Reduction of CO_2 emissions and energy saving are the urgent issues for many fields of industries at present. Steam, occupying considerable energy consumption rate in the whole industry, is generally generated at boilers. The boiler efficiency was generally thought to be approximately ninety percent. However, rate of heat loss from steam pipes can not be neglected on occasions. Accordingly, we executed measurement of total boiler efficiency considering heat loss from steam pipes in an operating factory. Two methods were employed for the measurement of heat loss from steam pipes. One is how deference is calculated between steam flow rate at boiler exit and that at machinery using steam. The other is how each drain flow rate from drain-trap is measured. Both results are compared and discussed.
