Recently, Shaanxi Province, to build a good ecological environment, issued a "Blue Sky Battle Shaanxi Province 2019 work program", "clear water Battle of Shaanxi Province 2019 work program", "Shaanxi Province Pure Land Battle 2019 work program", "Shaanxi Castle battle province 2019 work program "and other four major environmental battle to defend the program. Details below.
"Program" is mentioned: this year by optimizing the six policies, tough fight seven games, seven strengthen security measures, the average concentration in urban areas and strive to fine particulate matter (PM2.5) fell 4 percent to ensure that the number of heavy pollution days significantly reduce atmospheric environmental quality improved significantly, people's happiness significantly enhanced blue sky.
3, increase economic policy support to accelerate clean winter heating work, in accordance with the principle of "Jiangyoufalie", the establishment of special funds for air pollution prevention and control arrangements with local ambient air quality to improve performance linkage mechanism.
1, lay the tough restructuring, according to the law closed down quit a number of energy consumption, environmental protection, safety, technology and production of non-compliance or substandard products out of production capacity, before the end of the year, the Guanzhong area basically completed "messy dirty" industrial enterprises and in accordance with regulations cluster comprehensive treatment.
2, tough fight industrial pollution control, focusing on gas-related industrial pollution sources to perform all the installation of flue gas emission standards new online monitoring facilities, the Guanzhong area cement, coke, iron and steel, nonferrous metals, glass, ceramics, tile and other industries, and to ban coal-fired hot air furnace, the coal-fired cogeneration substantially eliminated heating pipe network coverage heating, drying furnace (kiln).
4, clean energy alternatives tough fight, central heating station complete transformation of existing coal-fired clean off the area before the end of the city to clean the heating rate in urban areas off more than 90% before the end of May to complete the Guanzhong area rural village set loose coal governance indeed household inventory; motor vehicle pollution control tough fight, and increase freight railway construction investment, strengthen the construction of urban public transport system, promote high-emission motor vehicle pollution control, Guanzhong area cities and built-up area buses in the proportion of new energy vehicles to achieve 80 %, starting July 1, the province's implementation of six national emissions standards.
"Program" also pointed out that by strengthening the organizational leadership, strengthen environmental law enforcement, special inspectors carry out inspections of air pollution, strengthen grid environment supervision, improve environmental monitoring and control network, strengthen science and technology infrastructure support, strict accountability assessment 7 safeguards to ensure that work effectively.
Gas-fired steam boiler plant accident management system, equipment or components of the gas steam boiler damage due to abnormal loss of accuracy, reach the level of accidents is the equipment failure. 2. The main gas steam boiler equipment failure rate evaluation, the failure rate under 23%. 3, less maintenance costs of a gas steam boiler of a device for the 500≤1000 yuan. Gas large sized hot water boiler with environmental protection, energy conservation, safety, salient features fully automatic operation, and ease of use. In addition, due to the operation of the economy, government policies to encourage, gas hot water boiler more and more people of all ages. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Small, large, thin device 1000≤ membered or power outages caused by equipment failure company 10 minutes 30 minutes belong to ordinary accident. 4. Gas-fired steam boiler single piece of equipment maintenance costs more than 10,000 yuan, fine, big, thin device more than 30,000 yuan, or due to an accident caused power outages company for more than 30 minutes. The single gas steam boiler equipment maintenance costs more than 500,000 yuan, or accident due to equipment being shut down more than two days, shut down more than a week. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. 6. Gas-fired steam boiler equipment accident occurs, stop immediately and on-site maintenance. Operator shall immediately report to the workshop, the workshop should be reported immediately to the production department, production department shall, jointly with relevant departments to seriously inspect the site. Responsibility to identify and deal with. When major or serious accident, the production department should ensure quality engineer reported within two hours. 7. Gas-fired steam boiler equipment accidents occur, three things must adhere to the principle of letting go (ie the cause of the accident is unknown, the responsibility for the accident and the masses have no education, no preventive measures), identify the causes and responsibilities, based on the circumstances giving administrative sanctions or financial compensation to punish people break the law according to the law.
Gas Steam Boiler Water Wall Tube Explosion Analysis and Processing With the west-east gas project in-depth and complete, and the "coal to gas," the implementation of Beijing, Urumqi, Daqing and other cities and district heating heat source to promote the use of gas-fired boiler . More commonly used gas-fired boiler type D, type 0, A-type, p-type [1-2], these four basic types of furnaces by dividing the furnace cross-sectional shape. Wherein, D, 0, A-type small capacity boilers belonging horizontal boiler, boiler Ding is a large vertical boiler. The four furnaces are used membrane wall structure, eliminating the flue gas leak, reduce heat loss and improve the thermal efficiency of the boiler, ensure the stability of the structure. A compact, short installation period, high thermal efficiency, low noise, low energy consumption, low emissions, long life (design life 30a), adaptable load fluctuations and other characteristics can be controlled by computer program running faults and Protective function. Domestic slightly less than the amount of evaporation experience in the development of high-power gas steam boiler in the 75t / h or more, most of the development work is based on the introduction of Europe and learn from small gas steam boiler above. China's own design of high-power gas steam boiler in the course of running more than a vibration, burst pipes and other problems. This paper discusses some evaporation of the squib causes and treatment of boiler waterwall 160t / h of a gas steam.
