Heat transfer oil heating method
Thread Content
Hello everyone. My company is considering using heat transfer oil, and I’m not sure whether it would be better to use electric heating or to burn natural gas to heat the heat transfer oil Which method is cheaper? If natural gas is used for combustion, what kind of furnace should be used? What’s the efficiency? Thank you.
I have seen methanol-based hydrogen production facilities; the heat transfer oil furnaces use a combination of fuel and gas as energy sources. Initially, diesel or similar fuels are used, but later on methanol is employed. The choice depends on the capacity of the heat transfer oil and the amount of heat energy required.
Generally speaking, coal is the cheapest option; it depends on the region you are in as well as the size of the boiler. For our boilers with a capacity of 6 million kcal, the cost of gas is roughly three times that of coal (coal costs 450 per ton, while gas costs 3.2 per cubic meter); we haven’t calculated the cost of electricity yet.
Depending on your heat demand, electric heating provides a relatively lower amount of heat, but it has a very high thermal efficiency； Overall, coal-fired heat transfer oil boilers are the cheapest to operate. However, there are many restrictions on coal use in various regions, and fuel also causes pollution. Gas is the easiest option to implement at present, with a thermal efficiency of around 90%.
Hello, you might consider using solid-state thermal storage devices that make use of off-peak electricity; their thermal efficiency is 95%. Hu: 18605355305
It depends on the policies in your area. For electric boilers, it’s necessary to use off-peak electricity as this helps with heat storage; gas boilers are also a good option, as they are clean and produce no pollution. Check if there are any discounts available locally. You can figure out the cost by calculating it based on the local natural gas and electricity prices. I don’t know what size of furnace is needed; we have imported ones
Can a heat transfer oil furnace use residue oil as fuel?
Basically, fewer standard fuels are being used these days, as they are expensive; alternative options can be used instead. You can contact me at 15961187658 or QQ526313805
Coal-fired heat transfer oil furnaces are the cheapest to operate. If ultra-low emission environmental requirements are considered, a coal powder furnace can be used.
We have used all three types of heat transfer oil furnaces: electric heating furnaces, coal-fired furnaces, and natural gas furnaces. The electric option has been discontinued; the temperature in those furnaces was 160 degrees. Now steam is used instead. For the coal-fired furnaces, the temperature was 250 degrees, and due to environmental regulations, they have been converted to use natural gas. Currently, natural gas is used at a ratio of about 2.5 times compared to before. The natural gas furnace generates 2.4 million kcal of heat, with a consumption of around 110 cubic meters of natural gas per hour.
