uses of plc in a boiler

What are the conditions so that the uses of plc in a boiler can burn fully as we all know, if the boiler combustion, can save a lot of fuel, and combustion efficiency and improve efficiency in the use of the boiler, you can save the cost. But in reality there are boiler combustion process is not fully burn, so what conditions the boiler can burn it fully? Because burning is a complex physical and chemical processes, combustion speed depending on the chemical reaction of fuel and oxygen as well as oxygen and speed contacting and mixing speed combustibles. (Combustion speed per unit time reflects the number of burning off the combustible material.) The former is called the chemical reaction, also known as chemical conditions; the latter is called a physical mixing speed, also referred to as physical conditions. Only in the case of chemical conditions and physical conditions are more compatible in order to obtain a faster burning speed. Combustion is possible to sufficiently and quickly conditions are: (1) relatively high furnace temperature, the temperature of the chemical reaction is the basic condition of combustion. It fuels the fire, combustion stability and burnout have a great impact. Maintain the proper temperature in the furnace is very important. Of course, when the furnace temperature is too high, consider the problem of slagging boilers. (2) a sufficient amount of air supply air supply to provide sufficient oxygen for the fuel, which is the initial condition of the combustion reaction. If the air supply is insufficient, the fuel can not get enough oxygen, you can not achieve complete combustion. However, excessive amounts of air will cause the furnace temperature to decrease and increase the exhaust loss. (3) good mixing conditions, sufficient air to provide sufficient oxygen to supply the fuel, which is the initial condition of the combustion reaction. If the air supply is insufficient, the fuel can not get enough oxygen, you can not achieve complete combustion. However, excessive amounts of air will cause the furnace temperature to decrease and increase the exhaust loss. (4) a sufficient time to burn the fuel in the furnace for a time sufficient to achieve a high burn-up fuel, which is a sufficiently large furnace volume. Proportional to the volume of the furnace and boiler capacity. Of course, also related to the volume of the furnace with the combustion characteristics of the fuel. For easy to burn the fuel, a relatively small volume of the furnace. For example, for the same capacity furnace boiler fuel burner furnace volume smaller than the volume of the pulverized coal, and smokeless coal furnace volume dispersion furnace volume slightly larger than the cigarette coal stove.

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.

SZS double drum uses of plc in a boiler’s advantages

double drum boiler's advantages

1.D-type Double-Drum style with compact structure, less occupied area, good flame fullness which is better for low nitrogen combustion and low nitrogen emission.

2.The rear section of such boiler is equipped with flue gas condensing and recovery device which can effectively control exhaust gas temperature so that to improve boiler thermal efficiency.

3.Adopts high heat resistance material as adiabatic layer which brings a good thermal insulation property; the outer shell of the boiler adopts pressed guard board which makes the boiler looks delicate.

Meanwhile, the fast side condensing gas uses of plc in a boiler, can be used as an independent source of central heating station, a good regional heat supply solutions. Boiler module formed by a plurality of independent modules premix composition preassembled, and great compatibility adjustability.
