bono energia boiler steam generator
To further reduce emissions, improve air quality, the Shanghai Municipal Government put forward the views of accelerating the implementation of small and medium sized boilers mentioned standard transformation of the urban area. Details are as follows.
As of 2020 before the end of September, the city mentioned standard transformation is completed with small boilers. Among them, the city center before the end of 2019 to complete the transformation mentioned standard, to Shanghai, "Boiler Air Pollutants Emission Standards" (DB31 / 3872018) requirements, to encourage compliance in advance.
In January 2018 - September 2020 period, complete boiler mentioned standard transformation and acceptance, discharge standards under the "50%, 75%" and other major conditions of the city's small and medium-load boiler unit.
City, District, together, support the implementation of fiscal policy. Giving special one-off subsidies, municipal and district levels in line with the financial support of the above-mentioned range. Specific binding transformation of the former boiler capacity and completion time, be supported in accordance with the following criteria:
How to select SZS SZS choose how gas steam boiler Gas steam boiler Gas steam boiler SZS how to choose? Different manufacturers of different capacity, different core technical mastery of different technical content of finished equipment, different performance. The quality and efficiency will be greatly reduced. In order to obtain high yields fundamentally, the choice SZS gas and steam boiler manufacturer, we select and purchase SZS gas and steam boiler manufacturer should be cautious. 1, excellent quality: our equipment select high quality steel, boiler and pressure vessel special steel, steel pipes with materials is GB 3087, carefully crafted by the workshop master superb casting process, the overall quality and performance facilities are guaranteed by 2, excellent performance: various types of gas steam boiler structural design calculations accurate, scientific and reasonable, adaptable, able to adapt to different production environments for a variety of materials; 3, the full model: we all have different gas bono energia boiler steam generator operating mode, different specifications for different scale of production. If your special production requirements, we also provide you with customized services for you to create the right model; 4, improve the service: we sell each piece of equipment to support life-long service, there will be an employee of the factory to guide you through the installation and commissioning of the plant, in order to ensure that the equipment can successfully put into use, post-production equipment failures occur after contact us and we will send someone to your door guide maintenance work, the worry-free production.
7) Steam from the steam drum is sent to the primary superheater.
8) Steam is super heated to a high temperature and pressure in the primary superheaters and then moves to the secondary superheaters.
9) In the secondary superheaters steam meets the very hot gases exiting the top of the boiler. The steam is heated to its final temperature and pressure before leaving the boiler as main steam. The main steam is sent to the high pressure steam turbine. The steam turbines drive a generator which produces electricity.
10)Steam exiting the high pressure steam turbine is called cold reheat. It is reheated in the reheater and sent back to the second steam turbine.
Relationship between generator capacity and boiler capacity
From the energy point of view, the power generation process of the power plant is essentially a process of energy conversion (chemical energy → thermal energy → kinetic energy → electrical energy).
