Template assignment

Base case

• 65% efficient (including boiler flash, deaerator and blowdown losses) 1,200 kW natural gas steam boiler costing $90,000
• Equivalent full load hours of process heating: 5,250 h
• Natural gas rate is $0.30/m³

Proposed case

• 77% efficient (including losses due to heat distribution) 1,200 kW natural gas-fired thermal fluid heater costing $132,000
• Cost of heat distribution piping essentially the same as with steam boiler
• Every 6 years, thermal fluid must be replaced at a cost of around $20,000
