4 ton horizontal condensing gas fired 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 steam 4 ton horizontal condensing fired 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.

Selection and classification of fuel gas thermal control system fuel gas 4 ton horizontal condensing fired boiler 1. The boiler classification thermal control system (1) electric system for an electric meter instrument cluster system consists of relays, time relays, the relay program composed of program control and interlock system; manufactured by electronic control and intelligent series or digital instruments, measuring instruments display, sound and light alarm monitoring instrumentation and control system and other components. Electric instrumentation system design experience mature, the price is cheap, but it is difficult to achieve system redundancy, remote data transmission, maintenance is more difficult, more difficult to implement advanced control methods. Electric meter system is mainly used for small boilers, but the electronic control Applications for closed-loop regulation of decreasing almost been replaced by intelligent multi-function instrument, the following sections mentioned electronic control just want to take advantage of familiar industry and the series combination of a widely used instrument that time to explain the principles of the control system configuration and (2) programmable control system programmable control system is the core of programmable logic controller (PLC). Programmable logic controllers are widely used in the initial control, since the 1990s has increased the ability of process control, the programmable logic controller in the field of process control applications more widely.
