viessmann gas boilers salmon plumbing heating
Primary air tube blockage is what causes? How to prevent? Reason: 1) blocked or coked-burner fire nozzle inlet is blocked portion of small oil gun and other debris. 2) too many impurities coal, powder machine speed is too high, the pulverized coal and primary air speed too low. 3) powder machine speed is too high, too much under the powder without timely blown away. 4) a low pressure (throttle open or not to open too small), can not take away meal. Precautions: 1) to the powder and the rotational speed of the unit load and adjust relevant primary pressure according to the powder not more than 700 rpm rotation speed, a wind speed of each holding 25 ~ 30m / s, the mixed primary air temperature was controlled at 180 to 250 ℃, a pressure depending on the load, depending on coal, in the range 2.5 ~ 3.8kPa. 2) find a wind speed is too low, the primary air temperature is lower than the normal value should be to lower the rotation speed corresponding to the normal to the powder of a primary air temperature and wind speed. 3) open, gas steam viessmann boilers salmon plumbing heating tank should be fully cut-off torch powder, the powder in the tube is blown accumulated powder. 4) Fire mouth clogged or coked should try to remove. What causes large vibrations induced draft fan? 1) motor bearings in oil, resulting in large vibration and bearing wear; 2) even when the shaft is mounted on the center not good; 3) induced draft fan stall surge; 4) anchor bolt loosening induced draft fan; 5) blade fouling or wear ,lost balance.
To improve the quality of atmospheric environment, the Xinjiang Uygur Autonomous Region issued a "Xinjiang Uygur Autonomous Region Air Pollution Prevention Act" (hereinafter referred to as the "Regulations"), adhere to all the people involved, the source of governance, planning ahead, treating the symptoms, cooperative control, damage to bear responsibility in principle.
First, governments at all levels should implement the total coal consumption control system, adopt economic and technical policies and measures to reduce the total coal consumption, encourage and support the development and utilization of clean energy, and guide enterprises to develop clean energy alternatives to reduce coal production , use of atmospheric pollutants, emissions during the conversion.
Second, the regional government development and reform departments shall, jointly with relevant departments, according to the needs of economic and social development and regional environmental resources carrying capacity and other conditions, the development of total coal consumption reduction targets and control programs. State, city (prefecture) and county (city, district) people's government development and reform departments shall, jointly with relevant departments, according to the planning and control total coal consumption reduction targets, total coal consumption in the region to develop control plans and their implementation.
Third, promote urban built-up areas, industrial parks centralized heating, use of cleaner fuels. Before central heating pipe network coverage area, prohibit new construction, renovation, expansion of coal-fired heating boilers, central heating pipe network coverage, has been built using coal-fired heating boilers should stop using the deadline. In areas not covered by the central heating to encourage the use of clean energy alternatives, to promote the use of environmentally friendly energy-saving boiler. When the deadline out of the city government does not comply with national and regional scale coal-fired boilers.
Fourth, according to the city government to improve the quality of atmospheric environment requirements, delineated and publish high-pollution fuel combustion zone ban, and gradually expand the scope of the ban on high-pollution fuel combustion zone. In the combustion zone ban, prohibit the sale, burning polluting fuels; prohibit new or expanded high-polluting fuel burning facilities. Have been completed, should switch to clean energy within the prescribed time limit.
Fifth, governments at all levels should strengthen civil bulk coal governance, prohibit the sale does not meet the civil standard of quality coal for coal, to encourage residents to burn with high-quality coal and clean coal, to promote energy saving stoves, and promote the development of alternative and clean energy in rural areas use. Encourage rural energy-saving housing.
With the viessmann boilers salmon plumbing heating safe handling of air pollution is getting worse, many people began to use instead of using boiler coal boiler, but when we use, there are some things to draw attention to the safe operation, the following'll tell you about safety equipment Notes on operation: 1, inspection of electrical installations, mainly: whether the damaged wire, jacket damage, without loosening the screws, the contact is good, the motor is running any abnormal sound. 2, during startup, the boiler if the alarm is repeated locking reasons should be identified to locate the fault and then press the reset button to exclude (reset button is pressed no more than 10 seconds), continue to start. 3, during normal operation, and close to thermodynamic device portion (such as a flange connection part) will be very hot, to avoid burns. Do not place near flammable materials, so as not to cause a fire. 4, in the long-term shutdown state, to do maintenance work on the boiler equipment, for each transmission parts to clean, lubricate. 5, the working environment must be kept clean and dry, cleaning and maintenance once per shift to the control circuit must not get wet, affected by high temperature. 6, fireman shall not chaos tune, abnormal promptly notify management personnel, approved by management and then make adjustments. 7, the total gas pipeline experienced a temporary power outage will automatically close the solenoid valve to stop gas supply, the boiler after the first call to be electrically brought alarm device, after a small total hammer solenoid valve to the hand pull should first transmission to manually open solenoid valve, solenoid valve will be closed and vice versa total. With increasingly stringent national emissions standards for air pollution, the application instead of coal-fired boilers, very environmentally friendly, will not produce secondary pollution, but we still use the device must first understand clearly the right way to operate, to avoid the risk of accidents .
Method of reducing the exhaust gas temperature of the viessmann boilers salmon plumbing heating which: standard boiler exhaust gas temperature: between the boiler flue gas temperature of 200-230 deg.] C in accordance with conventional design national standard thermodynamic calculation boiler design requirements. Conventional exhaust gas temperature selected reasons, coal fired boiler combustion process will produce a certain amount of SO2, and SO2 below 170 ℃ will bind and generating flue gas H2O H2SO4 sulfuric acid, H2SO4 sulfuric acid and will form boiler heating surface of tail corrosion, thereby reducing the life of the boiler, conventional coal-fired boiler exhaust gas temperature is higher than 200 ℃. Temperature is high energy loss and more, is not conducive to energy saving. Cooling measures taken to ①, the economizer application: increasing the boiler economizer (economizer) of heat transfer area, larger than the conventional take about 1-2 times the flow cross sectional area economizer structure, effectively reduce smoke flow rate, to strengthen the heat transfer efficiency, reduce exhaust gas temperature; ②, air preheater applications: pipes connected to the air preheater economizer disposed, the apparatus can effectively increase the temperature of the combustion air, improving the ignition of the fuel condition. Very beneficial to the boiler combustion conditions. ③, adjust bidirectionality combustion system, a boiler originally designed for fuel specifications have some flexibility, different media in effect outside the combustion process are different, adjusting the embodiment, with the economizer and the air preheater using, the temperature of the boiler exhaust emission control at a suitable temperature, that make full use of heat energy, but also to ensure the integrity of the structure and function of the relative equipment, environmental protection, energy saving, security and development is the social responsibility of all of us for a rational design of industrial structure boiler, thermal efficiency is relatively high, its emissions would be relatively low temperatures, so we must be careful when choosing a boiler boiler property report form.
