1 25mpa horizontal gas boiler China steam boiler for industrial use high quality

Steam boiler is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that 1 25mpa horizontal boiler china steam boiler for industrial use high qualitys works at low to medium pressure. Compared to oil and coal fossil fuels, gas is a cheaper and more environmentally friendly energy. With the development of the economy, people begin to seek for a new lifestyle and they have a higher requirement to the environment, therefore, gas as a cheaper and cleaner energy is more and more popular around the world. Gas fired steam boiler also becomes a good choice for power generation.

At the completion of the city's foundation 10 steam tons / hour and the coal-fired boiler Chaigai, and gradually expand the coal-fired boiler demolition and clean energy transformation range, before the end of 2020, the city planning area basically eliminated 35 tons of steam / coal-fired and boiler.

Xinyang, Henan decreasing year by year funding award boiler fill ways:

(1) the completion of the coal-fired boiler Chaigai before the end of October 2018, giving not less than 60,000 yuan / tons of steam financial awards complement;

(2) the completion of the coal-fired boiler Chaigai before the end of October 2019, giving not less than 40,000 yuan / tons of steam financial awards complement;

(3) complete Chaigai coal-fired boilers for the end of October 2020, the prize money will not give up.

At present, many City in Henan Province have been put forward relevant atmospheric Prevention Act, because the policy has landed Henan Province, allowances and Chaigai range of boiler Metro Toronto are the same.

The reason you need to know the boiler energy consumption (reheat steam temperature) reheat steam temperature problems 1. Circumstances reheat temperature rises 1.1 Move boiler furnace flame center, furnace outlet temperature increases (see main economic indicators No. 5 boiler exhaust gas temperature). 1.2 coal increased too fast. 1.3 Excess air amount is increased. 1.4 pulverizing system start-stop. 1.5 Automatic control of the reheater desuperheating water improper adjustment. 1.6 reheater sootblowing time poor choice. 1.7 feed water temperature is low. 1.8 the high pressure turbine exhaust temperature is high. Next to the 1.9 high leakage, high reheater inlet temperature. Hot and cold extraction section greater then 1.10. 1.11 boiler heating surface design is unreasonable, over-temperature reheater tube wall, forced cooling operation. 2. Reheat the following partial flame temperature is lowered center 2.1: burner tilt deviation, hem; burner is switched from the upper to the lower layer, the lower layer or to an excessive amount of the powder; volatile coal fraction is increased, the pulverized coal thinning, water reduction. 2.2 reheater heating surface fouling, slagging, fouling the interior. 2.3 Save reheat the heated drain valve. 2.4 automatic adjustment inappropriate, excessive reheater desuperheating water. 2.5 feedwater temperature. 2.6 economizer and water wall sootblowing time poor choice. 2.7 reduce the amount of coal too fast. 2.8 # 1, # 2 high pressure heater is disabled, increasing the reheated steam flow.

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 1 25mpa horizontal boiler china steam boiler for industrial use high quality 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.
