manometer tekanan boiler 40 kg
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.
How to convert between the three expressions of hot water manometer tekanan boiler 40 kg output?
There are three common expressions for the output of hot water boilers, namely Kcal/h, t/h, and MW. So what do they mean, and what is the conversion relationship between them?
Teach you how to deal with gas leak:? The main purpose of the manometer tekanan boiler 40 kg is used in the civilian heating, and now the state has in the promotion of energy saving and environmental protection, pollution problems in the past of coal-fired boilers is indeed serious, is now gradually developed gas-fired boiler, If a natural gas leak gas boiler used encountered fire, static electricity, lightning or improper operation such as an explosion, a fire in a confined space will make people hypoxia, asphyxia and even death, and to the production safety of life and property caused immeasurable loss. Today, fast boiler manufacturers take you look at it. 1, indoor gas pipeline leak: immediate emergency shutdown, cut off the boiler room of the total valve, notify the gas company to company safety and production department report, leaks of natural gas is processed in accordance with the emergency plan. 2, gas boiler leaks. (1) emergency shutdown (pressing the emergency stop button). (2) to close the mesa gas boiler gas valve, cut off the gas source. (3) for processing a natural gas leak emergency plan. 3, the burner leaks: immediate emergency shutdown, cut off the main valve of the boiler and to report on corporate security department and production, natural gas leak processed according to the emergency plan, organize technical maintenance personnel. 4, the control, regulation, measurement and components leaking joints. Immediate emergency shutdown, cut off the main valve of the gas boiler station and report back to corporate security department and production, natural gas leak processed according to the emergency plan, organize technical personnel replace the control, regulation and measurement components, leakage of its position resealing the joints.
It can increase the application range of heat transfer unit equipment and the design scope of heat transfer operation in process design, which has the advantages of rapid cooling and heat transfer capability and smaller temperature difference between heat transfer and heat transfer, which can increase the application range of heat transfer unit equipment and the design scope of heat transfer operation. It also provides possibility for some previous designs which are limited by heat transfer rate or temperature difference, such as recovery of heat energy by small temperature difference, small temperature difference cooling, rapid and accurate constant temperature control and so on. This is due to the fact that plate heat exchangers are also thin-layer heat exchangers. The thermal deviation of each parallel heat pipe group should be reduced as far as possible, for which the return water of the system entering the manometer tekanan boiler 40 kg should be adjusted and distributed. For ordinary low-temperature hot water boilers, the hot water flow rate is large, can The natural distribution, that is, the amount of water entering each parallel pipe group, is allocated naturally according to the heat condition of each pipe group and the size of pipe resistance. Although the structure of natural distribution is simple, but the safety and reliability of boiler operation is poor, for high temperature hot water boiler, the relative water quantity is less, so it is not suitable to adopt natural distribution mode, but the valve should be used to adjust the distribution, according to the size of heat load of heating pipe group, Supply the corresponding circulating water to ensure that the outlet water temperature of each parallel loop does not vary greatly. At this point, the outlet water temperature deviation of each loop can be controlled within 10 degrees Celsius. The heat pipe of the retrofitted hot water boiler must be kept to a certain extent. Water flow rate to ensure heat pipe cooling, prevent oxygen corrosion and the deposition of impurities in the water. The downlink heat pipe should also maintain sufficient water speed. After modification, the stagnant zone of water in the boiler should be reduced as far as possible, especially at the end of the drum. Otherwise, oxygen corrosion can be easily caused. In order to remove the gas from the water in time, the exhaust valve should be set at the highest point of each loop of the boiler. When refitted into forced circulation hot water boiler, measures should be provided to prevent sudden power outage and kettle vaporization when pump is stopped.
