What is the oil consumption per hour of a 2 tph oil-fired boiler?
The oil-fired boiler refers to the boiler fueled by oil, including the diesel, waste oil and other fuel oil. The oil consumption of the oil-fired boiler affects the economic operation of the boiler.
The oil consumption of a 2 tph oil-fired boiler (per hour) = 3600*thermal power/calorific value/boiler thermal efficiency
The thermal power of a 2 tph oil-fired boiler is 1.4 MW. It is assumed that the calorific value of a kind of certain fuel oil is 42Mj/kg. The boiler thermal efficiency is 95%. It can be calculated that the oil consumption of a 2 tph oil-fired boiler per hour is 122 kg.
From the formula, we can conclude the factors affecting the oil consumption as follows:
1) Boiler thermal efficiency
There are many factors that affect the boiler thermal efficiency such as: exhaust gas temperature, calorific value of the fuel, boiler design, operating level of the boiler operator and so on. These factors may affect the boiler thermal efficiency. In addition, different boiler manufacturers also affect the differences in the boiler efficiency.
2) Fuel calorific value
Different oil types have different calorific values, so the 2 tph boilers with different fuels also ahve different oil consumption. What's more, the low calorific value of heavy oil is 44833kj/kg, the low calorific value of diesel is 10,200kcal/kg, the low calorific value of gasoline is 43062kj/kg, and the low calorific value of methyl alcohol is 4650kcal/kg.

See You in Dhaka on April 29 | ZOZEN Boiler Confirms Participation in BTKG 2026 Bangladesh ranks among the world's major garment and textile producing and exporting countries. Its extensive textile and dyeing industry maintains a consistent, concrete demand for stable and efficient industrial heat sources. From April 29 to May 2, 2026, the Bangladesh International Textile, Knitting & Garment Industry Exhibition (BTKG 2026) will be held at the ICCB International Convention City Bashundhara i...21 Apr 2026 -
In Pakistan, garment manufacturing and fabric processing remain important parts of industrial production. For these factories, steam is not an auxiliary utility but a core part of the production chain. Processes such as dyeing, drying, heat setting, and finishing all require a stable and continuous steam supply. Any fluctuation in steam output may affect production rhythm. Against this background, more textile companies in Pakistan are paying closer attention to fuel adaptability, operating sta...14 Apr 2026 -
Mongolia's industrial sector has been expanding steadily. Demand for reliable heat supply is growing — particularly in food and beverage manufacturing and urban district heating. Coal is the dominant industrial fuel. The continental climate means heating systems run for long periods each year. At the same time, factories are raising their standards for steam quality, equipment uptime, and emissions compliance. These factors together make boiler selection a more demanding process than it us...07 Apr 2026
