How to Improve the Thermal Efficiency of Heat-Conducting Oil Furnace @Heat-Conducting Oil Boiler

At present, the combustion efficiency of heat-conducting oil boilers is very high when they leave the factory on the market, but if they want to achieve 100% combustion efficiency of boilers, heat-conducting oil boilers must be in the best environment. However, in actual operation, heat-conducting oil boilers often fail to achieve the best combustion effect, which will cause certain combustion losses. So let's see how we can minimize those losses in the operation of heat-conducting oil boilers in general.

Common measures are as follows:

(1) The waste heat recovery technology of flue gas is adopted to reduce the loss of exhaust smoke.

The main factor affecting the heat loss of exhaust smoke is the exhaust temperature. The higher the exhaust temperature, the greater the heat loss. At present, most of the heat-conducting oil furnaces @ heat-conducting oil boilers of Yongxin Boiler in Hebei Province are equipped with flue gas waste heat recovery devices when they leave the factory, such as energy-saving devices or fully condensing flue gas waste heat recovery devices. These measures can effectively reduce the flue gas temperature and improve the thermal efficiency of heat-conducting oil furnaces.

(2) Reasonable control of air-fuel ratio, optimization of combustion, reduction of incomplete combustion loss and heat loss of exhaust gas.

When excess air coefficient is too high, it is equivalent to inhaling excess cold air into the furnace. This excess cold air does not participate in combustion, but is discharged white after heating, and the heat loss of exhaust smoke increases.

If the cold air entering the furnace continues to increase and exceeds a certain limit, the furnace temperature will decrease and the incomplete combustion loss will increase. When the excess air coefficient is too low, the incomplete combustion loss will increase because the fuel can not get enough oxygen to burn completely. However, the long-term serious incomplete combustion will lead to the heating area carbon of the boiler, affect the heat transfer efficiency, and increase the exhaust gas loss. Therefore, reasonable control of air-fuel ratio, as far as possible to reduce exhaust heat loss Q2 and incomplete combustion loss q3, is another key point to improve the thermal efficiency of heat-conducting oil furnace @ heat-conducting oil boiler.

(3) Strengthen heat preservation, prevent leakage, and reduce heat loss.

Because the temperature of the main body of the heat-conducting oil boiler and the heat pipe system of the heat-conducting oil is higher than that of the air in the boiler room, part of the heat will be lost to the surrounding air by radiation and convection, which will become the heat loss of the heat-conducting oil boiler. Therefore, when the insulation layer of heat-conducting oil boiler and heat-conducting oil thermal pipeline system is damaged or leakage is found, it should be repaired in time to reduce heat loss.
