Yes, it is recommended to turn your boiler off whilst the tank is being filled and to leave it off for a short period afterwards of up to 30 minutes. This will ensure that any sediment that has settled on the base of your tank is not stirred up and drawn into your fuel line.
1. In terms of boiler body structure, WNS series gas-fired (oil-fired) boilers are fire tube boilers; SZS series gas-fired (oil-fired) boilers are water tube boilers;
2. In terms of boiler working pressure, if the boiler pressure is below 1.6Mpa, the choice is usually the WNS series gas-fired (oil-fired) boiler, if the boiler pressure is above 1.6Mpa, the SZS series gas-fired (oil-fired) boiler may be a better solution. Some high-pressure boilers also adopted SZS series gas-fired (oil-fir...
(Question details) Specific performance:The temperature difference between the inlet oil and the outlet oil temperature of the boiler exceeds the given value.Answer：Cause of failure:(1) The oil supply of the heat oil circulating pump is insufficient.(2) The boiler operates overload.(3) Thermal oil metamorphism.(4) The boiler does not match the heating equipment.(5) Bad insulation effect.(6) There is gas or steam in the thermal oil. Troubleshooting:(1) Remove the faults of oil pump and pipeline.(2) Operate at normal load.(3) Change new oil.(4) Choose proper boiler.(5) Check the insulation layer and repair the loopholes.(6) Remove air or steam. ZOZEN pays much attention to boiler furnace insulation also, the inside is made of high quality insulation material, external use of stainless steel plate, which can maximumly reduce heat loss and improve the operating environment.
(Question Details) Specific Performance:Broken coal is one of the most common failures of the coal feeder. The coal feeder is the lifeline of the boiler. Its normal operation is the basic guarantee for the normal and stable operation of the boiler, because it’s common occurrence that the coal feeder breaks the coal, especially when multiple coal feeders broken coal simultaneously, the improper handling resulting in overheating, explosion, coking, shutdown and other failures. Answer：cause of failure:(1) The particles of fluidized bed boiler fuel are coarse, but the fine particles in the fuel have a large amount of moisture. It is very easy to bond, resulting in the clogging of coal bunker and coal feeder.(2) Coal particles are jammed and squeezed in the coal feeder, causing the coal feeder chain to break.(3) Impurities in coal, such as woven bags and tree blocks, enter the coal feeder, causing coal feeders to jam, blockage, trip and break pins. Troubleshooting:(1) Fluidized Be
(Question details) Specific performance:The wall thickness of several boiler tubes was significantly reduced in a large area, the remaining wall thickness was 2.0mm, and some furnace tubes were corroded and worn out. Furnace tube wall is covered with a thick layer of uneven scale, the surface of the scale is brick red and black, scale layer is loose, and it is easy to remove the inner wall of the furnace tube, after removing, the furnace tube wall covered with a layer of corrosion pits. There is a thin layer of brick red corrosion on the outer wall of boiler tube, some of which are attached with black adhesive. Answer: Fault reason:1. The boiler is seriously short of water.2. Poor water circulation and uneven combustion.3. The unqualified quality of the boiler water and undemanding chemical supervision make the inner wall of the pipe corrode and scale, causing the pipe overheat and reduction of the strength.4. Due to the presence of impurities and scale, the furnace tube is blocked ins
