Gas thermal oil boilers are widely used in petrochemical, textile, printing and dyeing, plastics, rubber, food processing, wood processing, asphalt heating, carton production, vegetable dehydration, baking varnish, casting sand mold drying, etc. And can also be used for baking at ≤ 350℃ , Steaming, shaping, melting and drying. The wide range of applications is mainly because the gas-fired thermal oil boiler has a very powerful function. Let’s take a look at the working principle of the gas-fired thermal oil boiler and understand its usage.
As we all know, this type of boiler uses heat transfer oil as the heat carrier. The circulating oil pump is used to force the liquid phase to circulate, and the heat energy is transferred to the heat-consuming equipment. Then return to the reheated DC type special industrial furnace. The working principle is very simple, you can see the schematic diagram of the gas fired thermal oil boiler to understand. However, although its working principle is relatively simple, we still need to pay attention to its use in the process of use.
When starting this series of thermal oil boilers, it is necessary to check whether the heating furnace and its surroundings are clean and free of debris. Check whether the furnace body, burner, controller, fire hole, chimney passage, etc. are normal. Turn on the power supply of the heating furnace control cabinet and check whether the voltage is normal. Check whether the indicator light and each display instrument are normal. Adjust the gas main pressure reducing valve and secondary pressure reducing valve to control the pressure to 0.005 MPa. The gas thermal oil boilers has less oil capacity, fast heating speed and long service life.
When starting the gas-fired thermal oil boiler, it is necessary to start the heat-conducting oil circulating pump (transport one, prepare one, refer to the water pump operation rules). Normally circulate for about 0.5 hours after starting the pump to stabilize the pressure. Reverse the process equipment and process, and check whether the oil level of the expansion tank is above the 1/4-1/2 level. Whether the thermometer, pressure gauge, etc. are normal. Press the burner start button and observe whether the furnace flame is burning normally. If it does not ignite, start the burner again after troubleshooting.
YYQW series thermal oil boiler adopts reasonable flow rate of hot oil and the overall consistency of flow rate. It is ensured that the furnace tube will not burst due to carbon formation. This not only ensures the safety of the boiler, but also extends the service life of the oil. The gas thermal oil boilers has high furnace temperature, high combustion efficiency and low exhaust gas emission concentration. Its sufficient heating surface and reasonable heating surface layout make the thermal efficiency of the boiler reach more than 95%.
