## Abstract

Boiler is a closed vessel where the heat of combustion is transferred to the water until it forms hot

steam or steam. The boiler used in the PT ANTAM PLTU is a CFB type, where the operator at the PLTU ANTAM

Tbk performs heating value input to determine the amount of coal and combustion air used. The analysis of the

effect of the input heating value is expected to be taken into consideration in knowing the effect of the heating

value input which is different from the heating value of coal supplied to the furnace, which is viewed from the side

of pressure and temperature, which affects the physical boiler, boiler work efficiency, heat losses in the boiler.

and also boiler life time. From the results of research and analysis of efficiency calculations where there is the

largest difference in the value of efficiency directly at 1.161935% at the start of operation and 1.20276% in

March 2020 between calculations with GCV of coal and input of heating value. Meanwhile, the largest difference

in efficiency was indirectly 0.085689% at the start of operation and 0.09224% in March 2020. Meanwhile, the

largest difference in total heat losses at the beginning of operation was 0.09245% and in March 2020 was

0.69317%.

Key words: Boiler, CFB, Calorific value input, Efficiency.
