A typical coal fired power plant has a boiler efficiency of approximately 90 percent. For each 100 Btu's (106 kj's) of fuel into the plant, approximately 10 Btu's (11 kj's) flow out as boiler and stack losses and the remaining 90 (95 kj's) are transferred to. steam flowing to the turbine cycle.

The issues discussed above lead to supercritical boiler technology being given a reputation of having limited operating capability, complex maintenance issues, lower availability, and lower plant efficiency than expected. As a result, the trend in boiler type moved towards subcritical drum type boilers during the 1970s. 4.

Boiler yang konstruksinya terdiri dari pipa-pipa berisi air disebut dengan water tube boiler (boiler pipa air). Pada unit pembangkit, boiler juga biasa disebut dengan steam generator (pembangkit uap) mengingat arti kata boiler hanya pendidih, sementara pada kenyataannya dari boiler dihasilkan uap superheat bertekanan tinggi.

for a given boiler is to conduct a combustion test at different pressures and constant load. Figure 2 shows the relationship between pressure and stack temperature for a test on a 65,000 lb/hr watertube boiler operating at a constant output of 38,500 lb/hr. As tested, the boiler stack temperature varies linearly with steam pressure.
