working process of thermal power plant boiler

Of course condensing working process of thermal power plant boiler is higher than the average cost of gas boiler, then why should it develop condensing gas boiler? According to statistics, the average per square meter of ordinary gas boiler consume more than 10 cubic meters of natural gas, and the type of boiler consumes only 5-6 cubic meters per square meter of natural gas, can save operating costs by about half, in a large cell, capable of annually save a lot of money, so early investment costs will soon recover.

Hot water working process of thermal power plant boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, steam having a certain outside thermal energy output, the high-temperature water or an organic heat carrier. Used for thermal power plants, ships, locomotives and mining enterprises.

In the near future, at home and abroad more than hazardous chemicals, major accidents have occurred, causing casualties and property losses. Is a profound lesson, Henan Energy Regulatory Office will co-Provincial Development and Reform Commission issued the "Notice on alternative transformation of the province's coal-fired power business major hazard (liquid ammonia tank)" and actively promote the province's power industry ammonia tank alternative transformation.

"National Development and Reform Commission and the National Energy Board to implement the views on the promotion of electricity reform and development of the field of safety of" clearly "to strengthen the major hazards source control, there are significant hazards during the production of coal-fired power generation enterprises should study the implementation of major hazards alternative rehabilitation programs. " Henan Province TV as fire, liquid ammonia tank safety risk management and control situation is grim. To actively implement the "opinions" requirements, Henan Energy Regulatory Office investigation and carefully combing the province's power industry the basic situation of major hazards, and actively carry out reconstruction work research initiative to communicate the situation with the Office of the Provincial Development and Reform Commission, the provincial emergency management, efforts to promote reconstruction work as soon as possible. "Notice" requirement province of the power generation enterprises should further enhance political stance, overcome difficulties, vigorously promote the major hazard (liquid ammonia tank) and Improvement, under the premise to ensure safe production, the province's coal-fired generating units and strive to 2020 in liquid ammonia tank renovation completed before the end of December. New coal-fired power generation projects should all use the technical route no major hazard.

Next, Henan Energy Regulatory Office will replace liquid ammonia around the transformation as an important safety regulation. For failure to complete the transformation of liquid ammonia replacement power companies, to be included in the list of key regulatory target, for there are significant risks or accidents in accordance with regulations to be strictly punished according to law, and urge enterprises to strictly implement the main responsibility to effectively prevent accidents, efforts to increase intrinsic safety level of the enterprise.

Steam working process of thermal power plant boiler desuperheater role and pressurized combustion steam boiler in the boiler is favorable, I believe we are not unfamiliar, because it is not just the type commonly used in the boiler, and in front, but also knowledge in this area, so that we able to become familiar with and understand this kind of boiler. But for now, it has not reached the intended learning objectives. So, then, will continue to study and work steam boiler, I hope you can learn to some progress. 1. Why not suitable for steam boiler heating? This is because the pressure of the steam boiler is very high, and their requirements for piping and accessories, is relatively high. So, on this invisible, it will increase costs and expenses. In addition, the installation of a steam boiler is not very simple. Therefore, based on these factors before reaching this conclusion. 2. Steam boiler desuperheater, what their role is? Boiler steam desuperheater, which is generally in the steam supply pipe, its main role is to reduce the steam temperature, so as to achieve the desired requirements. Desuperheater, which in kind, type, and mainly the surface of both water-jet. For surface type, we must know that it is mounted in a cylindrical barrel U-shaped tube, or a recuperative heat exchanger. And that the water quality of the cooling water, is of no special requirements on the scope, mainly low-pressure steam boiler. 3. The negative pressure steam boiler combustion, boiler whether beneficial? If the negative pressure combustion steam boiler, then, which specifically refers to the boiler combustion chamber, i.e. the furnace, is less than one atmosphere. The means to achieve it, it is achieved by balancing the ventilation system. Pressurized combustion, which does not increase the combustion rate of the steam boiler, or to maintain combustion stability, but, if the conditions are bad, then sealing the furnace, combustion positive pressure, will increase insecurity, the work environment is unfavorable . Therefore, only the negative pressure combustion to avoid the above problems.
