cfbc boiler combustion system advantages

Recently, Jinan City, Shandong Province People's Government issued and implemented the "2018 Beijing and Tianjin and the surrounding regions - 2019 autumn and winter tackling air pollution comprehensive management action plan" to inform the implementation of the program, requires the consolidation of ambient air quality improvement achievements, promote air quality continues to improve. On October 1, 2018 to March 31, March 2019, and all the city county fine particulate matter (of PM2.5) mean concentrations fell more than 2%, severe pollution and over several days up declining.

"Implementation plan" will be based on four construction industry, energy, transport and land use optimization adjustments to promote clean heating, public transferrin, enterprises mentioned standard upgrade, dust remediation, focusing on the consolidation of "scattered pollution" enterprise comprehensive rectification results, ruthless grasping diesel trucks, industrial furnaces and rectification of volatile organic compounds, heavy pollution to the implementation of the weather in autumn and winter peak load shifting production to strengthen joint prevention and control among regions, strengthen law enforcement supervision.

1, continued implementation of the total coal consumption control, strict implementation of national, provincial coal consumption reduction of about alternative work arrangements, and the development of alternatives seriously implement the Jinan City, the work reduction of coal consumption, coal consumption control tasks break down into individual counties, total coal consumption to achieve a steady decline. 2018, the city's total coal consumption control in less than 17.14 million tons.

2, effectively promote clean heating to the town (street) or the county as a unit as a whole. As of 2020, the city's pre-season heating living and improve the basic motivation for heating coal for alternative tasks, to develop a three-year implementation program to determine the annual task of governance. Taking into account the agricultural greenhouses, animal building bulk coal governance and to proceed with energy-saving buildings to improve energy efficiency. The county should proceed from reality, according to local conditions, reasonably determine the transformation of technical route, should the electric power, gas should the gas, the coal should be coal, should be hot is hot, and actively promote the use of solar thermal and centralized biomass utilization; adhere to highlight focus, give priority to urban life and motivation for heating gas demand, priority to promoting the urban bulk coal cleared. Gas will adhere to the reform, to change the electric set, on the basis of priority to the protection of residents in 2017 has started "coal to gas," "coal to electricity" project on gas electricity, gas and new year according to the actual supply and heating period the ability to reasonably determine the residents' coal to gas, "" coal to electricity "households; insist on legislation after the break, substitution of gas for coal to electricity instead of coal and other alternatives, in the implementation of air power is not the case, the original heating facilities will not be removed. In accordance with national, provincial requirements, to complete the clean winter heating construction tasks 33000.

3, complete replacement of the bulk coal areas to be designated as high-pollution fuel combustion zone ban in accordance with the provisions, shall not be burning coal for use again. Severely crack down on sales of low quality coal combustion, to ensure the quality of coal used in line with national and local coal quality standards.

The importance and necessity of the importance and necessity of industrial cfbc boiler combustion system advantages inspection cycle of periodic inspection of industrial boilers. Industrial boilers to provide steam and hot water production for industrial boiler or everyday use. Generally refers to a pressure less than or equal to the rated working 2.5MPa boiler. Internal inspection of industrial boilers, industrial boilers is the condition of the process of life, from time to time, request a regular boiler inspection rules "of the boiler furnace safety checks. Therefore, the findings may affect the safe operation of the various defects of industrial boilers, and take effective measures to eliminate or use the direct monitoring of industrial boilers or stop using industrial boilers, prevent accidents and ensure safe operation of the boiler. China is the world's largest country industrial boilers, internal inspection to determine the reasonable period of industrial boilers is very important. In the current boiler periodic inspection rules "(hereinafter referred to as the inspection rules boiler), industrial boiler internal inspection cycle is based on each industrial boilers conclusions of the examination is certain: the conclusion of the test is allowed to run, usually every two years. Inspection findings after running rectification, the rectification to determine the test cycle is complete, restrictions conclusions of the examination running test cycle needs to be shortened. According to inspection and use of maneuverability, the shortest cycle is generally six months, and the longest period is set to two years, which is prescribed to check the boiler within a predetermined range. Users want to check a longer period, in order to save costs and reduce downtime inspection; inspection agency hopes to shorten the inspection intervals to reduce detection risk, increase revenue inspection; regulators want companies to maintain the safety in production. Efforts to reduce the burden on businesses. Objectively speaking, the shorter the trial period, the smaller the risk, the higher the socio-economic costs; the longer the trial period, the greater the risk, the lower the social and economic costs. Rationally defined internal inspection cycle industrial boilers, to ensure safe operation of the boiler, can also reduce the social and economic costs.

10 tph SZL biomass-fired water tube cfbc boiler combustion system advantages project for paper industryPaper Industry is one of the industries which needs boiler plants most. Steam boilers are used to provide steam in drying, bleaching, concentration and other production process of paper industry. Yili TECHNOLOGY Co.,Ltd., founded in 2006 in Hubei province, is a professional paper mill producing abrasive base paper, insulating paper board and cable paper with pulp board. With the rapid expansion of business, the paper mill's demand for steam is increased by years. In order to enlarge the production scale, the company planned to order one set of new steam boiler. Considering the green development is the main trend in the future, the company has made a decision to use biomass particle as boiler fuel. The company ultimately chose ZOZEN as its biomass-fired boiler supplier after several comparative studies. The biomass-fired boiler built by ZOZEN has unique design structure and production technology, and takes the lead in solving the commonly occurred problems in traditional biomass-fired boilers, such as furnace arch burning down, furnace door burning out, hopper catching fire and stopper coking. Furthermore, it has gained a public praise with its outstanding safe, efficient, energy-saving and environmental protection features. The sales manager of ZOZEN recommended the SZL series biomass-fired boiler to the company based on the understanding their requirements. This boiler not only has the above advantages, but also has the compact design as a package boiler, which has the benefits of convenient field installation, short production period and low cost. All above features have fully met the company’s emergency requirements of production line.
