The separate heat and power system emits a total of 45 kilotons of CO 2 per year (13 kilotons from the boiler and 32 kilotons from the power plant), while the CHP system, with its higher efficiency, emits 23 kilotons of CO 2 per year.
All the factors which affect power plant performance, efficiency, reliability, safety and emissions will be explained thoroughly. All the areas in pulverized coal and circulating fluidized bed power plants where efficiency loss can occur will be explained. This seminar will also provide up-dated information in respect to the following topics:
And depending on the size of the steam plant, a considerable amount of energy loss is at risk if the boiler has faulty traps (see table below). Some larger plants may have 5,000 to 6,000 traps, while small plants may have 100 or less. However, no matter what size plant, a failed steam trap is not always obvious.
