Industrial WNS 1-10ton fire tube 3 pass oil fired steam boiler

Industrial WNS 1-10ton fire tube 3 pass oil fired steam boiler

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 industrial wns 1-10ton fire tube 3 pass fired steam boiler 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.

Combustion Adjustment of dual-use oil and gas boilers (Skills) boiler firing was successful, the load can be adjusted to normal operation. At this point, we should always observe the furnace combustion, if there is a bad oil and gas atomization, beating the flame, the flame hit the furnace and the exhaust gas temperature is too high or too low and so, it is timely for oil pressure, oil temperature, of steam, wind, air pressure, steam pressure hanging line adjustments to ensure safe and economic operation of the boiler. Size and load size of hydraulic, pneumatic boiler related to the oil pressure adjusted by adjusting the back pressure or fuel burner to achieve the size, by adjusting the air pressure to achieve the degree of opening of the valve. Adjust the amount of oil, air pressure adjustment load, at the same time, air volume control, must be synchronized to ensure a reasonable match of oil and the amount of wind, so as to achieve economic operation of the boiler. 1, the combustion method of determining boiler fuel gas: C02 content is determined from the flue gases and excess air ratio (1) the combustion quality (2) determines the length of the flame from the combustion quality (3) from the flame color and smoke color determination 2 is good or bad combustion, fuel combustion boiler adjustment method: the normal combustion, furnace flame stability was white orange, generally rumble, or if the flame beating abnormal sound, should adjust the fuel and air volume. If the adjusted still no improvement, it should identify the cause flameout, the measures to be taken and re-ignition.

High resistance industrial wns 1-10ton fire tube 3 pass fired steam boiler gas handling system: 1, gas steam boiler pressure gauge, water level gauge, safety, sewage, a water supply valve, a steam valve, check whether the performance requirements, other valves in good condition. Gas hot water boiler with environmental protection, energy conservation, safety, salient features fully automatic operation, and ease of use. In addition, due to the operation of the economy, government policies to encourage, gas hot water boiler more and more people of all ages. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. 2, the boiler Zidongkongzhi device system, comprising a flame detector, level, temperature detection, a variety of interlocks and alarm means, display control system performance states to meet the requirements. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace.

From March 18 to start, Lujiang County, Anhui Province north of the Market Authority on the area of ​​internal security to carry out a special inspection of boiler pressure boiler; To ensure the safe operation of this special equipment, complete elimination of security risks.

The inspection mainly troubleshoot and eliminate hidden dangers in the management and operation of the boiler links exist, focus on examination of whether to establish safety management systems and procedures; whether to set security management or part-time security management staffing; whether workers with valid work certificate for employment; boiler operating records, inspection records and shift recording is complete; if the boiler for the use of registration; whether the inspection within the validity period; check valve is within the validity period, the pressure gauge whether the test within the validity period. Up to now, law enforcement officers dispatched 27 people, focus on examination of 12 times the focus of special equipment supervision units, hospitals, schools, boiler 20 times, do not meet the specified use in accordance with the boiler "Special Equipment Safety Law of People's Republic of China." requirements, issued a supervision instructions, requires immediate rectification unit, for there is no regular inspection of boilers or unqualified, shall not be put to use.
