Measures for the efficiency increase
Air preheaters, waste heat recovery systems
Fired heaters vs Electric heaters
Advantages of fired heaters against electric heaters:
High heating capacity at low operating costs, high efficiency in combination with waste gas treatment and combustion air preheating (efficiency > 90 %)
Disadvantages of fired heaters against electric heaters:
More complex installations (chimney, boiler house), thus normally higher initial investments, more maintenance-intensive
