With the rapid development of modern industry, emissions continue to air materialamount increasing, more complicated, air composition changes. In recent years, the stateactively to promote the "energy-saving emission reduction" policy, the country to startmonitoring "air quality index PM2.5" data to control the air pollution degree. Therefore, theuse of natural gas in industrial enterprises in the clean energy, has a major impact onenvironmental protection. At present, the fuel boiler fuel for diesel, heavy oil, this kind of fuelnitrogen oxides, the post combustion emissions of sulfur dioxide and waste gas and otherpollutants were much higher than that of natural gas, so the fuel boiler, to switch to naturalgas to the environment improvement plays vital role.From the economic considerations, oil prices continued to rise and the natural gas pricestability produced sharp contrast. The rapid development in most parts of the country, city gaspipeline construction is like a raging fire now, boiler in industrial enterprises can easily usenatural gas through the city underground gas pipeline, and diesel fuel is needed by the vehicletransportation, delivery to the boiler front, which also produced a no small cost to the boilerusers. Through calculation, to produce the same amount of heat under the effect of the use ofnatural gas, the boiler is lower than the cost of diesel fuel. For boiler users to use more fuel,boiler oil to gas transformation cost is expensive, but can be recovered in a certain period oftime, then will and fuel, save a large amount of fuel cost.The boiler fuel switching to natural gas in the environment, economic impacts areanalyzed in detail, the city of Shenzhen as the research object, the administrative area as theunit, carries on the contrast to the region all oil fired boilers to burn gas emissions emissionsbefore and after, the image reflected gas fired after the environmental aspects advantage. Theboiler is divided into different specifications, different specifications of oil fired boilers toburn gas, analysis of pollutant emissions and the user cost of fuel. The results show oil firedboilers to burn gas, both in the environment or the user economic benefits, have greatcontribution.
