cement kilns energy recovery boiler

The WNS gas condensing cement kilns energy recovery boiler using advanced technology, full use of flue gas waste heat, the thermal efficiency can break over 100%; the premix while further use, and other advanced technology of FGR for flue gas recirculation for NOx processing by reducing NOx from different parts of emissions, ordered a low nitrogen boiler NOx <30mg / m³, in line with the most stringent emissions standards such as Beijing and other places in China. 2, double drum vertical type combustion chamber (referred SZS) 10 tons of steam gas boiler water

Chinese hot water cement kilns energy recovery boiler series of parameters are: rated thermal power 0.1-116MW, allowable working pressure 0.4-2.8MPa, rated water temperature 95-180 ℃. Low pressure hot water boiler for his work without the supervision and control of water level, so its structure is simple, easy operation and maintenance, ease of manufacture. But there are some special problems of work: hot water boiler must ensure that no vaporization occurs, in order to avoid water hammer; internal and external corrosion oxygen acid corrosion of Low Temperature more serious; sudden power outage, the pot water flow generated by vaporizing Wait. These issues must be considered in the structural design of the hot water boiler, manufacture and operation maintenance.

Condensing cement kilns energy recovery boiler thermal efficiency and Application Analysis: as compared to coal-fired boiler gas boiler greatest feature is significantly reduced emissions, almost no sulfur dioxide, nitrogen oxides, and carbon dioxide emissions were reduced by 45% and 52%; In addition, each of the combustion gas may 1g 2.25g produced water, water vapor in the flue gas volume composition ratio reaches 15% ~ 19%, which is 2 to 3 times the data coal-fired boilers. All the water in the boiler evaporate into water vapor with the flue gas emissions and take away a lot of latent heat of vaporization, which is the root cause of hair high and low natural gas heat difference 3700kJ / Nm3 of. Recovery of this part of the latent heat of vaporization is the most important way to improve the thermal efficiency of the gas boiler. Condensation core technology is to reduce the heat loss of the fuel combustion, efficient absorption of thermal energy generated by the fuel, and because the flue gas condensation in the flue gas to the condensed water collecting harmful substances, acidic substances and reduce other contaminants in the air emission.

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.
