CWNS Series Oil Industrial Hot Water Boilers
1, Safety Precautions: 1 gas cwns series industrial hot water boilers room should comply with fire safety requirements, and equipped with the necessary fire-fighting equipment. Storage of flammable materials, such as oil, wood and the like. Non-smoking room, non-smoking room, non-idle personnel and miscellaneous personnel. 2. The operator should be familiar with the structure and performance of hot water boiler components, specifically the installation location and function of the main components, prohibit untrained personnel into the boiler room operation device. 3. A gas water heater enters the room the operator must carry combustible gas, before closing and power, gas chamber must be checked to ensure that the concentration of the gas chamber is not higher than 0.5%, is prohibited switch off transmission. At the same time, we must take effective measures (open windows and doors) for ventilation. 4. Before starting, the supply voltage must check meet the requirements, no phase ground fault or damage, electrical control equipment and mechanical devices meet standard requirements, trouble-free start. 5. Before you start circulating pump must ensure that the system of heat and hot water valve intact, hoist flexible, good pressure gauges, thermometers and other facilities, piping systems leak, the water supply tank water level to the required standard. Otherwise forbidden to open the device. 6. Before starting, you must check the gas supply system to ensure no leakage, pressure is normal, compliance (> 8KPa). If the air pressure is abnormal, the ban starts.
Two of the three types of protection devices What is the difference of fuel vapor steam boilers and boiler fuel gas steam boiler steam boiler fuel for steam boilers, steam boilers or fuel oil-fired boiler is in, no matter which argument, are refers to this kind of boiler fuel steam boiler. 1. the type of fuel steam boiler fuel steam boiler, which in general, can be divided into both established and horizontal. Vertical fuel steam boiler: the combustion engine, generally use the set in this manner, and using two-pass configuration, so that complete combustion can be performed. In addition, the use of these forms, the stability of the operation of the boiler, it is also very beneficial. The advantages of vertical steam boiler fuel, mainly for high thermal efficiency, and can reduce costs. Horizontal fuel steam boiler: the structure, using a three-pass tube pyrotechnic this configuration, pressurized combustion chamber so that combustion, thereby reducing the combustion load, and reduce exhaust gas temperature. As a result, promote energy conservation, economic performance of the boiler. Further, since the waveform of threaded pipe and furnace thermal efficiency of the boiler can be remarkably improved, and the use of time can be increased. 2. The fuel vapor pressure protection boiler controller: generally this type of high sensitivity, is mainly Zidongkongzhi or chain protection. And may be adjusted according to actual operating pressure of the boiler, so that appropriate. Flame protection: in the main burner, a flame failure protection devices. Its role is the amount of fuel steam boiler combustion is detected, when abnormal combustion, can take immediate steps to make the boiler stopped working in order to avoid some of the adverse consequences. Self-locking power failure protection: Usually burst power for this case the use of the protective device, so that when a sudden power failure, the fuel steam boilers can immediately shutdown and self-locking. Note, however, that when power is restored, the boiler will not start on its own, it must be reset after unlock, boiler to start the ignition and start working. Fuel gas steam boiler and the steam boiler distinction fuel gas steam boiler and a steam boiler, as energy saving device belong to the combustion products of carbon dioxide and water, will not pollute the environment. Oil-fired boiler and gas boiler biggest difference is the use of different fuels, gas boilers use natural gas, city gas as the fuel, light oil, heavy oil-fired boiler is used as fuel. In contrast gas boilers, boiler fuel cost is much higher than gas boilers, therefore, those commonly used in the oil-fired boiler operating conditions of enterprises do not have a gas boiler or Shiyedanwei use. The difference between the fuel and gas steam boiler steam boiler: 1, fuel different: the former light oil, heavy oil as a fuel, which uses natural gas, city gas, liquefied petroleum gas as fuel. 2, the burner different: the former use of oil burners, gas burners later use. 3, different cost: the former high cost, about 1-2 times the cost of the latter. The same point of the fuel gas steam boiler and a steam boiler: 1, the same boiler: the same tonnage same steam boiler or cwns series industrial hot water boilers of the boiler body. 2, the same auxiliary components: in addition to the burner, auxiliary oil-fired boiler and gas boiler accessories equivalent tonnage same. 3, the same production process: The process of production and processing were carried out in accordance with the same process and production standards.
Here's how to conserve water pump.
1, gas boiler feedwater pump failure prevention routine maintenance must be for the purpose of curing system and establish a scientific system to guide routine maintenance work to the pump.
2, the establishment of feed pump failure and replacement parts records, detailed grasp the parts damaged time so late in the component to be replaced before the life, avoid parts (such as: bearings, etc.) that is not timely after damage caused by damage to the unit .
3 occur, to strengthen the maintenance and regular checks amount of lubricating oil pump lubrication system, lubricating components in a timely manner, to avoid "dry grinding" and other conditions.
4, prior to the addition of the lubricating oil to be attention to check the quality and cleanliness of the oil addition port, to avoid the process of adding impurities into the bearing damage. Also note that in the conservation of the inspection and maintenance of the system piping to the pump, in a timely manner at plugging leaks, rust-proof coating the outside of the pipeline should always be checked for spray coating peeling off promptly at, in order to ensure that the tube corrosion path. Maintenance also need to pay attention to the inspection and maintenance of pump water treatment system.
Battle for winning Blue Sky, effectively improve the region's ambient air quality; Ningxia Hui Autonomous Region developed and published a "region-owned coal-fired thermal power units reconstruction plan for the ultra-low emission" (hereinafter referred to as the "Program"). "Plan" put forward plans before the end of 2020, nine companies owned coal-fired power plant 25 thermal power units for ultra low emissions transformation.
By the end of 2020, all the region's coal-fired thermal power units with self-transformation conditions by upgrading desulfurization, denitrification and dust removal facilities, the concentration of pollutants in atmospheric emissions all meet ultra-low emission requirements; long-discontinued businesses in the pre-production must be restored owned ultra-low emission coal-fired units to complete the transformation; gradually shutting down key areas do not have the conditions for the transformation of high-polluting coal-fired captive power plants; emission concentration of air pollutants new coal-fired gas turbine generator set to achieve set emission limits; the country City and Ningdong Management Committee in conjunction with the region's environmental quality improvement requirements, and actively promote the transformation of ultra-low emissions to arrange more than 65 tons of steam per hour of coal-fired boilers.
After the completion of the transformation project, owned coal-fired power plants should entrust a third party consultant for technical performance, environmental effects, equipment stability, comprehensive assessment, evaluation findings and issue.
In order to encourage enterprises to increase efforts to transform ultra-low emissions of pollutant emission concentrations below the pollutant discharge limits set by the state or place more than 50 percent, halved implement environmental tax policy. At the same time, we encourage financial institutions to give preferential credit support, to support eligible owned coal-fired thermal power enterprises to issue corporate bonds direct financing, to raise funds for ultra-low emissions and energy saving. According to the regional administration of appropriate incentive funding arrangements, to ultra-low emission reduction projects included renovation crew around them, give appropriate incentives based on emission reductions, combined with local conditions to increase financial support.
"Plan" requires all localities and departments should strengthen daily supervision and inspection of law enforcement to prevent corporate fraud, is not scheduled to complete the transformation of the self-ultra-low emission thermal power phase-out, discharge permit authorities to promptly subtract the emissions permit, for non-compliance business severely dealt with according to the law, to the public.
