Operating principle of Heating X-L Pipe
Nucleate boiling and film boiling that occur when heating in a closed space
– Nucleate Boiling
Nucleate boiling is a phenomenon where air bubbles occur independently from fine air bubble nuclei at the side of heat transfer by beginning from the temperature slightly above the saturation temperature when heating liquid for boiling. When the temperature at the side of heat transfer rises, occurrence of air bubble and mixing of breakaways increase, greatly increasing heat transfer coefficient to maximize energy saving and efficiency.
– Film Boiling
Film boiling is a phenomenon where steam bubbles occur on the entire heating side in the shape of the side when heating a liquid for boiling.
It occurs when the heating capacity is very high. When heating in a closed space, film boiling leads to heat storage effect from insulation effect of gas (depends on temperature but approximately 0.0347 kcal/mh℃) in the heating plate that has been heated for a certain period of time. The heat energy (Kcal) generated during this process maintains the certain temperature for longer time due to heat storage effect of internal gas, contributing to saving energy.
