use of coal boilers in paper industry
With the development of the economy, people begin to seek for a new type lifestyle and they have higher requirement to the living environment. Green economy and sustainable development have become the belief of modern people. In Beijing, more and more use of coal boilers in paper industry rooms will be turned, and the energy shift to coal burning to clean energy ---natural gas. It is understood that this year Beijing will build a number of gas pipeline in 47 projects, 52 boiler rooms “from coal to gas”, to provide gas source. After this 52 boiler rooms renovation completed, it can be reduced to about 316,000 tons per year of coal-fired to reduce sulfur dioxide emissions of about 3,839 tons, about 1,287 tons of nitrogen oxide emissions. In recent years, Beijing continues to increase efforts to adjust energy structure, promoting clean energy from coal to work. ZG Boiler is one of the natural gas fired boiler manufacturers, and it is committed to design and manufactured industrial boiler heart and soul.
As one of Beijing's air pollution emission standards of the most demanding urban, environmental control is very strict. Beijing primary school campus Emerald City as one of the cradles of socialist culture successor, in terms of the quality of students' learning environment is put emphasis on one hundred percent. October 2017, Beijing primary school campus Emerald City with my company, signed a two Thalia T6 series vacuum hot water use of coal boilers in paper industry for winter heating use.
1. Oil and gas use of coal boilers in paper industry
2. Coal boiler
The need for paper industry paper industry conversion of coal-fired use of coal boilers in paper industrys to gas boiler is a boiler equipment industry needs is more important, because a lot of links to the papermaking process requires a lot of steam drying, stereotypes and so on. However, along with the national policy of environmental protection departments to ban coal-fired boilers, and now more and more manufacturers have to use coal-fired boilers to coal-fired boilers upgrading or purchasing a new low - NOx emissions. Paper mill boilers from coal to gas fired boiler is an important direction of current reform, is one more type of enterprise transformation, especially in the area more natural gas, coal into gas boiler is the main way. 1, in order to transform mechanization layered fired boiler gas boiler, you should first remove the front arch and a rear arch, while increasing the bottom heating surface, instead grate, grate to prevent overheating, combustion; 2, through the furnace heat transfer calculation methods determining the size of the boiler, furnace flame center position, and then pouring furnace work. In order to avoid the center position after arch boiler tubes, based on the original slope of the original arch made pipe. 3, the furnace in order to prevent an explosion, when the coal-fired boiler furnace gas is substituted, or when fuel not atomized combustion gases in the furnace incomplete combustion or heating surface of the end of the furnace, a fire or explosion occurs, should be mounting the appropriate parts of the boiler explosion vent, and to increase the ignition and flame failure protection program control to automatic control means, to ensure safe operation of the boiler. 4, is closely related to the selection and arrangement of the burner and furnace, the filling degree of the flame in the furnace should preferably not to form a dead air. Gas burner arrangement considered reasonable and piping layout, easy operation, maintenance and inspection.
