Pressure Reducing Valve (PRV) Stations
Pressure reduction stations are required to regulate the high incoming pipeline pressure to meet the desired equipment pressure. Steam pressure reducing valves are used in commercial, industrial, and institutional applications to regulate steam pressure. Steam enters the PRV station at a higher pressure than what is required for downstream applications, and the station reduces the pressure to the desired level before delivering steam to those applications.
Blanket Insulation for Pressure Reducing Valve (PRV) Stations is the effective way to reduce heat loss and improve energy efficiency in your steam boiler system.
PRV Stations – the case for Thermal Blanket Insulation Systems
PRV stations have complex geometry along with need for access for adjustment and repair.
Because of this fact many PRVs, piping, joints and flanges are left uninsulated or partially insulated. The other issue involves poorly done site fabrication of insulation with materials not suited for the condition or longevity. Or conventional insulation removed & destroyed in the process of removal for access to equipment.
At times of necessary access, it becomes challenging and complicated, to remove the conventional insulation to access the surfaces for inspection, service or repair. This type of insulation would be discarded, as it is not reusable. Keep in mind, these hot surfaces are often left uninsulated because of this, generating unnecessary heat loss. When this occurs the original insulation investment is rendered useless.
insulating with Removable reusable Blanket Insulation – ROI
A PRV Station is typically a 1/3, 2/3 reduction, giving you a series of duplicate complex surfaces. The system is typically made up of 2 each gate valves, a strainer and a PRV, all times 2 (1/3 +. 2/3). That plus a by-pass globe valve.
So its a total of 9 fittings untreated.
To insulate with SGES Blanket Insulation, that’s 9 x $300 (approx. cost per fitting) = $2,700 approx. cost to insulate, and roughly $1,300 in annual energy savings. You could realize savings of $1,300 per year for 15 years. What other investment delivers that type of ROI?.
By the way, there are utility credits offered that in some cases will give you an 85% rebate on the $2,700.00, so the opportunity is even more impressive!!! Now imagine a system approach and capturing 200-500 fittings!
