natural gas driven boiler
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.
The CFB driven boilers will replace typical pulverized coal (PC) units that are outdated and worn out. Combustion of high-ash anthracite in the CFB boilers is inefficient, requires considerable co-firing of natural gas and produces high SOx and NOx emissions. The important boiler design and performance parameters, such as furnace height, fuel and limestone sizing, solids recirculation rate, combustion efficiency and emissions performance, were developed using the results of high-ash anthracite pilot CFB testing.
2, various post-combustion treatments
Many of the coal ash will happen after combustion in the boiler, in order to safeguard the health needs of the environment will be transported to the ash professional processing slag field, however, the use of gas-fired boiler is gas, there will be no remaining after combustion ash, so do not need to process it, not only to avoid the formation of environmental pollution also decreased the labor intensity and the amount of urban ash storage and transportation companies.
Overview of 20 Ton Gas Fired Steam Boiler
20 ton gas fired steam boiler for sale in ZG Boiler is a type of boiler which takes natural gas, light oil, heavy oil, biogas, city gas and others as its fuels. ZG Boiler supplies both single drum and double drums gas fired steam boiler for its customers. The following is the single drum gas fired steam boiler and it is WNS series boiler in ZG Boiler.
20 ton gas fired steam boiler in ZG Boiler has adopted three pass return structure, which can improve the combustion efficiency of the fuels. It adopts advanced corrugated furnace structure, and it can increase the heat transfer area and ensure the tightness of the furnace.
