Solution: In this case should be maintained to run at reduced load short time, until the tnb boiler manjung 5 power plant slow to a stop, and finally the withdrawal of the remaining water in the furnace, the furnace temperature and reducing the pressure, which is determined blast furnace and isolated from other steam main pipe.

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.

Third, high cost

Due to advanced technology, the price of ordinary steam boiler steam boiler low-nitrogen ratio of slightly more expensive, but if you then it's better energy-saving effect of fuel in the long run, long run down, save the money to buy than the original more price difference can be described as highly cost-effective products.

For different working pressures tnb boiler manjung 5 power plants, to have a separate steam pipes and water pipes, respectively. If when a combination of the main steam pipe, the steam pipe to be fitted with high pressure apparatus and the automatic depressurization safety device that prevents the low-pressure side of the overpressure. When the water pressure does not exceed 20% of the maximum pressure, the system can feed water to the boiler feed water from the total.
