After removal of coal-fired boilers, textile industrial park will access a unified steam heating system, the coal-fired boiler plant will be dismantled access system, both low nitrogen environmentally friendly and energy efficient.

In recent years, Hutubi County to respond positively to China's environmental protection policy, and vigorously promote the "Blue Sky Project", to conduct a comprehensive environmental management and air pollution control activities that will improve air quality as the top priority of economic and social development.

It is understood that Hutubi County this year to increase environmental protection efforts, the New Chemical Materials Park, Textile Park, a new industrial park and other parks coal-fired boilers are dismantled processing equipment, present the industrial park has been demolished 67 companies a total of 98 fuel stations coal boiler, after the removal of 10,000 tons per year to reduce coal pollution.

First, the most commonly used two tons pressure hot water boiler is the boiler pressure, the common model WNS1.4-1.0 / 90/70-Q type, meaning that the model is expressed by a horizontal type internal combustion chamber pressure boiler and then , rated evaporation amount of 2 tons per hour, for use in a hot water boiler rated thermal power is visible, so the rated heating power to indicate that the thermal rating of the hot water boiler of 1.4MW, behind 1.0 / 95/70 meaning expression are rated water pressure is 1.0MPa, the water temperature was 95 deg.] C, the return water temperature is 70 ℃, as well as the meaning of the final letter Q is expressed as the design of the fuel: natural gas, town gas based fuel gas . Second, because the two tons pressure hot water boiler pressure boiler belongs to a very small boilers, so not everyone illustrate, here to introduce the characteristics under normal pressure boilers, pressure boilers boiler no respect particularly high demands, but requires its auxiliary must be very high profile, because the pressure of the boiler pressure is stable guards from beginning to end has always been a kind of pressure, thus requiring special fireman on duty, and need a year registration tests, procedures are complex so the current range of applications in the market is very limited.

The project will build 220t/h circulating fluidized bed steam boiler dongfeng boiler. Instead of coal-fired heat supply, the waste coal stone are utilized to achieve energy saving effect. In the meanwhile, by using circulating fluidized bed(cfbc) boiler, the emission of NO and SO2 will be efficiently reduced.

I. Definitions rated steam pressure of the boiler: rated steam pressure refers to steam at a steam temperature of the boiler thermal efficiency predetermined steam boiler dongfeng boiler, steam temperature, water temperature, and a nominal long-term continuous operation must ensure boiler superheater main valve at the outlet boiler pressure, which is indicated on the nameplate boiler pressure. For boiler without superheater, denoted by the saturation vapor pressure at the outlet of the main valve.
