Oil-fired boilers mainly burn 0 # diesel, or light oil or heavy oil. The fuel oil quantity of the fuel boiler is mainly different from the heating method, and the fuel oil quantity is also different. The fuel consumption of the three types of fuel boilers is different, such as the fuel steam boiler, the fuel hot water boiler, and the fuel oil heat conduction oil furnace.
Let’s take a 4 ton diesel boiler as an example to calculate the fuel amount of three different boilers:
Calculate the fuel quantity of the fuel steam boiler. One hour of full-load operation is 240 kg of diesel (the price of diesel is calculated at 5 yuan / kg). The operating cost of the boiler includes electricity, water, labor costs, and diesel consumption. The cost price is 1350 yuan.
Fuel oil hot water boiler fuel volume calculation for a long time operation is an average of 200 kg of diesel oil (diesel price is calculated at 5 yuan / kg), boiler operation costs include electricity, water, labor costs, diesel consumption, etc., combined 4 tons of fuel oil The cost of boiler fuel oil is 1150 yuan.
Calculation of the fuel consumption of the oil-fired heat conduction oil furnace for long-term operation is an average of 185 kg of diesel oil (diesel price is calculated at 5 yuan / kg). The boiler operating cost includes electricity, water, labor costs, and diesel consumption. The cost of boiler fuel oil is 1,000 yuan.
The first advantage is less equipment investment. The fuel oil burns quickly, and there is no problem of furnace coking, and the furnace volume heat load is relatively high, which can be nearly double that of coal-fired boilers. In this way, the volume of the furnace is significantly reduced, and the boiler steel frame can be reduced accordingly. There is very little ash in the fuel, and the ash in the flue gas wears the heating surface of the tail very lightly. You can choose a higher flue gas flow rate to strengthen the heat transfer of the heating surface of the tail and reduce the heating surface of the tail. There is no need for huge pulverizing equipment, nor for the establishment of huge coal storage yards, ash storage yards and powder storage bins. The fuel oil system is very simple.
The second advantage is that due to the low ash content in the oil, the fuel and flue gas wear the equipment very lightly, and the maintenance and maintenance workload of the equipment is small.
The third advantage is that the fuel oil does not need to be further processed, and it is convenient to transport as long as the temperature is raised, and it can be sent to the boiler through the pump boost. Therefore, each ton of steam consumed by the oil furnace consumes less electricity.
The disadvantage of oil-fired boilers is that they consume a lot of precious high-quality fuel. Fuel oil is an important chemical raw material, and it is a pity to burn it as a large amount of fuel. In the current situation of energy shortage and high fuel oil prices, it is of great economic significance not to burn oil or to burn less oil.
