Wenzhou City, Zhejiang Province, is one of the countries and determined implementation of the regional focus of the Battle of Blue Sky. In order to improve air quality in the city of Wenzhou, improve people's livelihood well-being, for the governance of air pollution, Wenzhou City, developed and introduced the "winning Blue Sky Battle action plan" (hereinafter referred to as "embodiment"), give the city the power to defend "Wenzhou blue." Program 2020, in Wenzhou PM2.5 average concentration is maintained at 35 micrograms / cubic meter (city maintained at 31 micrograms / cubic meter), air quality control over the ratio of the number of days of 90% (93% city control ), severe weather and pollution more effectively controlled.

"Plan" also lists the specific implementation timetable: by 2020, the basic completion of provincial trunk pipeline construction, the basic realization of natural gas every county, the city's natural gas consumption amounted to 570 million cubic meters. In principle, to new natural gas cogeneration and gas chemical projects. By 2020, the city's total coal consumption decreased by 5% compared with 2015, accounting for the proportion of total energy consumption fell to 42.8% or less.

There are several types of "big coal" will be gradually phased out, including environmental protection, energy, security and other non-compliance of 300,000 kilowatts coal-fired units, 10 steam tons / hour and tea furnace coal-fired boilers, around the built-up area , operating a stove, grain storage and drying equipment, coal-fired facilities, more than 10 steam tons / hour and 35 steam tons / hour of coal-fired boilers. Before the end of 2020, 300,000 kilowatts and above thermoelectric coal-fired boilers and small coal-fired thermoelectric backward within the range of 15 km radius of the heating and power plants all closed down integration.

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 vertical fired 750kg steam boiler dealer price 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.

20 ton oil gas vertical fired 750kg steam boiler dealer price in a pharmaceutical factory

As we mentioned earlier, steam boilers are of great significance in pharmaceutical companies. We have supplied a 20-ton oil gas steam boiler to a pharmaceutical company overseas. In this pharmaceutical company, steam boilers provide heat for the disinfection of raw materials, sterilization of utensils, and drying of tannins. Our technicians provide customers with a 20 ton wns series oil gas steam boiler based on the information given by the customer.

Coal fired watertube boiler is a type of coal fired boiler in which water circulates in tubes heated externally by the fire. Coal fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. ZG Boiler manufactures coal fired firetube boiler and watertube boiler for sales. In Aug 2014, our company exported a set of 15 ton SZL coal fired firetube boiler to Thailand, an paper factory.
