Steam 0 8t h boiler must be shut down? For gas-fired boiler will be some companies: the higher cost of oil-fired boilers and electric heating boilers, many SMEs simply can not afford, the thermal efficiency of the boiler is too low, gas consumption often can not keep up. Many reasons why gas boiler known as the preferred place of the main gas boiler. In business consulting to some customers learned, after being forced to shut down the gas boiler, no steam, the company has only discontinued. In order to survive companies only replace the boiler, to select the gas-fired, oil-fired boiler, electric heating boiler and a biomass pellet boiler. Currently the market for natural gas boilers only major selection, analysis of the reasons is that gas-fired gas boiler is fully automatic, with no pollution. But in reality, many businesses faced to replace the boiler, gas pipeline did not pull in place, some companies simply do not have natural gas pipeline, steam boiler must be shut down? Gas boiler gas boiler, not to mention the natural ventilation. This is the biggest obstacle currently facing.

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.

The main role of the auxiliary 0 8t h boiler is the effect of several auxiliary boiler auxiliary boiler combustion, are mainly the following: (1) primary fan: drying of fuel, the fuel supplied into the furnace, generally a centrifugal fan; (2) blower: to overcome the air preheater, duct resistance of the burner, combustion air delivery, fuel combustion is maintained; (3) drawing fan: negative flue gases, maintain the chamber pressure, a flow of flue gas, flue gas and air to complete heat exchange; (4) mill: the pulverized coal pulverized coal fineness required, the thickness of the completion of drying and powder separation; (5) a sealing fan: providing a certain air pressure, to prevent powder leakage mill. Stoker: coal, and controlling the amount of coal; (6) Electrostatic precipitator: Dust Removal System: residue positions, machine slag, slag crusher, bucket elevator, wetting mixer, bag filter, automotive bulk machine Of course, in addition to fire detection blower, air compressor, a given row, even row, pumps.

After completion of the gas 0 8t h boiler cleaning, be sure to use hot air to dry them, but not both for heating the furnace walls and other accessories, this is likely to have adverse consequences. Right way is to place an electric heater in the bottom of the gas boiler, heated.
