Oil-fired boilers have two outstanding advantages: good safety and ease of use. Although their cost is higher than ordinary boilers, they are still very popular. The fuel consumption of diesel-fired steam boilers is one of the concerns of many customers of oil-fired boilers. As a clean energy boiler, light diesel is the most widely used oil fuel for oil-fired steam boilers. Although the current emerging methanol fuel is also environmentally friendly, diesel-based applications have accumulated more, so more customers are optimistic about diesel. In addition, the price of light diesel is indeed cheaper than methanol fuel. . So how much diesel does a diesel steam boiler consume per ton of steam?
Diesel oil can be divided into light diesel oil and heavy diesel oil. Diesel oil can be obtained by atmospheric distillation and vacuum distillation. Light diesel is diesel fuel, which is only used for ignition in the boiler; heavy diesel is medium and low speed diesel fuel, and it is only used as a combustion fuel at low load in some power plants. Diesel-fired boilers are small boilers.
How much oil is burned per day by an oil-fired boiler refers to the fuel consumption. There is a fixed calculation formula for the fuel consumption: Diesel boiler fuel consumption per hour = 3600 × thermal power ÷ heating value ÷ boiler efficiency. Under normal circumstances, the thermal efficiency of a 1 ton oil-fired boiler is 0.7MW, and its combustion heat value is 42.42Mj / kg. The efficiency of the oil-fired boiler is about 92%. Then, the daily fuel consumption of a 1 ton oil-fired boiler = 3600 × 0.7MW ÷ 42.42Mj ÷ kg / 92% = 65kg.
It can be seen that the fuel consumption of a one-ton fuel boiler is 65 kg per hour. The fuel consumption of other tonnages can be obtained by applying this formula.
