Review of small steam turbines (0.25-10 MW{sub e})

Miscellaneous:

Abstract

In view of growing interest in the recovery of energy which might otherwise be wasted, a survey was undertaken in 1987/88 to obtain basic information on small steam turbines of 2-10 MWe output covering manufacturers in the UK, Europe and the United States. The survey was subsequently extended in 1988 to include back pressure turbines with an output between 0.25 and 2 MWe. Information was sought on steam consumption and likely capital cost for turbines suitable over a limited range of steam conditions. For turbines with outputs between 2 and 10 MWe there was a reasonable consistency in steam consumption between equipment from the various manufacturers for any given size of turbine. The most efficient required only 2-3% less steam than the average for any given output. For turbines between 0.25 and 2 MWe there were greater variations between manufacturers in steam consumption. Turbines supplied by one maker were the most economical in steam range at 40 bar pressure but the least economical at 20 bar. In the range, variations of 25% from the average were not uncommon. Price variations were substantial. The least complex equipment in the range of larger machines was, in almost every case, the least efficient  More>>

Price variations were substantial. The least complex equipment in the range of larger machines was, in almost every case, the least efficient (which might be expected) but, surprisingly, appeared to be significantly more costly than more sophisticated equipment from elsewhere. Cost information for all turbines was generalised against a small range of equipment sizes and steam conditions. The tables and diagrams within the report give and indication of relative costs for different sizes and steam conditions obtaining at the time of the survey. (author).}
