As the name suggests, oil-fired boilers use oil fuels such as heavy oil and light oil to transport hot water or steam to the outside world, providing power to all industries in which the society produces and lives. The main features of the oil-fired boiler are energy conservation, environmental protection, and intelligent operation. The better the environmental protection effect of the boiler, the lower the gas consumption, the less the operating cost of the boiler. Regarding how to calculate the fuel consumption and fuel consumption of oil-fired boilers, many users are confused, FANGKUAI Boiler will answer your questions.
How to calculate the oil consumption of oil boiler?
Oil consumption = boiler output / Fuel calorific value / Boiler thermal efficiency;
For example : Oil consumption of 1 ton oil fired boiler
1. The output of a 1 ton oil-fired boiler is 600,000 kcal;
2. Assume that the boiler uses diesel as an energy source with a heating value of 42.42 MJ/KG;
3. The boiler thermal efficiency is calculated according to 92%;
The fuel consumption of a 1 ton oil boiler = 600.000 kcal 92% ÷ 42.42 MJ / kg = 65 KG.
The above formula is applicable to oil-fired boilers under rated operating conditions, which is an ideal value. However, in the actual operation of the boiler, the operating load and pressure have changed, and even the operation mode of the furnace workers is inconsistent, which will affect the fuel consumption of the boiler. Therefore, the fuel consumption of oil-fired boilers cannot be generalized.
How to reduce the oil consumption of oil boilers?
The decisive factors affecting the fuel consumption of the fuel boiler itself are: boiler heating area, fuel calorific value, fuel purity, boiler convection heating area, boiler radiation heating area and so on.
1. The heating area of the boiler is inversely proportional to the fuel consumption. The larger the heating area, the less fuel consumption.
2. The fuel calorific value is inversely proportional to the fuel consumption. The higher the calorific value of the fuel, the less fuel consumption.
3. The fuel purity is inversely proportional to the fuel consumption. The higher the fuel purity, the higher the heat value and the less fuel consumption.
4. The convection heating area of the boiler is inversely proportional to the fuel consumption. The larger the convection heating area of the boiler, the less the fuel consumption.
5. The radiation heating area of the boiler is inversely proportional to the fuel consumption. The larger the radiation heating area of the boiler, the less the fuel consumption.
In addition to the boiler itself, the fuel consumption of the oil-fired boiler is closely related to the furnace experience of the furnace. Not only the fuel consumption of the boiler, but also the safe operation of the boiler is also very important. Therefore, the relevant state departments stipulate that the furnace workers who are on duty must have the certificate of the furnace, which is responsible for the users, the furnace workers, and the society.
