- Ball Float type Steam Trap
- Inverted Bucket type Steam Trap
b) Thermostatic Steam Traps are mainly used for condensate draining of Tracing Steam line (Process fluid line tracing, Instrument tracing).
c) Mechanical type Steam Traps are mainly used for condensate draining from Indirect Steam Heating Equipments (Heat Exchanger, Reboiler,
Jacketed Vessel, Storage Tank).
b) In Process industries steam is used in indirect as well as direct heating application.
c) Maintaining the temp of hot process fluid during transferring from one place to another by using steam tracing line.Steam tracing also used for many instruments in industries.
d) Steam also being used as a coolant in Hot Oil Pumps in Chemical, Petrochemicals Industries, Petroleum Oil Refineries.
e) Steam also being used in Steam Ejector.
f) Steam also being used as utility and in application like Shoot Blowing media for Burners in Furnace, flushing of lines etc.
ii) 1% fuel saving can be achieved by increasing Boiler Feed Water temp by 6OC.
iii) High temp Feed Water injection in steam drum will avoid thermal shock.
b) Increasing Boiler Feed Water Temp by recovering heat from Flue Gas using Economizer.
c) Increasing Boiler Feed Water Temp by mixing live steam with feed water in feed water tank / de-aerator tank.
d) Increasing Boiler Feed Water Temp by recovering heat from blow down water – directly mixing Flash Steam of blow down water with feed water or indirect heating.
i.) Latent heat available (qty of heat will release on condensation of steam) is higher at lower pressure. So at low pressure steam consumption
in process is low. Steam to be used at lowest practically possible pressure depending upon maximum temp to be achieved in process.
ii.) Specific volume of steam is higher at lower pressure & lower at higher pressure. So,
a) Generation of steam at high pressure require less volume of Boiler, hence less investment, less space requirement.
b) Transfer of steam at high pressure from one place to another pipe size requirement is less, weight & cost of piping will be less.
c) Transfer of steam at high pressure from one place to another, due to lower pipe size, support for piping & requirement piping equipments will be less.
d) Transfer of steam at high pressure from one place to another, due to lower pipe size, insulation materials will be less.
e) Transfer of steam at high pressure from one place to another, due to lower pipe size & outer surface area, heat loss to ambient will be less.
iii.) Steam using in industries at different pressures. Generation of steam at different pr require different boilers are not feasible. So generating steam at higher pressure at boiler and reduce steam pressure, near the point of uses, to the needed low pressure.
