Industrial Gas 5 Ton Steam Boiler

Recently, the letters and the ecological environment unit, the letter of "boiler air pollutant emission standards" in the "gas boiler exhaust pipe predetermined height of not less than 8 meters, within 200 meters from the building around the radius of the new boiler room chimney when was the tallest building in which the chimney should be higher than 3 meters "requirement questions.

First, the new urban gas boiler chimney should be performed outside the specified height is 3 meters above the surrounding buildings (there are many communities within 200 meters around the building height higher)?

Second, on the 20t / h steam boiler and above, and more than 14MW hot water boiler to be installed pollution-line monitoring equipment, this means that a single 14MW boiler or boiler means the total audience of 14MW?

Third, for example, I have more than 2MW heating station natural gas hot water boiler 7 units, exhaust gas through the two exhaust pipe emissions, the need to install pollution monitoring equipment?

A "boiler air pollutant emission standards" (GB13271-2014) states that "fuel, gas boiler stack height of not less than 8 m, particularly boiler stack height is determined by the EIA document approved. Chimney around the new boiler room when there is a building within a radius of 200 meters, the tallest building in which the chimney should be higher than 3 meters. when there is a building within 200 meters around the new boiler house chimney radius, "according to the provisions in the new urban area gas boiler should be implemented", the chimney should be higher than the provisions of the tallest buildings in more than 3 meters, "the.

Two, 20t / h steam boiler and above, 14MW and more hot water boiler must be installed in the line monitoring apparatus contaminants "14MW and more hot water boiler" means a single boiler.

Third, on the "exhaust gas through the two exhaust pipe emissions, the need to install pollution monitoring equipment" problem, according to "People's Republic of China Air Pollution Prevention Law" Article 24 "key sewage units should be installed, using air pollutant emissions automatic monitoring equipment, and environmental protection departments to monitor network devices, monitoring equipment to ensure the normal operation of public and emissions information in accordance with law. "provisions, as well as the" State Council on the issuance of three-year action plan to win the blue sky to defend the notice "(Guo Fa [2018 ] No. 22) "outfall height of over 45 meters of elevated source, as well as petrochemicals, chemicals, packaging, printing, painting and other VOCs emissions from industrial sources focus, the focus of sewage into the Directory of key areas should be basically completed by the end of 2019 to install flue gas automatic monitoring facilities, the country should be basically completed by the end of 2020 the automatic installation of flue gas monitoring facilities. "requirements, if the exhaust pipe where the company was listed as key units of sewage, flue gas monitoring facilities should be installed automatically, otherwise, no installation.

Gas boiler szs 1 emergency shutdown procedures, if necessary emergency shutdown generally, when the boiler encounters one of the following, operation should be stopped in case of emergency; (1) allow the boiler steam pressure exceeds a safe pressure, fueling is stopped strengthen water supply, measures the wind pressure continues to rise. (2) boiler severe water shortages. Water meter can not see the water level. After being called water, the water level of sight. (3) When the severe water boilers, boiler water level is higher than the highest water level is visible, but the emission level not yet seen. (4) increase in boiler water, take other measures, the water level will continue to decline. (5) water supply device is turned off, standby equipment. (6) all water level gauge or invalid. (7) All the safety valve all the failures. (8) All all-off failure drain valve. (9) causing damage to the boiler pressure element (e.g., boiler tubes, etc.), or endanger the safety of the device. (10) boiler is a serious threat to other events and safety equipment. 2, natural gas boiler operation method szs immediate emergency stop operation of the controller, the boiler is off, closing the front of the boiler gas valve to stop the gas supply. The industrial 5 ton steam boiler competent completely separated, opening the exhaust air valve or safety valve steam pressure. Due to lack of water, the boiler is not allowed into the boiler, the steam is not discharged to reduce pressure. No shortage of water, cold water can drain down alternate method, the water level remains complete accident should immediately stop the water supply, water reducing combustion (fire artificially changed into a small fire), play an open valve while opening the main steam pipe and the drain valve cylinder to prevent the steam to carry large amounts of water, water. In the shutdown process, the cooling rate of the furnace should not be too fast to avoid flue compression member and the expander is damaged suddenly cooled. 3, emergency shutdown processing method szs natural gas boiler in the case of emergency shutdown, due to the nature of the accident, the following may take a different approach: (1) rapid flame treatment emergency shutdown, the burner first station, and closing the valve flame gas supply is stopped after the cut valve, to maintain the water level is normal. (2) rapidly cooling the furnace or water if there is no water leakage during an emergency stop, the cooling time can be shortened to the boiler water and sanitation and reduce the pressure. When the boiler water temperature down to 80 degrees Celsius, boiler water can be discharged. If the boiler severe water shortages, the boiler can not cool quickly in the event of an outage. Non-water to the furnace, or explode. accident. (B) natural gas boiler shutdown SZS normal shutdown (complete shutdown, shutdown maintenance) procedures which can be used when needed repair or stop steam boiler. 1. If one of these faults, the leaders agreed, the boiler can be temporarily closed repair: bilge faucets, riveted joints leak, damaged tubes, the waterwall tubes, the heating tube, the flue gas contacts the drum, the head, off pipe insulation, water supply system, combustion system, a serious fail-safe accessories, in need of repair. 2, a temporary repair (or normal shutdown) the method of operation in order to stop the burner, for closing the valve. Boiler feed water to 2cm above the normal water level, to stop water supply, reduce the pressure. 3. Turn the main steam valve, open the traps, and steam boiler operation, reliable water separator. 4, boiler feed water close electric valve and manual valve, boiler feedwater reliable cutting. When the steam pressure drops to zero, the water can be supplied and discharged alternately, so that water is gradually cooled furnace, when the temperature drops to 50 degrees Celsius (or hand potshell touch feeling hot pan head), can be completely discharging furnace boiler water water . Before water, open the air valve on the boiler or lift safety valve. At this point, you can enter the furnace for inspection and repair. Cooling the furnace must be kept slow, non-violent cooling and damage to the boiler, the boiler can be stopped from the repair into the furnace, the cooling time is generally less than 24 hours. Close the furnace over 24 hours, shut off the gas supply valve at the regulator, and open the gas conduit pipe is responsible, in the exhaust gas pipeline.

Oil-fired boiler safety instructions oil-fired boiler is one of many hot water boiler to one of how to prevent boiler fuel boiler appears to be abnormal use it? First, to ensure the normal operation of the fuel in the boiler feed water quality and quality of qualified soda, to reduce the water wall tube fouling and corrosion, strengthen supervision and boiler water boiler water when found unqualified, should increase the number of times a given row; while the flue gas flow rate control , especially when the flue gas velocity in the corridor, during installation and servicing, should minimize the distance between the wall and the superheater tubes, while the distance between the tubes to uniformly as possible. second, the fuel boost heating boiler carried out in strict accordance with procedures, control the speed boost. were lower header sewage water wall work required to build the water cycle as soon as possible, promptly switched the gun to ensure uniform heating surface is heated to eliminate half of combustion, eliminating thermal excursions. third, do a good job adjusting fuel combustion boiler, the flame deflection preventing, controlling coal fineness noted that, with a reasonable air to prevent coking, reduces thermal excursions, to prevent the tail reburning fuel boiler; boiler steam parameters be closely monitored, and the main indicators of the amount of water evaporation and the like, to prevent pressure Release, full of water, water accident. fourth, strengthening sootblower sootblower and management, serious fouling preventing heating surface, when there is found furnace coking phenomenon, should be increased blowing Gray times, ensuring good water wall heat sink; overheating problem of the presence of long-term heating surface, installation of thermal supervision controlling temperature measuring points; expansion to ensure accurate indication means using oil-fired boiler units must be fully taken into account the safety problems. in the inspection process must be meticulous in place. to ensure the personal safety of the unit.
