For example, for home use, or some areas that need small fires, the effect is not ideal because there is no corresponding supporting equipment. Liquefied gas and natural gas have already entered thousands of households, and the corresponding supporting stoves and equipment are relatively complete.
If alcohol-based fuels are widely used in households, some problems will arise. First of all, the consumption is too small. The average household consumes 50 yuan every month, so your profit is about 20 yuan, including your delivery cost, the cost of replacing or refitting the stove, after-sales maintenance cost and various expenses.
Stove is very expensive. If you give it to them for free, they will have to spend at least 200 yuan (household stoves are difficult to change), so the initial investment is relatively large, and the return is too slow.
Safety issues, liquefied natural gas has become accustomed to, if something goes wrong, you can only admit that it is unlucky. If alcohol-based fuel is provided and a safety accident occurs, the estimation is not clear.
Hotels and canteens can do it, because the consumption is relatively large, and stoves and cookers are provided free of charge in the early stage, so you can return to your books soon, so you can do it.
