In early 2019, Hebei Province Department of Finance summarized the draft 2018 budget and financial performance in 2019 budget, which states that: 2019 in terms of air pollution control to invest 8.23 ​​billion yuan, the focus for rural clean heating, open pit mine remediation, new energy vehicle application, shutting down out of thermal power and other aspects. Specific details are as follows.

First, support for air pollution control

Continue to increase investment, air pollution control for the central funds 6.372 billion yuan, accounting for 31.9% of the total size of the national capital, the total ranks first in the country; the provincial capital issued 8.93 billion yuan, an increase of 6.78 billion yuan over the previous year, investment as the largest ever. Strong support "double generation" implementation of the project, the timely disbursement of rural "double generation" subsidies 6.627 billion yuan to protect people's warm winter; newly acquired Handan, Xingtai, Cangzhou, Zhangjiakou City 4 become a pilot clean warm winter, the province currently 8 atmosphere contamination of the transmission channel and the city of Zhangjiakou city have all been incorporated into the national pilot for three years will receive a total of 14.1 billion yuan of central funds.

Therefore, to ensure a reasonable selection of boilers, paper and industrial users in the selection of the gas boiler, to note: 1, the fuel of choice to meet the environmental requirements; 2, flue gas emissions to meet local environmental policies; 3, choose energy-saving effect of a good boiler to ensure profitability;

At the same time, achieve sustainable development is also the focus of green chemical industry needs a breakthrough. Although the chemical industry is an important part of the national economy, however, mention it, our first thought is of high pollution, high toxicity. Therefore, how to reduce pollution and achieve sustainable development has become a top priority of all issues. Boiler chemical industry as an indispensable production equipment, damage to the environment if it is reduced, it is to achieve sustainable development has added new impetus. Gas boiler appears just to meet this demand, the development of chemical industry opened a new prologue.

Hazard Ultra-low-load operation of the boiler What? Coal-fired boilers is 70% to 100% of rated load, fuel gas boiler 60% to 100% of rated load. Ultra-low-load operation is deemed to run below this range. Then the ultra-low-load operation of the boiler harm What? Fuel gas-fired boiler factory and you came to talk about it! 1. difficult to guarantee the quality of steam: with the boiler load decreases, the steam temperature and humidity will be affected, in particular for a boiler with a superheater, boiler load is reduced, resulting in reduced exit steam temperature is difficult to maintain rated steam temperature, steam quality deterioration. When the superheated steam temperature drops below nominal, soda heating surface system conditions will enter the danger zone, when the load is low zui called technically permissible load. 2. boiler water circulation decreased reliability: fuel gas circulation usually natural circulation. Ultra-low-load operation, because a small amount of fuel into the boiler, the temperature drop across the furnace, the heated water wall weakening, boiler water circulation flow rate will be reduced, reliability is lowered circulation. 3. The rear of the boiler heating surface acid corrosion aggravated: Ultra load operation, the furnace temperature was decreased to varying degrees departments, the exhaust gas temperature will be reduced. It is easy to make the heating surface of the metal wall of cryogenic temperature below the temperature of the vapor *** sulfuric acid, sulfuric acid vapor condensation heating surface will be at a low temperature, resulting in low corrosion of heating surfaces. In summary, fuel gas-fired boiler ultra-low-load operation this issue, we can not be ignored.
