Heating system classification:
1. Gas-fired hot air heating system (automatic) ---- the box-type oven is the first choice, and the continuous operation of the assembly line is also optional (the gas-fired system should be preferred for the box-type oven or the pipeline drying tunnel)
2. Coal-fired hot air heating system (semi-automatic) ---- the first choice for continuous operation of the assembly line, and the box-type oven is also optional
3. Oil-fired hot air heating system (automatic) ---- With the rising oil price, the operating cost is higher
4. Far-infrared electric radiation heating system (automatic)---high operating cost, but the equipment investment is the most economical, and ultra-small batch spraying can be considered
There are 3 energy supply methods for the gas-fired hot air heating system in operation by our customers:
1. Pipeline natural gas
2. Canned liquefied gas
3. Canned compressed natural gas
Simple permutation:
If environmental protection factors are not considered, and the heating system operates continuously, the operating costs from low to high are: coal, gas, oil, and electric heating.
If environmental protection factors are not considered, the heating system operates intermittently, and the operating cost is from low to high: gas, coal, oil, and electric heating.
Considering environmental protection factors, among the optional heating methods, the operating costs from low to high are: gas, fuel oil, and electric heating.
Among them, the consumption cost of fuel oil and electric heating is similar (the oil price is too high)
