The current market in the use of the most coal-fired thermal oil furnace, but recently the state advocates energy saving and environmental protection, so the majority of users have cast their eyes on the gas-fired thermal oil furnace, which has a high degree of automation, and the start and stop quickly, safe and reliable operation, high thermal efficiency, stable output, load adaptability, compact structure, small size, small footprint, gas-fired thermal oil furnace supporting auxiliary less, easy and convenient to install, installation, short cycle time, gas-fired thermal oil furnace fuel combustion, less pollutant emissions, can achieve a higher level of environmental indicators and many other advantages. Short cycle, gas heat transfer oil furnace fuel combustion, less pollutant emissions, can achieve higher environmental indicators and many other advantages. Therefore, the gas oil furnace is an ideal high-efficiency, low-consumption, low-pollution green products. The following is a small introduction to the use of the process we need to pay attention to what:　　

1, gas heat transfer oil furnace the whole oil circulation system design to be soothing. Minimize elbows and valves. Selection of high-efficiency circulating pump. Timely cleaning of the filter, must ensure that the flow rate of heat transfer oil in the high temperature state is not less than 2m/s.　　

2, the correct choice of heating furnace (generally 1.5 times the nominal capacity of the selection of Ⅲ), to avoid overloaded operation and the proportion of uneconomical phenomenon. Heating furnace heating capacity selection is reasonable or not, not only relates to the safety and life of the heating furnace, but also affects the service life of the heat transfer oil and production costs.　　

3, the selection of thermal stability and oxidation resistance, anti-coking gas heat transfer oil furnace. Selection of gas heat transfer oil furnace should be careful not to choose the smell and color of the deep heat transfer oil. The service life of heat transfer oil is measured by four indicators: residual carbon, acid value, flash point and viscosity. Do a good job every six months of oil testing, in order to grasp the quality of heat transfer oil in operation. Problems found in a timely manner to replace the heat transfer oil, and find out the causes of premature deterioration of heat transfer oil and preventive measures. At the same time, we should strictly do not mix the use of different grades of heat transfer oil.　　

4, in strict accordance with the operating procedures using thermal oil boiler, to avoid rapid heating (its heating rate should be controlled at l0 ~ 40 ℃, h), over-temperature, over-pressure, emergency measures should be taken to stop the furnace should be rapid, decisive, at any time to observe the expansion tank oil level and oil temperature. If the lack of oil should be supplemented in a timely manner. Prevent air and moisture from entering the oil circulation system. Because of the high temperature heat transfer oil will accelerate the oxidation rate after direct contact with air (its oxidation rate in the temperature increases every l0 ℃ when the growth of 2 times), to prevent high-temperature oil directly in contact with air. A better way is to use nitrogen to seal the upper space of the expansion tank. The formation of a protective air film layer, in the absence of conditions for nitrogen sealing conditions. Generally to make the heat transfer oil temperature of the high tank does not exceed 60 ℃, the high tank is not directly connected in series in the circulatory system.　　

5, improve the thermal efficiency of the gas heat transfer furnace, timely removal of the inner wall of the furnace, coil line pipe wall of gray scale to ensure good heat transfer, while the coal should be used as much as possible to better quality, so that the heat generated by the coal combustion in a timely manner, comprehensively transferred to the heat transfer oil!　　

6, gas thermal oil furnace heat preservation shall not stop open thermal oil circulating pump when the furnace must be furnace temperature down to the prescribed range to shut down the circulating pump, each time the furnace should be opened first circulating pump. In the event of a sudden power failure or circulatory system failure, in addition to the use of ventilation cooling. Must also be replaced by cold thermal oil.
