Energy-Saving 1 MW Hot Water Boiler for Central Heating

Priming steam boiler accident 1 boiler priming phenomenon ⑴ water level in the water table up and down sharp fluctuations in the water line blurred. ⑵ pot of water alkalinity, salinity seriously overweight. ⑶ steam with a large amount of water, decreased steam quality, superheater outlet steam temperature drops. ⑷ water hammer occurs in the steam boiler tubes, steam leakage occurs at the flange connections for leaks. 2, the boiler Priming process ⑴ weakened burning off a small main steam valve, to reduce the evaporation boiler, to reduce the load and remain stable. ⑵ fully open the drain valve on the surface of the drum (continuous blowdown valve) and a lower discharge drum appropriately. At the same time to increase the amount of water to reduce boiler water alkalinity and salinity, and you should pay attention to control the water level of protection. ⑶ using boiler pot-treatment, dosing should be stopped. ⑷ open the superheater, the steam trap and a sub-cylinder pipe. ⑸ maintain boiler water level slightly lower than the normal level. ⑹ notice water treatment personnel to take measures to ensure the supply of qualified demineralized water. Increasing the pot of water sample testing times, until the pot of water before qualified becomes normal operation. Before ⑺ boiler water is not improved, increasing boiler load is prohibited. After the accident elimination, should be promptly wash water gauge.

How to maintain the use of gas energy-saving 1 mw hot water boiler for central heating? Note the use of gas-fired boiler: brief, the boiler equipment to gas as the main fuel is called the gas boiler. About gas boiler users, be sure to do routine maintenance work equipment, so it can ensure normal operation. 1, carefully check before ignition if the water in the boiler and fill the system, the exhaust whether intelligible. 2, gas pipeline stuff leak check, whether the gas pressure matching with the original. 3, gas boilers must use the original power plug, gas boilers must be firmly grounded, to ensure safety. 4, gas boilers must pay attention to ventilation in the process of applying. 5, the installation and repair of gas boilers must end by professionals. 6, presents problems should be closed first gas source and the power control instructions discharge fault, fault and restart the discharge. 7, when possible icing environmental conditions, adhere to energize the gas boiler and ventilation, to ensure that the antifreeze and anti-death function card gas boiler work. 8, if a long time without gas boiler, please close the air supply cut off the power, where possible icing of the environment, must be the boiler and piping the water to shoot clean to prevent freezing. Followed by screening of coal-fired boilers, gas hot water boiler is now the most mainstream of steam boilers and hot water boilers. To do the normal operation of the boiler, we should take good care of the boiler. Here are some common maintenance methods. (A) so that heat hot water boiler maintenance has always insisted on a pressure of about 0.05-0.1Mpa to avoid outside air into the boiler, oxygen-free environment and the water temperature is not lower than 100oC. If there are other possible additional boiler boiler steam heating bath water. If a single boiler, can adhere to set fire in the furnace. This method is generally used in less than one week shutdown boiler or boiler hot spare. (B) Wet Wet maintenance boiler maintenance alkaline solution to the surface of the base protective film to avoid corrosion of metals. After the boiler shutdown, first pot of water exhausted, soot scale clean-up, closed the other into the hole, and other barrier boiler is in operation. The water is injected to the minimum level, then the alkaline solution was poured configured. Component preservation solution are: sodium hydroxide, the ratio of 5kg / t. After all filled with demineralized water injection boiler. Now open the dedicated circulation pumps, uniformly mixed alkaline solution. During maintenance to regularly check if the increase in time to reduce the concentration of the solution; cold weather to avoid freezing water boiler, the boiler can not open wet maintenance. Maintenance end, all water should be released and re-install water softening. (C) Dry Dry maintenance care stick inside the boiler from corrosion sulfate, anhydrous calcium chloride or lime used. After the shutdown is done and the pot of water, cleaning boilers, boiler pipe valve closed. Open pores make the drum to dry naturally, if the water vapor may be heated by more slow fire. The anhydrous calcium chloride or lime with a tray placed on the hob, and an inner drum and headers flue. Based on the amount of boiler concluded in accordance with the size of the boiler. All valves eventually closed and isolated, to avoid moisture ingress. During maintenance, every 2 months, a timing check, if the desiccant into powder, should be replaced with new. Practice has proved that dry maintenance effect is obvious and low cost, simple operation, suitable for all types of boiler maintenance shutdown a long time, especially in summer to disable heating and hot water boiler.

Dongying City, Shandong Province in response to low-nitrogen coal-fired boilers, industrial waste heat recycling and other environmental policies, combined with local conditions, Dali urban and rural areas to promote clean heating projects, and achieved remarkable results. As of mid-October this year, Dongying City clean heating rate of more than 72%.

Recently, Dongying Municipal Urban Management Bureau to the outside world, in order to further promote the urban and rural clean heating, it has already shut down 10 coal-fired boilers environmental non-compliance of a total of 155MW.

After shutting down 10 coal-fired boilers environmental non-compliance, Dongying City high environmental standards were established in a total of four 58MW gas-fired boiler and a total of four 70MW coal-water slurry boiler through a series of energy-saving treatment, flue gas emissions much higher than the index of new environmentally friendly ultra-low emission requirements.

Meanwhile, Dongying City, the original heating effect is also unsatisfactory 4.33 million square meters of heating regions to establish a uniform heating systems, and the use of standards to ensure clean heat source; higher operating costs for the original 2.17 million square meters of heating area heat source replacement process, both to ensure good heating effect but also saves a lot of money.

According to statistics, this year the city of Dongying city plans to add a total area of ​​clean warm 8.1138 million square meters, down to the next new clean heating in rural areas 45000.

Recently, Dongying City issued a "Dongying City 2018-- 2020 coal consumption reduction alternative work" (the "Program"), after the completion of the city's 10 steam tons / hour and small coal-fired boilers zero and start steaming for 35 out of work t / h coal-fired boilers and, as of 2020, out of 35 steam tons / hour and coal-fired boilers.
