The heating method affects energy cost, factory infrastructure and control strategy.
Gas Heating
Potential advantages:
* competitive energy cost in gas-rich markets;
* common in large industrial frying systems;
* suitable for substantial thermal loads.
Considerations include:
* gas train;
* burners;
* ventilation;
* combustion safety;
* local gas regulations.
Electric Heating
Potential advantages:
* no on-site combustion;
* simpler installation in some factories;
* precise electrical control;
* compatibility with factories using renewable electricity.
Potential disadvantages include high electricity cost or large electrical infrastructure requirements.
Compare Energy Cost Properly
Do not compare only:
price per cubic metre of gas
versus
price per kWh of electricity.
Instead calculate:
Useful heat cost = Energy unit cost ÷ Effective system efficiency
Different heating architectures have different losses.
Other Decision Factors
Consider:
* local utility availability;
* grid capacity;
* gas pressure;
* environmental regulation;
* maintenance capability;
* energy price volatility.
There is no universally superior choice.
The correct answer depends on the factory location and operating economics.
