March 19, 2019, Tangshan, Hebei Province, the city government official held "2019 Tangshan depth control key industries scientific and technological achievements Matchmaking" meeting the cement industry on air pollution emissions caps mobilization discussion. According to the news conference, Tangshan City Cement companies need before the end of September this year will be dust, sulfur dioxide, nitrogen oxides are controlled to not more than 10mg / m³, 30mg / m³, 50mg / m³. Official documents will be introduced in the near future.

It is reported, as early as in September last year, Tangshan cement industry in particular has a value of air pollutants emissions of nitrogen oxides emission concentration is less than 50mg / m³ proposed.

September 3, 2018, Tangshan Municipal Government issued the "ecological environment in Tangshan depth remediation tackling month action plan", "plan" industrial enterprises in pollution control, discharge of pollutants in the cement industry to make the following requirements: single production of raw grinding material, bag filter employed; one mill kiln production process, humidification tower may be used - electric precipitator dust collection system, dust emission concentration ≤10mg / m³. Rotary kilns for cement kiln and, preferably high dust coating, conditioning tower may be used - electric precipitator, dust emission concentration ≤10mg / m3, the concentration of sulfur dioxide emissions ≤50mg / m3, nitrogen oxides emission concentration ≤ 50mg / m3.

Gas fired boiler manufacturing companies industrial laoss into boilers which benefit: the traditional coal-fired steam boiler in the use of the process releases large amounts of carbon dioxide, sulfur dioxide and other harmful gases, causing serious air pollution and acid rain, and coal are non-renewable resources, Earth the storage capacity is limited, and the price of coal is relatively high with the successive implementation of the national policy of reform coal, coal-fired boiler traditional high pollution and high consumption market gradually been criticized, many provinces and cities have started from coal to gas work, namely the traditional coal-fired boilers to become clean non-polluting gas boilers, and strive to achieve the unity of economic and social benefits. In conventional coal-fired boilers used in the process releases large amounts of carbon dioxide, sulfur dioxide and other harmful gases, causing serious air pollution, and acid rain, while the coal are non-renewable resources, the limited storage capacity on the earth, and the price of coal is relatively higher, therefore, imperative coal to gas has the advantage.

Increase productivity boiler manufacturing companies industrial laos system must first be optimized for verification, including the entire steam system for a complete analysis, and focus on some of the energy waste places. Via check can often find opportunities to save energy, increase productivity, and environmental protection have a positive contribution of. Check includes a steam generation, distribution, use and condensate recovery. The main steam waste requiring special attention place: exhaust gas boiler: boiler efficiency emissions system the most important indicators, the loss of energy is the most important place. Combustion air: general air enters the combustion furnace of the genus room temperature, require a lot of heating energy, i.e., the most commonly used power saving mode using a high temperature exhaust gas to preheat the combustion air of boiler, boiler efficiency can be significantly improved. The fuel / air ratio: Proper oil / gas mixture can only complete combustion, if the lack of air, combustion is incomplete, not only smoky pollution, environmental protests caused nearby residents, and easy carbonized grease gun and boiler heating tubes affect performance. If excess air is formed wasted energy, reducing boiler efficiency. Via the oxygen content of the tail gas can appropriately adjust the oil / gas ratio. Oil-fired boiler exhaust gas which content 3%, i.e., the excess air of about 15%, as the standard combustion control.

Gas oil-fired boiler manufacturing companies industrial laos room ventilation system designed along with economic development, energy supply and demand changes in the relationship between environmental protection requirements increase, electricity and oil and natural gas in recent years, increasingly used gas oil-fired boiler. The gas oil-fired boiler room design related to people's life and property security of the country, but also can ensure the normal operation of critical boiler. In addition to the location of the boiler room and capacity to meet the relevant specifications, the design of the ventilation system which is also an important element in the design of the boiler room. However, due to the content of conventional ventilation and manual specification relates to small, there is no specific calculation method is given, designed to bring some difficulties. In this paper, problems in this area, combined with engineering experience of the author, make some analysis, calculation and discussion, put forward their views, for your reference. 1.
