horizontal hot water boiler startup procedure
Inner Mongolia Autonomous Region Development and Reform Commission issued a notice publicity Inner Mongolia clean heating in winter embodiment (hereinafter referred to as "Notice"), "notice" mentioned that in 2019 the region to achieve clean heating rate of 50% in 2021 to reach 705; urban built New forbidden zone 35 tons of steam / hour and below the coal-fired boilers, which Hohhot, Baotou, Wuhai city urban area will phase out 35 tons of steam / hour and below the coal-fired boilers, all new buildings to achieve clean heating.
The region's total heating area of about one billion square meters of urban heating an area of about 750 million square meters, of which: decentralized heating an area of about 090 million square meters; central heating an area of about 660 million square meters, heating rural area of about 250 million square meters, of which central heating an area of about 027 million square meters, the rest are dispersed heating.
Urban areas mainly in the CHP and district heating central heating boiler room mainly to gas, industrial waste heat, wind power, solar and other energy sources to supplement heating. Rural areas with decentralized heating the main heating source mainly scattered coal-fired boilers, conventional coal-fired furnace or straw.
Urban district heating cogeneration accounted for 51.5%, the proportion of area of 43.6% heating boiler, gas heating accounted for 4.5%, the proportion of the heat pump in other ways, electric heating and the like about 0.4%.
To clean as the goal, in ensuring the safety of people's livelihood heating premise, overall thermodynamic equilibrium between supply and demand, either alone or using a combination of various cleaning heating mode, alternative urban area and would like to keep burning coal for heating casual, less warm air pollutants areas emission. Adhere to safety bottom line, build a reasonable size, safety and reliability of heat supply systems.
2, according to local conditions, the residents can afford. Based on natural resources, economic strength, infrastructure around such as regulation and install air pollution control requirements, scientific assessment, depending on the region to its own characteristics, full old people's consumption capacity, adhere to both energy security and clean development, should power the electricity, should be coal is coal, the gas should be air, clean heating strategy adopted XI, to promote its low cost and low pollutant emission cleaning combination heating under the same conditions.
Considering the urgency of the air pollution control, affordability, work to promote the difficulty and other factors, co-ordinate the work of promoting cleaner heating city, county and urban-rural.
Guidebooks steam boiler steam boilers since more and more frequent, more and more widely, boiler spate of incidents are not uncommon, in the final analysis neglect of usual maintenance boilers, today to talk about Guidebooks steam boiler. 1, before starting to check whether the inlet valve is opened to prevent damage to the machine and the dry interior. The dry steam boiler is strictly prohibited. 2, after completion of production to be shut down from work, and to discharge all the water inside the furnace, the machine to prevent furring. 3, after the completion of the sewage recommended to open all valves, turn off the power. 4, recommended weekly cleaning the furnace and supporting the soft water treatment equipment, each cleaning time is about 1 small. 5, regular inspection line, aging electrical wiring and replacement. 6, regularly turn on the heating furnace tube completely cleaned up once the scale. 7, each year the boiler inspection (Inspection and sent to the local boiler), safety valve, pressure gauge must be verified. (Henan Fang fast production of steam boilers are atmospheric type, so do not send the annual inspection)
Test operation steps of gas-fired steam boiler
Gas-fired steam boiler trial operation is an important part of comprehensively testing the quality of the design, manufacture, installation, commissioning and production preparation of the main engine and its supporting equipment. It is an important procedure to ensure the safe, reliable and economic operation of the boiler in the future.
Extend the life of the boiler shutdown maintenance (auxiliary boiler) after the end of the heating period, the heating boiler has shutdown of more than six months a year, stop running such a long period in the boiler, if the units do not pay attention to maintenance of the boiler, establish and improve various rules and regulations do not or do not take proper care measures, it can easily cause corrosion in the boiler, the life of the boiler and therefore will reduce the economic efficiency of enterprises will also be seriously affected. So strengthen the maintenance work during the shutdown of the boiler, it is of great significance. 1. Grate: Grate pad wear Check the boiler fouling cleared up the middle slot, if necessary, replace the grate. Grate front axle oil level check, timely lubrication. Check whether the switch lever grate Flexible damper sides. Start fan running for 20 minutes, to grate fouling purge. 2. reducer: the oil discharge portion open vent hole, where the oil quality was observed. The need to replace all the oil inside the gear if necessary. 3. blowers: Open inspection hole fan, check the fan wear, if worn on the need to re-adjust the fan balancing. Fouling bottom clean-up fan housing. Check the oil level air quality timely replacement of oil, add oil. Pairs of primers were cleaning the bottom of the blower housing. 4. Cleaner: to take over the slag discharging ditch water submersible pump, a chain wear Cleaner inspection, replacement of the flap chain if necessary. Check the Cleaner head bearing box oil level, add oil in a timely manner. 5. Dust: Internal precipitator for dedusting treatment. 6. Air Compressor: Check compressor oil, timely oiling. After the dust clean-up is complete, turn on the air compressor to purge the filter to work. 7. Chimney: open the bottom of the chimney, cleanup internal fouling. 8. decontamination: the decontamination out of the water valve closed, open decontamination hand hole, decontamination of sludge within the debris clean up, clean-up after the completion of the closed hand hole, out of the water valve and open the drain valve decontamination for decontamination flushing. After draining off water until the drain valve. 9. Valve: pump room and boiler room on the check valve, leaks, opening and closing is flexible tight.
