boiler and their types for thermal power plant

Precautions gas boiler and their types for thermal power plant installation: after the user purchases a gas-fired boiler, also face the problem of transportation and installation, how to ensure proper installation of the boiler from the boiler so that in normal use, is the focus of attention of many users. Fast boiler boiler with years of experience in the installation, the following precautions everyone summary, we hope to help more users understand the correct methods of operation when installing a gas boiler.

Currently, Yancheng City, Jiangsu Province, has issued the latest "Battle of Yancheng win the blue sky plan", in full swing atmospheric environmental governance. Details are as follows.

First, to promote non-power industry emissions of nitrogen oxides depth and steel industry to implement ultra-low emissions transformation. Achieve before the end of June 2020 discharge standards garbage incineration industry, gas-fired units are encouraged to implement advanced nitrogen removal, implementation of coal-fired units plume of white vapor recovery off the project.

Second, the implementation of total coal consumption control. Accelerate the "Yancheng reduce total coal consumption special action plan", strictly implement the same amount of coal consumption reduction alternative requirements, increase bulk coal remediation efforts for non-electric Yajian coal industry, and gradually increase the proportion of coal. New coal coal project implementation reduction instead. According to focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, the power sector coal consumption accounts for the proportion of total coal consumption to increase more than 65%. Continue to promote alternative energy coal and oil, electricity consumption by 2020 (calculated as the supply of standard coal) accounted for about 55% of the total social energy consumption.

The development of special programs, shutting down vigorously eliminate environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units. Strict control of new coal-fired units installed capacity, the new electricity in the area rely mainly on non-fossil energy generation and transmission to meet outside.

Third, carry out comprehensive improvement of coal-fired boilers. Before the end of 2019, 35 tons of steam / hr and coal-fired boilers or eliminated all clean energy alternative embodiment, suitable remediation in accordance with the principle of the electric power, gas and other appropriate gas is to encourage the use of solar energy, and biomass energy; promote clean coal use, promoting clean and efficient coal-fired boiler, steam 65 t / h coal-fired boilers and more energy-efficient and ultra-low emissions completed transformation; low-nitrogen gas boiler is substantially complete transformation; urban area biomass boilers embodiment ultra low emission transformation; rest boilers with all the special emission limit requirements.

Configuring steam boiler and their types for thermal power plant feedwater and steam boiler feed water equipment device points in claim 4 points: water supply system (1) of the steam boiler, should ensure safe and reliable water supply. (2) steam boiler should spare water supply equipment. Arrangement and number of units and capacity of backup water supply system of water supply equipment, should meet the following request: ① boiler steam boiler should be at most two vertical work to pump ** (one spare). ② Two capacity to pump, not less than 120% of the nominal overall operation of the boiler and the amounts of evaporation. ③ When the boiler room above three feed pump apparatus, which feed water total capacity should be: when the maximum capacity of a feed pump deactivation, the remaining capacity can always run parallel to the pump is not less than the rated boiler all running evaporated 120% of the sum of the amounts. (3) to the pump head (i.e., height of the water column required to overcome the static pressure of the respective dynamic pressure) should be greater than or equal to the algebraic sum of the following: ① water pressure drop difference water supply system (water column hydrostatic) and the water supply system. ② hot water boiler safety valve at the design pressure set pressure. ③ economizer system pressure drop drum. ④ The above three multiplied by the algebraic sum of the amount of 1.05-1.1 rich as appropriate.

Boiler hot water boiler and their types for thermal power plant-depth study of aspects of the in-depth study of hot water boiler feed water parameters and other aspects of the hot water boiler feed water and parameters like, for this kind of boiler, the following will explain and answer some questions in order to advance their learning process. In addition, you can also learn the content, so that they have some gains and progress, in turn, shorten the learning gap between target. Hot water boiler replenishment rate of overweight, should be how to deal with? It's a small amount to pay, whether it is normal? Hot water boiler, if it exceeded the rate of pay, then we must identify the reasons are, first cut off all the water put to check whether there is run, run, drip and drain phenomenon, any, should be eliminated so that the pay rate back to normal. Boiler parameters, if it is for the hot water boiler, then, specifically what? Steam boiler difference? Boiler parameters, which if it is for the hot water boiler, then specifically, for the thermal power, water pressure and supply and return water temperature three. For steam boiler, the amount of steam that is, the operating pressure and the steam temperature three. So, these two boilers in the boiler parameters, is not the same, can not be equated. Rated temperature hot water boiler, which specifically refer to? Notes on the boiler, which prevent matters? Rated temperature hot water boilers, the specific terms, it means that this kind of hot water temperature at the outlet of the boiler . As for some considerations on the boiler, on the matter of preventing them, there are several less, it is as follows: to prevent boiler scaling, prevent furring, to prevent fouling and to prevent water hammer. In the boiler, a small amount of replenishment is inevitable, however, to note that, should strictly control the quality of supply water, deoxygenated water is recommended, because it can avoid fouling, or scale issues such as boilers. And this is for the normal operation of the boiler, is also useful.
