and sprayed into the furnace by means of oil guns.
Sizing and selection of pumping and filter equipments, control and trip
devices, routing and location of piping, numbering and designation of
instruments are done manually to cater the heating capacity of steam
generators. This system of automation is developed by applying various
Technical rules, logics and standards to automate the above operations by
supplying minimal basic inputs. Unique numbering system also developed
for the identification of system components, equipments, instruments and
devices.
