chain grate steam oil boiler
The main factors affecting small type gas chain grate steam boiler steam boiler thermal stability of gas ignition is not difficult to establish a stable small fire signal, the root cause is a small fire detectors can not detect normal to the fire. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing user fees biomass boilers categories: biomass boilers horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. Function gas boiler the ignition system that ignites the mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. A more secure electronic ignition system called ignition pulse, is widely used Zhuoyi energy saving gas boiler manufacturers. Which facilitate saving, can simply press a finger, and safe, does not occur due to unexpected accidents occur flame, once the stall state occurs, the control system can close the solenoid valve, off the gas passage. Small fire detectors use the ionization fire detection, and requires effective contact area of the flame, the flame stability and proper size, the gas pressure must be controlled within a very strict range. If the ignition gas pressure is too high, too long a small fire flame is moved beyond the detection range of the small fire detection probe, the system will not be mistaken for a small fire; if the gas pressure is too small, the gas will be firing too small and the boiler the blast very, very easy to blow out the flame, the ignition is not possible. Also, fire gases found a small pressure regulator valve regulating performance is not good, fine adjustment can not be achieved. Stability is also related to a small fire and the ratio of the size of the boiler furnace pressure boiler feed valve. The damper is too large or too small can affect the stability of the flame is ignited and the flame, furnace pressure will lead to extinguish the flame. In order to ensure the accuracy of fire detection, fire detection, we can adjust the small depth of insertion of the probe, the position of the fire detection probe in the correct position, in order to more effectively detect small fires flame.
Recently, we learned that the city of Zhangjiakou Yuxian environment departments to carry out a special investigation of coal-fired boilers, coal-fired boilers have complete control of the number of the county, painstaking, and practical coal-fired boiler renovation work to ensure safe and stable environment of the area.
The action focuses on the central heating pipe network has access to the dismantling of coal-fired boiler units, still use coal-fired boiler heating key units of 18 coal quality, coal to electricity station uniform implementation of the 1001 residents of coal-fired heating boilers civilian electric boiler furnace demolition and safe usage, the main city of 39 sets of bath boiler operation of treatment facilities, boiler demolished nine agriculture-related enterprises from coal to gas and gas safety carried out a detailed examination. Unit 4 of the use of substandard coal, the filing be investigated according to law, for gas safety problems 9 agribusiness, notify the county Emergency Management Agency and the territorial towns to regulate the management of its duties, to further prevent security incidents from the source .
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 chain grate 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.
Factors affecting boiler gas consumption SZS20 tons of gas vapors which gas consumption is influenced by three factors: 1. Calorific value of the fuel; 2. Boiler thermal efficiency; 3. Operating level fireman. So, if you want to consume as little fuel boiler over a period of time, there are several options: 1. Select efficiency gas furnace. A gas boiler type on the market a lot, have a variety, the price is different. Thermal efficiency between 85% to 95%, the heat efficiency is different from different manufacturers. Small boiler factory price is relatively low, but poor results. A price is true, so when the time to buy, do not look cheap, money is to buy a truly efficient boilers in the price. 2, select high calorific value gas. Different heating values of different fuels, different fuel heating value different origin. Just like oil, it is oil, but at a different price, per kilogram a few kilometers of oil is different. Of course, high calorific value, the price is relatively high. At the time of purchase, a good trade-off affecting the relationship between the price of both. 3, find an experienced operator. Regardless of the industry, when recruiting is like looking for the same experience, because experience is a treasure, you can do more things for the enterprise to save a lot of energy. Boiler workers, too, they save more money than those without experience. An experienced operator on a gas chain grate steam boiler can save 10 tons in addition to the cost of about 100,000 yuan, the user is also very worried about another problem: 10 tons of natural gas steam boilers. Specific cost depends on the manufacturing process, brand, product quality and other manufacturers.
