With the increase of air supply volume, the mixture of oil mist and air is improved, which is beneficial to combustion. However, if the air volume is too large, the furnace temperature will be decreased and the incomplete combustion loss will be increased. At the same time, the heat loss of exhaust gas will be increased and the power consumption of the fan will be increased because of the increase of flue gas. If the air volume is insufficient, the combustion will be incomplete, resulting in carbon deposition at the tail, which is prone to secondary combustion accidents. Therefore, each hotel boiler supplier should pass the thermal efficiency test to determine its economic air volume at different loads. In practice, the stoves usually take into account the ignition of the nozzle and the carbon dioxide or oxygen content in the flue gas. Content to adjust the supply air volume. If it is found that the combustion condition of a nozzle is not good, or if the atomization plate with different aperture is replaced, the air pressure of the supply duct should be kept unchanged, and the opening degree of the duct baffle of the nozzle should be adjusted to normal combustion. If the fuel quantity changes due to the change of the oil pressure in front of the furnace, the opening of the fan baffle should be adjusted to achieve normal combustion by changing the air pressure and air volume of the air supply duct when it is necessary to adjust the supply air volume.
3) the observation and analysis of all kinds of flame when adjusting the fuel oil. Generally through the fire point adjustment and flame center adjustment to complete the flame adjustment. The ignition point of the oil mist should be close to the nozzle, but there should be no tempering. Early ignition is beneficial to complete combustion and stability of oil mist. However, the fire is too early, too close to the nozzle, easy to burn the nozzle and furnace wall to determine the mouth. Furnace temperature flying oil varieties and atomization quality, as well as air volume, wind speed and oil temperature, will affect the distance and proximity of the ignition point. So if you want to adjust the ignition point, you should find out the cause in advance, and then take targeted measures. When the boiler load is constant and the oil pressure and oil temperature are stable, Should be based on the ignition point wind speed and wind distribution situation.
Young workers from Tianjin, said the training is very timely, went through the last heating period we have a lot of operational settings, fault verification, exclude doubt want to learn the skills, the training targeted and very practical, lecturer lectures easy to understand, is a rare and rewarding "charge" in the hope the group can fast side of this type of open class continue gone out of existence, we have a great need for such training.

Steam hotel boiler supplier pressure gauge should pay attention to matters 1, rated steam pressure less than 2.45MPa steam boiler and pressure gauge accuracy not only in 2.5; rated pressure steam boiler child or equal to 2.45MPa, the pressure is too spread made not less than 1.5 level. Dial gauge diameter of not less than 100mm, in order to ensure the operation of the operator to see the surface of the pressure value shown. 2, should draw the red line on the dial gauge steam boiler, he pointed out that the maximum allowable working pressure. 3, the steam boiler pressure gauge should be provided at a convenient place to observe and purging, and to prevent the high temperature affected, freezing and vibration. 4, steam boiler pressure gauge should check at least every six months once the check should seal. 5, the pressure gauge connection tube steam boiler should leaks steam leakage phenomenon, otherwise it will reduce the pressure instruction value. 6, a steam boiler gauge scale element should be compatible with the measured working pressure, working pressure, typically 1.5; 3 times, preferably 2 times. When no steam boiler gauges, pressure gauges or pressure damage did not meet the requirements of the apparatus, boiler steam pressure gauges of the following circumstances, should stop using: 1, the surface glass breaking or blurred dial scale; 2, no seals , damage or seal verification period exceeded; 3, no pressure gauge pointer finite bit staple staple can not be restored to the limit at infinite set of bits from zero gauge pressure exceeds the pressure data bits garment allowable difference?; 4, the jump table or a pointer leak; 5, other effects gauge accurate defect. The use of the accumulator: the accumulator for a hydraulic accumulator system intermittent mechanical, hydraulic fluid may be stored in the actuator output when a batch or a low speed, and the actuator requires a large flow of fast-moving, as an auxiliary energy providing oil to the system together with the hydraulic pump, oil pump and thereby achieve miniaturization of the entire hydraulic system, to achieve the object of absorbing the impact energy sudden change fast opening and closing valve and the hydraulic load, the system generates a pressure shock, pet cause vibrations and noise, and even damage the machine. The accumulator can be alleviated, which absorb fluid shock absorber pressure pulsation absorbing accumulator, and reducing the pressure pulsation and flow pulsations of various pump, thereby reducing system noise and vibration. Having a damping effect of the gas spring accumulator, it can be used to absorb the mechanical vibrations between the body and the traveling wheel of the vehicle and the like. The accumulator can be balanced upright actuator (hydraulic cylinder) and gravity load decreases when the potential absorption into hydraulic energy store, while generating the rate-limiting resistance; upright when the actuator rises, releasing the original absorbing energy accumulator , together with the pump oil to the hydraulic cylinder, in order to achieve balance and energy.[email protected]
