To better implement the spirit of the CPC Central Committee nineteen Japanese National Assembly ecological and environmental protection, and resolutely respond Blue Sky Battle action, August 27, Qiqihar, Heilongjiang Province, the city government announced the "small coal-fired a515 gr70 boiler steel plates Qiqihar City 2018-2020 to promote the phase-out plan" (the "program"), a more concrete of small coal-fired boilers on the basis of governance "Qiqihar City, 2018-2020 tough fight pollution prevention action plan" on.
"Plan" to improve air quality at the core, to take the most effective measures for key areas of work, the various departments collaborate together to complete the task of eliminating small coal-fired boilers.
"Plan" work plan is divided into three phases:
1, before the end of September 2018, in addition to the boiler must be retained, built-up areas in the central city and the rest of the county (city) to complete a full range of 10 steam tons / hour and coal-fired boiler or elimination process.
2, before the end of 2019, each county (city) out of more than 50% of the 10 steam tons / hour and coal-fired boilers.
3, before the end of 2020, in addition to the boiler must be retained, built-up areas outside the central city and the rest of the county (city) the scope eliminate or convert 10 tons of steam / hour and coal-fired boilers.
School education as an important place to nurture talent, in order to provide a good living for masters and school environment, gas a515 gr70 boiler steel plates low pollutant emissions clean environment is an excellent choice.
How to maintain the use of gas hot water a515 gr70 boiler steel plate? 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.
