national fuel gas-fired boiler has accounted for about 6% and 10% of the total capacity of industrial boilers with the total number of units, annual production capacity of industrial boilers according to calculations, the fuel gas-fired boiler about 15%.
