Many food plants, hospitals, 10 tons of chemical used in small steam thermaxboilers s.m60 water shortages, how to make correct and rapid emergency treatment is very important as it relates to operational efficiency and service life of the boiler.
2. Which country will the boiler be used in?
On January regular press conference, Secretary, Ministry of Environment environment atmosphere Liu Bingjiang said: Through the joint efforts of the whole society, national ambient air quality is generally improving. But issues of current emissions of air pollutants is still high, industry structure, energy structure is still prominent, air pollution control remains to be done.
2019 is to win the battle of the blue sky in tackling it. China Environmental Science Research Institute Professor Xue Zhigang said China is still partial to change the energy mix of coal to Beijing and Tianjin, for example, though not local, but coal consumption per unit area of 5 to 6 times the national, so to adhere to focus total coal consumption areas under control.
First, the structure of coal-based energy, coal pollution characteristics significantly. Shaanxi, Shanxi coal-producing province is also the province's coal consumption, coal consumption Fenwei plain more focused, coal accounted for nearly 90% of energy consumption, much higher than the national average of 60%.
Second, the emphasis on regional industrial structure, industrial pollution emissions from large. Fenwei plain alumina, coke, iron and steel, coal, chemical and other heavy chemical industry, small-scale enterprises, low level of equipment, and most enterprises have yet to achieve a stable discharge standards, ultra-low emission completion percentage less than the transformation of thermal power enterprises in Beijing, Tianjin the level of pollution control needs to be improved.
Third, the prominent road transport pollution, emissions from large heavy vehicles. Fenwei plain is an important channel Shaanxi, Inner Mongolia and Shanxi coal Sinotrans, common to road transport, heavy industry-oriented industrial structure to further increase the pressure of road transport.
Hebei Province in 2019 government work report, determined to win the battle of the blue sky, ultra-low emissions to accelerate the transformation of key industries and promote clean coal casual alternative, "scattered dirt" dynamic business continuity cleared, Hebei Province, the year will be 10 million tons of coal Yajian thermal power 500,000 kilowatts.
Tianjin in 2019 to promote low-nitrogen transformation and construction work clean diesel transformation of mechanical gas-fired boilers, in an orderly urban and rural residents clean alternative to coal for heating, PM2.5年均浓度持续下降. In addition, Guizhou, Gansu, Heilongjiang and other places have made the coal control target.
It is reported that, after the heating season this year, the Ministry of Environment will work with ecological scientific and reasonable arrangements around 2019 bulk coal management plan. Regional authorities will further strengthen joint prevention and control, continue to implement the autumn and winter tackling action in key areas. In the future, China will focus on promoting the Beijing and Tianjin and the surrounding areas, as well as bulk coal governance Fenwei plains, to the 2020 heating season, the basic completion of the plains to live and bulk coal for heating in winter instead.
1, hypoxia combustion: gas pressure suddenly becomes larger, the absence of oxygen combustion prone, resulting in incomplete combustion of gas, carbon monoxide, smoke appears, there is loss of thermal efficiency gas boiler.
2, from the fire: if the gas pressure, the gas stream will cause the gas velocity greater than the burning rate, the flame away from the fire resulting from the flame hole edge called on to develop from the fire. This situation will result in flame or combustion instability, and even lead to security risks. General machinery comes with a high-pressure blast burner control, when the gas pressure exceeds a defined value the active flame protection.
3, the combustion peroxy: this occurs in the gas pressure is reduced, excess air appears, nitrogen and oxygen in the air reaction, resulting in excessive emission of nitrogen oxides.
4, tempering: If the gas pressure is very small, it will cause the gas flow velocity is less than the gas combustion speed, causing the flame tempering, influence the safe operation of the burner. General machinery blast burner comes with a low pressure control, when the gas pressure exceeds a defined value the active flame protection.
