8000 kg oil fired hot water boiler
How to deal with Henan, gas-fired burner fault? Henan burner gas boilers are generally spray liquid, gas combustion, so smooth fuel injection and ignition becomes a necessary condition, a German boiler summed up the four points of failure, namely, ignition misfire stick, stick ignition spark but not on fire, extinguished or flashing when the fuel injection instability intensified, large burner noise causes of these problems are not the same, a German Industry and Trade Co., Ltd. Weinan spent vigorously before collected over. The first reason, Henan gas-fired burner ignition misfire produced rod has several aspects, plugging cracks, moisture, leakage, ignition gap distances different rods, skin damage, short circuit, improper operation of these reasons are not generated timing of maintenance As a result, the fault is not present it is difficult to process, as long as the gas-fired burner cleaning Henan, renewal, lane changing from the ignition rod can be solved. Henan also gas-fired burner ignition spark rod is mainly due to clogging of misfire, poor ventilation, the throttle angle is set too small, the distance from the leading edge tip of the firing rod inappropriate oil nozzle, the first solenoid valve is heteroaryl oil gun clogging, strainer clogging the pump itself, water and other large oil, this solution needs to be more trouble Henan, gas-fired burner cleaning, renewal, debugging, testing and other means.
Structure and characteristics of Water Tube Boiler (double Longitudinal Tube Boiler)
The structure of the double vertical tube water tube boiler is mainly composed of upper and lower vertical tube, convection tube bundle, water wall tube, header box and down tube and other pressure-receiving components. The length of the lower drum is about half shorter than that of the upper drum. The empty space is provided with a furnace, a curved water pipe is arranged between the two drums, and a water wall tube is arranged around the furnace. The burning equipment adopts a gas/oil burner, and the tail flue has an economizer. The boiler evaporation is generally less than 20 tons / hour (t / h), the working pressure is less than 2.5 MPa (MPa). The high-temperature flue gas enters the rear convection flue from the right exit of the furnace, flows in an S shape along the two smoke-proof walls, flushes the convection tube bundle laterally, and then flows through the economizer from the left side of the furnace wall, and is discharged by the induced draft fan and the chimney.
Recently, Henan Province Industry and Information Technology Commission issued a public list on the Internet in 2018, Henan Province, manufacturing and integration of the development of pilot demonstration enterprises. Provincial and municipal levels of government through a rigorous screening, layers of review, the company boiler remote monitoring cloud services platform project as a key project in Anyang City was selected. Meanwhile, the provincial Industry and Information Technology Committee recommended that recommendation to declare: "The 2018 National Manufacturing and Internet convergence pilot and demonstration units."
Gas boiler burner failure how to do? Fault gas burning boiler opportunity arise, the most frequently occurring burner ignition rods gas boiler is not firing. The reason is concerned, it is because the ignition rods gap sandwiched carbon residue, oil phenomenon appeared, followed, that is because ignition rods chipping, moisture or leakage, furthermore, to stick ignition misfire, is because the distance between the ignition does not stick, too long or too short. Gas boiler burner ignition misfire rod, there may occur ignition due to the damage the insulation coating rod, ground short circuit; Then, since the ignition cable is transformer failure, including cable disconnection, connector damage caused by ignition when a short circuit; transformer disconnection or other failure occurs. When it comes to measures to deal with it is, it will include clearing, as well as new ones to adjust their distance, lane changing and changing transformers. Further, when we are faced with the ignition rod on the gas boiler burner spark reasons but misfiring, because the cyclone disc ventilation gap is blocked by carbon deposits, resulting in poor ventilation, or because the oil nozzle is dirty, clogged or is worn, it is because there is relatively small throttle angle setting. Gas boiler ignition spark rod misfiring but also may be due inappropriate firing rod tip from the leading edge of the oil from the nozzle (or protrude too retracted), moreover, the gun is because the first solenoid a valve clogging debris (small kerosene gun); if too viscous oily or not easily flow filtration system or re-clogging of the oil valve is not open, that the pump inlet is insufficient, low oil pressure. Finally, there is a spark ignition rods but misfire, because the pump itself or filter blockage in the oil because of its more water (boiling abnormal noise within the heater). For gas-fired boiler ignition spark stick but misfire, we must first be clear; the next, which is to be cleaned, such as not enough time to pay attention to new ones; furthermore, also is to pay attention to transfer a small test before they can .
