is the burning rice husk on boiler hazardous

Since Prime Minister Li Keqiang in the "five" proposed "Blue Sky Wars," after the strategic plan states that China provinces and cities are doing to improve environmental protection. Jilin Provincial People's Government recently issued a "Jilin Province to implement the winning Blue Sky Battle three-year action plan to implement the program," coal-fired units will conduct a comprehensive reform.

Jilin Provincial People's Government recently issued a "Jilin Province to implement the winning Blue Sky Battle three-year action plan to implement the program" (hereinafter referred to as the "Program") said that before the end of 2018, the province's 300,000 kilowatts or more coal-fired units completed ultra-low emissions transformation. Continue to promote the 200,000 kilowatts class ultra low emission coal-fired unit renovation project, before the end of 2019, ultra-low emissions and strive to transform the province's total unit capacity of thermal power capacity of more than 75%.

"Program" also proposed to complete the transformation of ultra-low emission electricity generation units appropriate to increase the number of hours. Vigorously for shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. Coal-fired generating units to increase the technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate coal heating boiler pipe network coverage and the range of loose coal. In areas do not have the cogeneration district heating conditions, the existing multiple small coal-fired boilers, alternative construction of large-capacity coal-fired boilers in accordance with the principle of equal volume. Before the end of 2020, within a 15 km radius of 300,000 kilowatts of heating and cogeneration power plant above range, in the case of cogeneration heating load to meet the heating needs, in addition to the need to retain the peaking boiler, coal-fired heating boilers and small coal-fired thermoelectric behind all closed down integration.

In addition, long-term control of total coal consumption in accordance with planning requirements, Jilin Province, to continue to reduce the amount of coal consumption, coal consumption in new coal projects to implement alternative reduction, by 2020, reduce the proportion of coal accounting for the province's total primary energy consumption to 63% the following. According to focus on the use of coal and clean use of principles, focusing on reduction of non-power coal, increase the proportion of electricity from coal, the state-assigned task is completed, the province's electricity by 2020, the proportion of thermal coal coal consumption reached more than 55%.

In the future, the province will carry out a comprehensive environmental aspects of governance, economic development and environmental protection go hand in hand.

First, check whether the diameter in claim is the burning rice husk on boiler hazardous pressure hot water boiler is the same as the opening to the atmosphere, under any operating conditions, the water level in the boiler are zero gauge pressure boiler. Therefore, before use, the user should check for new boilers, in particular, check whether the diameter to meet the requirements. Further, the communication tube should be prohibited in any valve provided to ensure smooth takeover. Generally, professional supply of pressure hot water boiler will spray "pressure boilers may not use pressure and hot water outlet temperature should not exceed 90 ℃" warning labels in the apparent position of the furnace. Second, installed by professionals, debugging initial purchase use, pressure hot water boiler manufacturer will recommend the installation and commissioning of the boiler by professionals to be responsible. Once operational, non-professionals are not allowed to change the structure of the boiler, free installation system piping, valves. At the same time, it should also be noted that must not be converted boiler pressure hot water boiler pressure. Third, to ensure that sensitive and reliable boiler safety accessories

Henan steam preheater gas is the burning rice husk on boiler hazardous start-up and shutdown 1, Henan gas boiler steam preheater how to start? Only after starting the blower, a steam inlet to the steam air preheater is heated, the preheater normal start operation is as follows: (1) open twelve steam preheater preheating steam inlet bypass valve and piping heating pipe, while discharging the pre- noncondensable gas heater, until the vapor pressure reaches 0.1MPa ~ 0.2MPa side again when close the upper discharge valve. (2) hydrophobic close the intake door, turn on the water trap before closing, after opening the door manually hydrophobic, hydrophobic bypass valve closed. (3) after opening the steam inlet damper door manually, and then close the bypass valve into the steam, and then adjust the degree of opening of the steam inlet damper according to an amount of heating steam. 2, Henan gas steam boiler outage how preheater? (1) Close twelve steam into the steam air preheater damper, front manually operated door, stopping the steam into the preheater. (2) the upper open air preheater exhaust door, turn on the water trap door open, drained hydrophobic. (3) If the temperature and pressure reduction device is put into operation, but also to stop it. (4) the steam air preheater longer outage, should tightly close all valves on the air preheater.

Gas is the burning rice husk on boiler hazardous room building requirements: the boiler room building as an important bearing boiler operation, in the construction process to follow certain design specifications. The latest development of China's "boiler room design specifications" (GB50041-2008) for the gas in the boiler room building made specific requirements.
