Discussion on heating methods for hangars and engineering case analysis

Summarizes five kinds of heating methods adopted in maintenance halls of hangars and analyses the advantages and disadvantages of various heating systems. Compares their initial investments and operation costs. Taking examples from engineering practice, puts forward the suitable heating system for the large space of hangar and summarizes several aspects requiring attention in designing gas-fired infrared radiation heating system, providing reference to heating system design of the maintenance hall of hangars.
