For subcritical pressure natural circulation boilers and the control loop, to prevent premature film boiling, heat the mixture to delay the deterioration of soda, high thermal load in the furnace burner area is disposed, the use of internally threaded tube instead of the smooth inner wall of the light pipe to manufacture water wall.
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.
What matters when pharmaceutical boiler tube maintenance works maintenance boiler maintenance should be noted that pharmaceutical matters need attention are what pharmaceutical factory boiler after running for some time, is inevitable to carry out a series of maintenance work, maintenance, etc., then conducting such work what kinds of details need to pay attention to it? the following small series bring you a simple understanding. (1) In the process of maintenance, the maintenance work to have the support of the operating environment and conditions, if there is a lack of conditions should be specific conditions, to create a feasibility conditions. Before (2) Maintenance start, try to ensure that the boiler is in shutdown state, but without water, electricity, etc., in order to avoid the repair process, the occurrence of unnecessary accidents. (3) during repair, maintenance tools should regulate different place, count the number of use, so as to avoid errors by the operator, the tool is not left in the furnace or other suitable place. (4) after the repair work, be sure to carefully inspect the site, if necessary, simple operation and commissioning, to ensure that after a brief qualified operating personnel before leaving the venue. (5) The last point is that after the repair work, in addition to timely and truthfully report to their superiors, but also to make a record, learning, review, to ensure zero-error process can be done in accordance with a more standard process in the next maintenance work preferred state. In short, boiler maintenance and repair will directly affect the life of the boiler, the use of safety, efficiency, and normal operation of the equipment and so on, so be sure to regulate the operation.
Work environment condensing boilers are generally more severe, partially condensing boilers using spaces not only have serious moisture, there are still many chemically aggressive media, combined with condensing boilers daily work of a higher frequency, so on its weather resistance and environmental resistance put forward higher requirements. Professional condensing boilers in the design and production process to effectively circumvent the late failure frequency, so that the failure rate lower condensing boiler, longer life.
