Reducing the Starting-time of Boilers and Turbines
regulate -the starts by the thermal conditions of the
turbine rather than by a fixed time-table. According to
the 1956 manufacturers' instructions the time required to
start and put on load a turbine VK-100-2 was already cut
to 9' hours. Recent recommendations have cul- this time
V V
by a further two hours, and the resent conditions will be
seen from the tirae chart in Fi.f,, ~. During 1957, tests
were made on starting turbines in the Moscow power system
whilst steam was being ralsed in the boilers. The circuits
used to isolate a boiler-turbine unit are given in
Figs 6 and 7. In other tests the turbine was started with
steam of reduced temperature and pressure, derived from the
normal steam mains. It was found possible to cut the
turbine starting times to about half of the former values.
Details are given of the starting times r,3quired after the
turbine had been standing for various periods. It is
particularly difficult to start a boiler-turbine set as a
unit after standing 5 - 7 hours overnight, because the
turbine and boiler cool at different rates. The risk of
Card 5/6 passing cold steam into a hot turbine can be overcome by
first raising the temperature and prossur:) in the boiler

Reducing the Starting-time of Boilero and Turbinos
somewhat. Unit starts with reduced steam conditions are
now becoming fairly corm.,ton. In making accelerated starts
the condition of the thermal insulation on the turbine is
very important. It should be possible to reduco still
further tae tii.ie required to start u-1) boilers and turbines.
