How do you size steam traps?
A large number of steam users improperly select trap size based on the size of existing piping. However, trap size should closely match the size of the piping on the outlet side of the equipment that supplies condensate to the trap. 15 mm [1/2 in.]
What is PMX in steam trap?
obtained by operating the trap below its specified maximum operating pressure (PMO) and maximum differential pres- sure (PMX).
What is PMA and PMO?
Financial Management Funding for Program Management Administration (PMA) is the cost of mission essential office operations in direct support of a program and its program management office (PMO). It’s budgeted on an annual basis and reflected in the fiscal year during which the requirement is projected to execute.
What is the MOC of steam trap body?
Body Material The materials used for the steam trap body, cover, and other pressure-resistant parts are no different from those used in other types of valves. Some examples are: Gray Cast Iron/ Ductile Cast Iron. Carbon Steel. Stainless Steel.
How is steam load calculated?
The feedwater flow rate can be calculated from steam mass flow and blowdown rate:
- Blowdown Mass Flow = Feedwater Mass Flow * Blowdown Rate.
- Steam Mass Flow = Feedwater Mass Flow – Blowdown Mass Flow.
- Steam Mass Flow = Feedwater Mass Flow – Feedwater Mass Flow * Blowdown Rate.
How is condensate rate calculated?
Calculate the total condensed liquid flow based on the heat load from the process reactor. This is determined by dividing the total heat removed by the system by the latent heat contained in the steam. The calculation is 30,000 / 794, which is 37.8 lb/hr of liquid condensate.
How is steam leakage calculated?
Steam Loss = 22.88 x Pa x D2 Steam flow through a leak can be calculated using a the above orifice equation, which is based on the diameter of the leak, the pressure at the inlet of the orifice, and the pressure at the outlet (atmosphere).
What is SLR in steam trap?
This trap is provided with two optional features called Steam Lock release (SLR) and Thermostatic Vent (TV). The SLR is a manual operation to release steam that may hamper free movement of the float on water level.
What are the types of steam trap?
Three Categories of Steam Trap Based on Operation Principles. Mechanical Steam Traps. Thermodynamic Steam Traps. Thermostatic Steam Traps.
What is PMA DOD?
Funding for Program Management Administration (PMA) is the cost of mission essential office operations in direct support of a program and its program management office (PMO).
