Within the U.S., fuel-based process heating (excluding electricity and steam generation) currently accounts for 5.2 quads (quadrillion British thermal units), which equals roughly 17% of the total industrial energy use. Typically, the energy used for process heating accounts for 2% to 15% of the total production cost. Savings of 20% or more are typically achievable through systems optimization. To address this opportunity, the Industrial Heating Equipment Association (IHEA), a US process heating equipment manufacturers association, and the DOE have collaborated on numerous projects. On behalf of US DOE, Berkeley Lab has worked with IHEA and its member companies to increase awareness in US industry of the benefits of applying system optimization techniques.
