25 tph SZS gas-fired automatic dzl coal fired steam boiler for cigarette factoryFrom 2014, Baoji City began to implement natural gas projects and vigorously implemented coal-to-gas conversion projects. Baoji Cigarette Factory is one of the major backbone enterprises of the China National Tobacco Corporation and is the largest cigarette manufacturer in the northwest region. In line with the environmental protection policy, Baoji Cigarette Factory implemented the "coal to gas" project. Through bidding activities, it cooperated with ZOZEN boiler to dismantle 35 tph coal-fired boilers and install 25 tph SZS gas-fired steam boilers to improve boiler operation levels and reduce air pollutant emissions.

January first, Henan Province issued "the transformation of traditional coal chemical industry development action plan" (the "Program"), to promote the province's pollution prevention campaign of three-year action plan to speed up the traditional coal chemical industry (ammonia, methanol) industry to green transformation, to achieve high-quality development.

First, strictly control new capacity

Adherence to the red line capacity, traditional coal chemical enterprises prohibit new construction, new capacity expansion projects alone, is strictly prohibited without permission around the building does not meet the requirements of the industrial layout plan of coal chemical project in principle. The province's coal chemical projects and intensive clean-up, but according to the specified time limit has been approved to start construction of the project in principle, to construction, relocation and renovation projects must be upgraded into the base or campus planning. By 2020, the chemical industry out of the fixed bed coal gasifier intermittent exit single set of devices 300,000 tons / year of synthetic ammonia production capacity. Strict safety, fire safety, environmental protection, energy saving, water administrative licensing, implementation of the project safety, environmental protection facilities "three simultaneous" (designed, constructed and put into use) system, and resolutely shut down energy consumption, environmental protection, safety, quality, technical non-compliance enterprise. Strict implementation of the regional total energy consumption, pollutant emissions control requirements, upgrading of coal coal project be implemented reduction or equivalent alternative.

Second, increase the relocation and reconstruction efforts

Further promote the densely populated towns of dangerous chemicals production enterprises and urban built-up areas heavily polluting industrial relocation of enterprises, the implementation of an intensive investigation, the establishment of management accounting, according to "a business a policy" during mode classification advance. Priority to promoting the urban area of ​​coal chemical industry relocation, conversion or quit, not in the urban area but not in the business park to gradually move the park, according to the specified execution be discontinued or phased out. Close to exit the business enterprise to achieve the "two off three clear" (cut industrial water, electricity, removal of raw materials, products, production equipment), select the transformation of the enterprise to implement the upgrading of the standard industry benchmark, to off-site relocation According to large-scale, modern principles move into the province for involving chemical industry gathering area. Relocation upgrading of enterprises, projects and equipment should be encouraged to reach equipment industry access standards and conditions specified in the Guiding Catalog of Industrial Structure Adjustment, the use of large-scale continuous pressurized gasification plant, ammonia production capacity to 300,000 tons / year and above, coal methanol production capacity reached 100 million tons / year and above, the main push large-scale equipment.

Third, the implementation of green transformation

Before the end of 2019, coal chemical enterprises fully completed VOCs governance. And comprehensively promote the chemical industry equipment static and dynamic sealing points, storage, handling, waste water systems, unorganized process emissions and non-normal operating conditions and other root causes of remediation. As requested, the timely completion of the coal chemical industry waste discharge permit issued by the work, companies must comply with the behavior of the sewage discharge permit clear conditions, various types of environmental inspection found violations, strictly and severely investigated and dealt with as soon as possible in place. Based on "clean production audit approach", the implementation of coal chemical enterprises compulsory clean production audit coverage. Required to implement risk control measures to close the relocation of enterprises left over land.

If you know a little about chemistry, you may know that the sulfur content of oil and coal is roughly equal, but ask what low-temperature corrosion of oil-fired boilers is much more serious than coal-fired boilers, for two main reasons:

1. 90% of ash in coal-fired boiler, especially coal powder furnace, is taken away by flue gas, sulphuric acid steam formed in flue gas is absorbed by fly ash in flue gas, so that sulfuric acid vapor in flue gas is reduced, and about half of sulfur remains in ash when coal is burned. When the oil is burning, the sulfur content in the fuel almost all changes to the ash in the SO2, fuel, the fly ash in the flue gas is very little, and the adsorption ability to the sulphuric acid vapor in the flue gas is very weak.

2. The hydrogen content of oil in the oil-fired boiler is about 11%-12%. The combustion of each ton of fuel oil can produce about 1 ton of water vapor, and the partial pressure of steam in the flue gas is higher than that in the case of coal-burning.

Electric automatic dzl coal fired steam boiler combustion efficiency and how to save more: In China container industry is a growing industry, and container industries and enterprises are also faced with various challenges. Container industry must adhere to market-oriented strategy, closely rely on scientific and technological progress, scientific and technological innovation, under the guidance of national energy and environmental policy, company structure and product structure adjustment, manufacture and sale of container in line with market demand, occupancy in the fierce competition in the market place. Electric steam boiler to improve the combustion efficiency, saving fuel, the fuel quality should be controlled, uniform atomization burner. To achieve the above object, the following points should be noted: 1 to understand the combustion principle, adjusting the wind ratio of positive oil (gas), to achieve efficient combustion; 2, to maintain a good working condition of the nozzle, the nozzle is not easy too large or too small, the nozzle wear obstruction, carbon status, to ensure good atomization combustion conditions. 3, to maintain proper pressure or hydraulic, pneumatic or steam boilers, such as high or low oil pressure, and a hydraulic or pneumatic pressure is too large or too small, will affect the mixing of fuel and air uniformly. 4, to adjust the burner flame length brains spray angle size and shape of the combustion chamber with fire furnace chamber filled eye, achieve economic combustion. No black smoke, no soot, in the good sense of the coming year running.
