Depending on the system used, 30–45 kWh/t clinker can be generated, which is up to 30 % of the electrical power requirement of a cement plant. Waste Heat Recovery Boiler is a system which recovers various kinds of waste heat generated from the production process of steel, non-ferrous metal, chemical, cement etc and those equipment of industrial furnaces, refuse incinerators, industrial waste incinerators, and convert such recovered heat into useful and effective thermal energy. Waste Heat Recovery Boiler is contributing to industrial society in terms of improvement of thermal efficiency, energy saving, environmental protection etc.
Recently, the State Administration of China's market, the National Development and Reform Commission, Ministry of Ecology Environment jointly issued the "Notice on Strengthening Environmental Protection and Energy boilers" (the "Notice"), put forward specific requirements for environmental aspects of energy-saving boiler work.
"Notice" the implementation of the guidance, "the CPC Central Committee and State Council on the overall strengthening of environmental protection and resolutely fight tough fight pollution prevention advice" and other documents, adhere to safety first, prevention first, the five principles of energy saving, comprehensive management implement energy saving boiler from the production, import, sale, use and other aspects of business to post the main responsibility, and strengthen supervision and management of Eng environmental Protection in the "special equipment Catalog" range of boilers, and comprehensively promote energy-saving environmental governance boiler.
First, across the country, in principle, to a new 10 steam tons / hour of coal-fired boilers and, in key areas (and the surrounding areas of Beijing, Tianjin, the Yangtze River Delta region and Fenwei plain) and the rest of the city built the county level and above New District, in principle, to 35 tons of steam / hour of coal-fired boilers.
Second, the new coal-fired boiler emission concentration of air pollutants key areas need to meet ultra-low emission (6% on the basis of the reference oxygen, soot, sulfur dioxide, nitrogen oxides emission concentration of not more than 10,35,50 mg / m) requirements.
Third, the area reserved execution key boiler air pollutant emission limits or special places more stringent emission standards, 65 t steam / hour coal-fired boiler and above all of the ultra-low emissions and energy transformation embodiments, a low nitrogen gas boiler is substantially complete transformation.
"Notice" also stressed the upgrade boilers with energy and environmental conservation requirements. Boiler units to implement the main responsibility for ensuring that the boiler energy efficiency and emissions of air pollutants meet legal regulations, technical specifications and requirements of the relevant standards in China.
Fourth, for the boilers do not meet environmental requirements, and use shall take appropriate measures for improvement, if after rectification not meet the requirements, be allowed to continue to use.
Fifth, the boiler unit to apply for emission permits in accordance with laws and regulations, and to establish their own monitoring system, strict discipline and preservation of the environment management accounting, timely and relevant departments to prepare and submit emission permits implementation report.
Sixth, the boiler unit to promptly take the initiative to report the boiler equipment obsolete, and apply for cancellation of the boiler use registration shall not be obsolete boilers to move equipment or put into use again.
The purpose salt water boiler and boiler coal consumption Description: boiler water, which is why salt? 10 tons of boiler, if its calorific value is 5000 kcal, then its coal consumption is how much? In addition, some difficult questions about the boiler, which also need to be answered and solved? We ask these questions, mainly to elicit content of the article, at the same time, we will also know what to say, so as to carry out targeted learn more, improve their learning efficiency. 1. Why is salt water boiler? Boiler water and salt, which is mainly for two purposes, one is to increase the water temperature and the boiling point, and sterilization for this purpose can be achieved. If a heating boiler, it can also be beneficial to provide heating. Second, it is used to soften hard water variety, so there may be good quality, to prevent the generation of scale in the boiler, in turn, affect the normal operation of the boiler. 2.10 tons of boiler, its calorific value is 5000 kcal, then, is how much of its coal consumption is? 10 tons of boiler, its calorific value is 5000 kcal, then its coal consumption per hour is about 1.85 tons, that is 185 kg. While its coal consumption, this value is multiplied by the boiler sucked day's work time, so you can get the specific values. But note that, because there are some objective factors, so this is just an estimate, which may be some difference between the actual value.
Boiler economizer tube is damaged how to do? Damage is divided into: (1) decreased water level, water flow is abnormally greater than the steam flow. There are different sound nearby (2) boiler economizer. (3) Leakage of the lower portion of the furnace wall and economizer preheater transitions have steaming, wet ash hopper phenomenon. (4) both economizer flue gas temperature difference is increased, a low flue gas temperature of side leakage. (5) economizer import and export pressure drop. Processing method: if the damage is not serious, should return monitor, value of the long, reducing the furnace load, the feedwater automatic to manual, and notifies the turbine by opening feed pump reinforcing feedwater, stable combustion, to strengthen the inspection and monitoring of the fault point, do good physical security measures to prevent, maintain a short run, reporting chief engineer, asked the shutdown. When approaching if endanger or affect the operation of the furnace inlet pipe, or despite increased water, or drum level decreases rapidly, should an emergency shutdown, the shutdown prohibition of open recirculation door.
Apr 03, 2018 · Many water heaters develop leaks at the pipe connections on top. Manufacturers usually provide two special steel pipe fittings that are threaded into the top of the steel tank. Its typical for steel water heater tanks to have the cold water inlet pipe and the hot water outlet pipe connected to these fittings using copper fittings and pipes.Get A Quote
