Is it better to switch a coal-fired heat transfer oil furnace to natural gas or biomass fuel?

Have the two teams come for a penalty shootout to conduct a technical and economic comparison.

That’s for sure, but I first need to do my homework thoroughly; otherwise, how can I tell who is telling the truth? You see, once a decision is made to take action, real money is involved. It’s not just the initial renovation costs; there are also the subsequent operating costs and risk considerations to take into account.

Between natural gas boilers and biomass boilers, which one has lower operating costs? . . . . . . Natural gas has higher operating costs than biomass. If the biomass source can be guaranteed, it is better to use biomass.

Of course, operating with biomass has low costs, provided that the use of biomass boilers is allowed in the area.

Based on the information I have, the cost of biomass is the lowest. But where do my concerns lie? Now that I am considering switching to biomass fuel boilers, I have a few concerns: First is the issue of supplying biomass fuel; in other words, its supply is not as stable as that of commodities such as coal and natural gas ； To put it simply, its cost is very low at the moment, but I can’t predict how much it might increase in the future. If there is a shortage in the future and biomass fuels see sharp price increases, then those high prices will have to be accepted. Secondly, it is the stability of its calorific value and the **regulation thereof ； The calorific value of biomass fuel varies depending on the process and materials used, which may affect heating performance ； The local attitude toward this biomass fuel is such that, although it is considered a renewable energy source these days ； However, its impact on the environment is still significant. In other words, once the regulations imposed by the relevant departments become stricter, and the fuel burned by the suppliers of biomass fuels fails to meet the requirements set by the environmental authorities, do I still need to consider switching to natural gas? It’s mainly these two issues that are causing trouble; I hope those who have used biomass fuel can come forward to provide answers.

Natural gas boilers are the preferred choice, as they are mature and stable. Domestic biomass boiler technology is not yet mature; it has only been developed for a few years, with even less operational experience. Boilers also have to deal with issues related to corrosion, such as unstable fuel properties, unstable combustion, and high sulfur content. Furthermore, at the current stage, environmental protection issues are more pressing than energy-saving issues; if SO2, NOx, particulate matter, and other pollutants emitted by biomass boilers are not properly treated, they will not meet the required standards.

If you are the boss, choose biomass; if you are not the boss, choose natural gas.

For small boilers, natural gas is undoubtedly the preferred choice. Based on rough calculations, the cost of natural gas at this stage is three to four times that of coal, while the cost of biomass is 1.5 to two times that of coal. Biomass boilers actually burn a lot of coal.

I am a manufacturer of furnaces that use biological pellets; the cost is relatively low and the investment required is also modest. The investment for natural gas is higher, and the costs are greater as well, but natural gas allows for greater precision in temperature control, while the temperature variations with biological pellets are larger

Both natural gas boilers and biomass boilers have their limitations. The cost of natural gas boilers is 320 yuan per ton of steam, and it is likely that ordinary companies will not choose them unless it is absolutely necessary. Moreover, with biomass boilers, there is a lack of guaranteed supply of raw materials, and moreover, there isn’t enough space to store biological materials in such large quantities. My advice to you is to go with a coal powder boiler; it’s economical and environmentally friendly.
