What is one design parameter for oil-fired furnaces?

Oil-fired furnaces must be designed with careful consideration of furnace wall temperatures to ensure safety and efficiency during operation. High temperatures can lead to structural damage or failure of the furnace walls, ultimately compromising the integrity of the system and potentially leading to hazardous situations. Keeping furnace wall temperatures within an optimal range prevents thermal expansion issues, warping, and degradation of materials, and helps maintain efficient heat transfer. Proper insulation and design strategies can help manage these temperatures, ensuring that the furnace operates effectively without risking damage or unsafe conditions.

While the other design parameters are also important considerations for oil-fired furnaces, controlling the furnace wall temperatures is crucial in preventing technical failures and ensuring operational longevity.
