In Bahamas, the biomass can be burned using conventional combustion technology like grate furnace or fluidized bed boilers. For power generation the biomass would be charged to the furnace of a steam boiler.Steam produces by the boiler will then drive a steam turbine generator to generate electricity. The typical capacity range for biomass power plants 1-20MW.
Recently, Beihai City, Guangxi Province, issued a notice of Beihai City in Spring 2019, the comprehensive management of tackling air pollution control action program (hereinafter referred to as "Notice"), mainly for the further implement the State Council "to win the Battle of Blue Sky three-year action plan" " Guangxi tackling air pollution control three-year operational plan (2018-2020 years) "and" Guangxi 2019 spring tackling air pollution control comprehensive management action plan "to complete the Beihai tackling air pollution control tasks and achieve the 2019 goal of improving the quality of atmospheric environment.
First, the key tasks
1, and comprehensive utilization of straw Jinshao special action. County area to develop and implement straw Jinshao work program, refinement department, streets, towns, villages regulatory responsibility, the implementation of "fixed, regular, fixed people, will be responsible for" management and control, establish full coverage, no dead ends grid of the regulatory system, full use of the overhead video, satellite remote sensing, unmanned aerial vehicles inspections, straw burning a variety of means to closely monitor the information grid monitoring platform. Strengthen the inspection of law enforcement inspection, severely crack down on open burning of straw behavior. Increase efforts to promote comprehensive utilization technology of straw, conditional county incentives to take subsidies. Focus on sugarcane crop leaf prohibiting the work, in accordance with the principle of territorial management, the development of sugar cane leaves prohibiting management program, to strengthen the unified management, unified utilization, unified treatment and disposal. Municipal Agricultural Bureau, the Municipal Office of the sugar industry to strengthen guidance and support for the comprehensive development of the use of sugar cane leaves, the full implementation of mechanized harvesting of sugarcane, sugar cane fields and comprehensive utilization of straw has broken.
2, urban dust comprehensive management of special operations. The urban dust control content into the focus of supervision and improve the system of dust control mechanisms, the establishment of the construction site with information technology platform construction, water conservancy projects, the implementation of dynamic site inventory management. Supervise the implementation of the site around the site enclosure, stockpiling cover, wet earth excavation work, the main road hardening, cleaning out the vehicle, sediment transport vehicles sealed "six percent", temporarily unable to start construction land should be covered. The construction site dust pollution prevention and control into the "civilized construction" category management, dust control costs are included in the project cost; according to the law will not be in place of harmful dust management information into the construction market credit management system, in serious cases, be included in the construction market players " blacklist". Rinse vigorously promote road sweeping mechanized operations, improve road mechanized cleaning of urban built-up area. Sediment transport, coal, ore, gravel and other transportation vehicle is not confined to do, strictly punished according to law.
3, industrial enterprises air pollution comprehensive management of special operations. According to Beihai City "scattered pollution" inventory accounting, to further improve that standard and rectification requirements, classification of promoting the "messy dirty" business regulation, focusing on remediation of the city and the surrounding "messy dirty" business. Strengthen the coal-fired boilers (including biomass boilers) and brick, ceramics and other industries industrial furnaces supervision, strengthen law enforcement. Encryption of iron and steel, building materials, nonferrous metals, thermal power, cement, brick, calcium carbonate and other business materials (waste) storage, handling, crushing, transportation and other aspects of the inspection frequency of inspections, strict implementation of consecutive daily penalties, limited production shutdown and other means strictly according to law penalties for environmental violations. Focus sessions focused their attention on the process of pollution, thermal power, steel, cement, bricks, ceramics, wood processing, sugar high emission enterprises, especially in built-up urban area of business, and strictly control the total amount of air pollutant emissions.
When the boiler leakage occurs electric heating boiler is how to protect? Electric steam boiler is electrically heated steam boiler, simply the electric steam boiler is heated, in particular to a glow into thermal energy so as to heat water to generate steam pressure vessel. State Technical Supervision definition of electric steam boilers are: the volume of water in the highest security level greater than or equal pressure electric steam boiler 30L is electrically heated steam boiler; electric steam boiler pressure is less than 30L electric waste steam generator manufacturing and use without technical supervision departments to monitor inspection and approval.
In order to prevent spontaneous combustion of carbon black oil scale accumulated on economizers and air preheaters, steam soot blowers should be added to these parts to keep the heating surfaces clean. At the same time, because the fuel oil does not form coke slag, membrane water-cooled wall can be used to form a micro-positive pressure boiler (500 x 1000 cow / m). It can save the draft fan, only the fan can exhaust the flue gas out of the furnace. If the whole shell of the boiler is made of thick steel plate, it can also be made into a positive pressure (0.3 ~ 0.6 MPA) boiler, which can make the whole structure of the boiler more compact, and is more used in the gas-steam combined cycle generator set.
