high pressure boiler generates steam
Recently, we learned, Shaoxing City, Zhejiang Province People's Government Office issued the "coastal city 2018--2019 autumn and winter tackling air pollution comprehensive management action plan", as follows.
Less adopt comprehensive measures to reduce coal total coal consumption, coal consumption in 2018 to ensure that the total amount of negative growth. New non-owned coal-fired units, the implementation of new large-scale coal-fired units and coal consumption capacity equal or reduction alternative.
Optimize the use of natural gas structure, in principle, to new natural gas cogeneration and gas chemical projects, gas will adhere to the reform, orderly manner "coal to gas" project.
Carry out boiler (with tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities) an intensive investigation to establish accounting and inventory management, to develop a comprehensive remediation program in accordance with the unified deployment requirements boiler city, according to the law in accordance with regulations to increase fuel coal boiler out of efforts to achieve all cleared 10 steam tons / hour and coal-fired boilers to prevent high-polluting fuel boiler rebound has been eliminated. Boiler registration strictly prohibit new steam per hour 35 tons / hour of coal-fired boilers, coal-fired boilers new emission concentration to meet ultra-low emission of air pollutants, strict control of new biomass boilers, coal-fired boilers embodiments and low nitrogen urban built-up area of ultra-low emission biomass boilers transformation.
Similarities and differences hot water high pressure boiler generates steam and steam boiler Analysis: The boiler is divided according to media can be divided into hot water boilers and steam boilers, similarities between the two are based on water as the working fluid it, their similarities and differences where is it? 1. comparison of the two, the biggest difference is that the former is the production of hot water, which produced steam. 2. Steam boiler pressure vessel belongs to the class, and there is no hot water boiler pressure, so go through the formalities in this one, hot water boiler is relatively advantageous. 3. Both heat as a heat medium, the former low exhaust gas temperature, the thermal efficiency of the boiler is relatively high; the boiler water in the lower water quality requirements, less treatment costs.
Heating surface modification, how to deal with: For high pressure boiler generates steams heating surface generally refers to a side in contact with flames or smoke metal surface area (the other side in contact with water or heat transfer oil), is the primary location of the heat exchanger.
Currently the world's main method to reduce NOX emissions from the power plant high pressure boiler generates steam can be broadly divided into the following well-established four categories:
