National Day holiday just ended, Shenyang Environmental Protection Bureau threw himself into the urban environment construction. Before the onset of winter, the Shenyang municipal government will strictly control the air pollution problem. It is reported that Shenyang Environmental Protection Bureau issued out since November 1, Shenyang will strictly enforce the standards of air pollutants emission limits in particular, all the environmental standards of heating enterprises will be cleared out of the heating market.
Shenyang Environmental Protection Bureau issued "on the thermal power industry, coal-fired boilers execution of air pollutants in particular emission limits of the notice" in the next year (the "Notice") requires: Thermal power within the gamut of Shenyang, iron and steel, petrochemical industry and fuel emissions of air pollutants in coal boiler project "thirteen five" period should implement special emission limit standards.
Shenyang is also a good environmental citizen blue sky, Shenyang City this winter and will continue to adhere to "turn point furnace, load shifting blocked arteries," the implementation of standards. After heating units gradually open blocked arteries, Municipal Environmental Protection Bureau will strengthen the routine inspection of law enforcement, and pay close attention to on-line monitoring data 474 coal-fired boilers, boiler emissions of non-compliance immediately ordered to carry out rectification, and severely dealt with strictly waste-water treatment, ultra row of such acts. At the same time, the Shenyang municipal government will also heating units regularly conduct random sampling of coal quality.
It is understood, Shenyang open blocked arteries in succession since October 26 from heating. To ensure that excessive heat stable and safe operation standards, Shenyang will be fully commissioning of heating facilities, to solve problems in a timely manner to ensure the November 1 time blocked arteries heating, the temperature reaches above 18 ℃. After the blocked arteries, Shenyang will strictly implement the winter heating emergency plans to complete the repair within 6 hours general accident, complete repairs within 24 hours more accidents.
Shenyang Environmental Protection Bureau official says, the environmental protection department will be heating business day on-line monitoring, and strictly control their emissions of air pollutants. Over the years, Shenyang has been doing the heating business "remove small and large," the relevant measures, so that some can not afford to increase environmental protection facilities of small companies to large companies merge powerful, let Shenyang municipal heating more environmentally friendly. Strict implementation of the special emission limits of air pollutants standards, both national policy, but also the heating of corporate responsibility, companies must increase investment in environmental protection to ensure the discharge standards.
It is understood that this year, the Shenyang municipal heating will continue to increase the proportion of clean energy, clean coal existing store 230,000 tons, an increase of 30,000 tons last year. Shenyang City, natural gas and other clean energy heating an area of 150 million square meters, clean heating the proportion reached 45%, up 6% over last year. Reduction of 1 million tons of total coal year, 5000 tons of coal-fired boilers to complete denitrification, the city starting from November 1 particularly strict implementation of air pollutants emission limits.
Gas condensation boilers for cooking system has hierarchical modules start function, the system according to the level of the set temperature, the automatic adjustment module start / stop working. At the same time, the control system automatically balances each group working time of the module, to extend the service life of the overall system.
Boilers are classified also by their pressure capacity, design type and use. Maximum allowable working pressure, or MAWP, is the highest amount of pressure that the boilers for cooking is designed to withstand. This pressure is measured in terms of pounds per square inch or “psi,” and gauge pressure is expressed as “psig.”
Because gas-fired boiler is a kind of container equipment with steam and pressure, it is easy to cause accidents if the safety code is not followed in the course of operation, so, Gas-fired boiler operators must follow the rules and regulations to implement the relevant procedures and make good operation and shift records. The following is a high-stability gas-fired boiler manufacturers to introduce what checks should be done before the start of the furnace.
1. When checking the appearance and gas pressure of the boiler, when preparing to start the gas-fired boiler, the on-duty furnace worker should first do a comprehensive inspection, including the appearance of the boiler, the valves and the connecting parts, and then check the pressure of the gas. Ensure that the pressure value is within the normal range, not too high or too low, and that the gas supply valve cannot be opened until it is checked and confirmed to be normal.
2, check the water supply system gas-fired boiler when burning, there should be water inside, otherwise there will be danger. Therefore, before the stove is opened, the boiler workers should check the water supply system and see if the pump can supply water. If the water supply is not properly switched on, the exhaust valve should be opened and ventilated, knowing that the pump can start the water supply. Then open the valves in the water supply system.
3. Checking the water level if too much or too little water in the gas-fired boiler will have an impact on the safe operation of the boiler, it is very important to check the water level gauge well before the start of the furnace. Because the function of the water level gauge is to let the stoves know how much water there is in the boiler at the moment. Therefore, before starting a gas-fired boiler, it is necessary to see whether the position of the water level gauge is normal or not, and also to see whether the level gauge and color plug of the water level meter are in the open position, so as to avoid the phenomenon of false water level, and then to observe whether there is a shortage of water. If lack of water can manually carry out boiler water filling.
