Does the circulating pump damage the diesel burner of the boiler? What are the emergency measures?

If the internal high-temperature circulation pump fails during the heating process of the thermal oil boiler diesel burner, what are the emergency measures? 1. When the thermal oil boiler diesel burner is working normally, if the circulating pump current in the internal high-temperature voltage system is lower than the current value during normal heating, it indicates that the heating efficiency of the internal circulating pump has been significantly reduced. This situation may be caused by the fouling of the internal heating pipe, which should be cleaned up in time. 2. When heating, the voltage of the circulating pump remains unchanged, the current value increases while the flow value decreases. The reason for this may be the deterioration of the liquid caused by internal heat. If it is a new heat transfer fluid, it may be due to the moisture in its internal voltage or gas blocking the system under high temperature voltage. The valve should be opened in time to remove the fluid. 3. Reduce the current value of the internal circulation pump. When the outlet voltage pump value is in the initial state, it means that the internal circulation pump is idling without oil supply. It may be oil vaporization, find out the cause of the corresponding measures and remedy; if the filter is clogged and the circulation pump has been emptied, please open the side channel to clean the filter in time. If the newly added heat transfer fluid contains water or water, the decomposition gas cannot be removed in time in the system, and the valve should be opened to discharge the gas. 4 The exit temperature of the liquid phase heat carrier furnace is low, the heating is insufficient, and the exhaust gas temperature exceeds 300°C. The main reason is the ash problem. Soot should be blown in time. If the exhaust gas temperature is low, it is mainly a combustion problem, mainly a lack of wind. Although the furnace is under positive pressure, the blast volume is not open, the temperature of the furnace is low, and the combustion intensity is not enough. It is important to check whether the water seal of the slag remover and the exhaust port of the dust collector at the rear of the furnace are well sealed and whether there is a large amount of cold air leakage. 5. When the pressure difference of the filter equipment increases and the pressure of the pressure pump port drops, it may be that the material in the filter screen is blocked, so it should be cleaned when applying. 6. When the grate in the thermal oil boiler diesel burner does not work, check whether the chain is too loose, whether the sprocket gear is bad, or the chain is worn seriously. At this time, the measures that should be taken are to adjust the length and distance of the screws to tighten the grate. If it still does not work properly, replace the entire sprocket. 7. When the grate of the thermal oil boiler diesel burner is stuck. It may be that the grate piece is broken or the pin falls off and the grate piece is loose; metal inclusions in the coal block the grate; the grate plate is arched; the tip of the slag baffle (eagle iron) sinks to block the grate. Treatment: Turn the grate upside down to remove debris and replace the broken grate before starting. If the grate gets stuck after starting, correct the valves on both sides before starting the furnace. Equipment system composition Feeding system The feeding system consists of a silo, a vibrating feeder, a screw feeder and a screw feeding tube. The BMF fuel processed in the factory is transported to the storage bin through a belt conveyor, and then sent to the burner through a screw feeder for combustion. In order to ensure the stability of continuous feeding and material transportation, a vibrating feeder is connected between the material box and the screw feeder. Combustion system The combustion system consists of burners, fans, igniters and other components. The biomass fuel in the burner first undergoes a preheating process, and then the fuel is delivered to the furnace for combustion through a fan. BMF fuel contains a high level of volatiles. When the temperature in the furnace reaches the temperature at which the volatiles are released, the igniter fuel can quickly catch fire under wind conditions. The burner temperature control is based on the internal temperature of the furnace, its temperature and the amount of air supplied during fuel gasification. The adjustment of the boiler diesel burner load is controlled by the adjustment of the feed volume. The combusted flue gas enters the convection flue through the furnace chamber for heat transfer, then enters the dust collector for purification treatment, and finally is discharged to complete the entire process of combustion and heat transfer. The boiler diesel burner of the blowing system is equipped with an automatic soot blowing device, which can periodically purge the furnace cavity and flue pipe to ensure that no dust accumulates on the surface of the flue pipe, thereby achieving safe and efficient operation of the boiler diesel burner. Gas supply system of flue gas system: The integrated arrangement of the gas supply system of the boiler diesel burner and the burner, the air is sent to the furnace through the blower to realize the function of fuel oil delivery and combustion. Suction and dust removal system: Under the action of the induced draft fan, the high-temperature flue gas generated after the combustion is completed through the convection heat transfer in the flue pipe enters the dust collector for purification, and finally exhausts the induced draft fan from the chimney. Automatic control system The control system adopts high-brightness full Chinese display, and the famous PLC control system is the central control unit. In the man-machine dialogue mode, exchange information with boiler diesel burner users to realize the fully automatic operation of BMF boiler diesel burner. !
