china made coal hot water boiler

Industrial boilers and heating boilers What is the difference? Industrial boiler product in two ways, one steam used to generate electricity or gas, such as steam vaporized available fertilizer plant, coal as raw material, synthetic fertilizers, which is typical of industrial boilers, coal-fired industrial boilers still account for a large most gas is generally waste heat boiler for recovering waste heat. Industrial boilers commonly circulating fluidized bed boiler industrial boiler thermal power equipment is important, our country is today the world's largest production and use of boilers country. China's manufacturing industry is established and developed after the founding of New China. The term "industrial boiler" in the late 1930s, with the boiler thermal power generating units with capacity increasing, in order to distinguish high-capacity power plant boiler gradually adopted. Modern large-scale industrial boilers evaporation capacity has reached 100 to 200 tons / hour. Industrial boiler structure type in the structure can be divided into fire cartridge type, water and fire tube type 3 class. ① fire tube boilers; it is an early boilers, fire tube containing only water in the boiler twelve heating pot shell fire cylinder combustion means. Low thermal efficiency, large volume and steel consumption, since substantially no production 60s. ② fire tube boiler: it is in the vertical or horizontal potshell in addition to the fire tube, a plurality of means further smoke tube. The fuel in the combustion chamber high temperature flue gas produced after combustion smoke flows through these pipes heating pot of water, and then discharged into the chimney. Compared with fire tube boiler, since it is the number of multi-smoke tube, heated area increases, the exhaust gas temperature is low, high thermal efficiency, and the consumption of steel are relatively small volume of the boiler. FIG. 1 is a horizontal tempering tube boiler. When evaporation fire tube boiler is generally not more than 15 t /, working pressure not greater than 1.6 MPa, the thermal efficiency of coal is generally about 70%, of all oil-fired boiler automatic operation, the thermal efficiency can reach 85%. ③ water tube boilers: mostly used for larger capacity, higher pressure industrial boilers. Water tube boiler has a natural circulation type and DC two. Natural circulation water tube boiler with a single drum and double drum and other structures. Figure 2 is a double drum water tube boiler. Such boilers generally disposed in the convection tube economizer, an air preheater and sometimes, in order to reduce exhaust gas temperature. When coal efficiency up to 80% higher when the fuel. No drum DC industrial boilers, and the tubing coiled behind the inner wall of the furnace tubes of the convection heating surface composition. From the end of the tube into the water supply, the steam output from the other end. Industrial boilers small current, typically with separator and automatic control devices. The fuel and fuel combustion equipment is widely used in variety of industrial boilers, coal (bituminous coal, anthracite, lignite and coal waste, etc.), oil (heavy oil, residual oil and diesel, etc.), gas (natural gas or various industrial by-product gas) plant and urban waste (wood, bagasse, black liquor and waste, etc.) and so on. Therefore, industrial boiler combustion equipment is also varied. There layer belongs chain grate combustion apparatus, the feed grate, reciprocating grate, vibrating grate, chain grate stoker plus the like (see grate). Also useful way of fluidized bed combustion (see boiling furnace). In the evaporation of 65 t / h coal-fired industrial or larger capacity boilers generally use coal. Heating boilers boiler belongs to the category of civilian life, as people's safety awareness, and after 2000 are based on building heating hot water as heat medium, it does not allow the use of steam boilers, so in general we are talking about heating boilers often refers to pressure china made coal hot water boiler. There are many types of heating boilers, their classification is mainly divided in accordance with the fuel type, fuel heating boilers can be divided according to the different electric heating boiler, oil heating boiler, gas heating boilers, coal-fired heating boilers, biomass heating boilers. Which includes fuel: diesel, kerosene and heavy oil; which includes gas: Natural gas, LPG, city gas and biogas.

Gas boiler refers to a container for generating steam and hot water from natural gas(Calorific value 10000 kcal/Nm³), LPG(Calorific value 22929 kcal/Nm³), artificial gas(such as city coal gas, Calorific value 3000-4000 kcal/Nm³), biogas(Calorific value 5200-6000 kcal/Nm³) and other fuels. In general, gas boilers are usually packaged boilers.

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.

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.

Boiler structure have? The whole structure, including boiler and boiler auxiliary equipment of two parts. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. The furnace cross-section is generally square or rectangular. Combustion fuel to form a flame in the furnace and high temperature flue gas, so the hearth around the furnace wall is made of refractory material and insulation material. On the inner surface of the wall of the furnace waterwall tubes often laid, it will not burn both protect the furnace wall, and absorb a large amount of radiation heat of the flame and the high temperature flue gas. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler should be fueled with the original design of the fuel. Boilers running economy and reliability are likely to vary greatly reduced when using the characteristics of fuel combustion. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler.
