Description

technical field [0001] The invention relates to a boiler, in particular to a novel normal-pressure heat-conducting oil furnace. Background technique [0002] Heat-conducting oil furnace refers to a new type of heat energy conversion equipment whose heat-carrying medium is high-temperature heat-conducting oil (also called hot coal, heat carrier). The heated heat-conducting oil is transported to the heat-using equipment, and then returns to the heat-conducting oil furnace from the oil outlet of the heat-consuming equipment for heating, forming a complete circulation heating system. [0003] Existing heat-conducting oil furnaces generally use coiled tubes to be heated in the combustion chamber, and the medium oil in the coiled tubes is quickly circulated by means of pressurized forced circulation, and then transported to heat-consuming equipment. The fuel burns for a short time in the combustion chamber, and the hot air flows through the coil to absorb heat and is directly dis...

AI Technical Summary

Problems solved by technology

The existing heat conduction oil furnace has the following defects and deficiencies: the heating area of ​​the coil is small, the local temperature is high, and the energy consumption is increased

At the same time, because the coil is bent and the length is large, it is easy to cause the deposition of oil dirt and oil residue on the inner wall of the coil, hindering the oil circulation, and in serious cases, it is easy to cause safety hazards

The hot gas generated is directly discharged after being heated by the coil in the combustion chamber, and the waste heat of the exhaust gas cannot be used, resulting in energy waste and environmental pollution

The amount of heat-conducting oil used in the coil heating type heat-conducting oil furnace is small, and after being transmitted to the heat-consuming equipment, the temperature stability is poor, and the operation safety is poor due to the forced pressurization cycle

In addition, because the heat transfer oil contains a certain amount of water, it forms high-temperature water vapor after heating. Because the coil is bent and long, the water vapor is difficult to discharge quickly. The water vapor enters the heating equipment through the high-temperature oil pump with the heat transfer oil, which will affect the high temperature. The normal operation of the oil pump also results in poor thermal stability of the heat-using equipment, which affects the circulation speed of the heat-conducting oil in the heat-consuming equipment, thereby affecting the heating effect of the heat-consuming equipment
