摘要

One of the thermal transmission rates that represent thermal transmission from gas to steam in a heat exchanger constituting a boiler is calculated based on thermal conductivity rate of pipes and thermal transfer of steam and gas, and the other is compared with the thermal conductivity rate calculated based on the thermal conductivity rate of the pipes and thermal transfer rate of steam and gas.
