Structural types of high-power gas-fired heat transfer oil furnaces
Thread Content
As the title suggests, what type of structure is generally used for high-power gas-fired heat transfer oil heaters, such as those with 7 million BTU or 8 million BTU capacity? In my opinion, the thermal efficiency of coil-type tubes is low. Are coil-type radiators useful?
With different structural patterns, the heat transfer during calculation must also be different, right? I’m only half-competent, so I wanted to find someone who’s fully skilled to ask for advice from. I would appreciate your guidance.
Square coiled tube? Heat transfer oil furnaces generally have a spiral coiled tube structure, similar to a spring.
