Features

Specifications

Maximizes steam utilization by recovering excess low pressure steam at a higher pressure resulting in reduced energy costs and CO2 emissions.1. Reuses energy from excess steam by increasing it

to low/medium pressure.2. No electricity required, so suitable for explosion-

proof areas (with COS pressure control valve).3. Condensate recovery tank unnecessary with

optional condensate recovery package: condensate is first reduced to atmospheric pressure, then repressurized to mid-pressure steam for reuse.

4. Employs a new, independently-designed high efficiency ejector.

5. Pressure control valve has a built-in separator and steam trap, maintaining dry motive steam, thereby ensuring high long-term efficiency and stable discharge pressure.

To avoid abnormal operation, accidents or serious injury, DO NOT use this product outside of the specification range. Local regulations may restrict the use of this product to below the conditions quoted.

● Capacity Check (Motive Steam Quantity and Discharge Steam Quantity)

At 0.9 MPaG motive steam pressure, according to Performance Graph ①, the entrainment ratio is approximately 3.9*. The motive steam quantity and discharge steam quantity can be calculated using the formulas A) and B) below.*Entrainment Ratio = Motive Steam Quantity (kg/h) / Suction Steam Quantity (kg/h)

Sample Calculation (For motive steam pressure of 1.0 MPaG)At 0.9 MPaG motive steam pressure, according to Performance Graph ①, the entrainment ratio is approximately 3.9. At 1.2 MPaGmotive steam pressure, according to Performance Graph ②,the entrainment ratio is approximately 2.8.The calculation in C) gives an approximate entrainment ratio of 3.5.

If motive steam pressure is between those given in Performance Graphs ① - ③, calculate using the higher and lower pressure graphs and estimate using the mean entrainment ratio.

B) Discharge steam quantity = Motive steam quantity + Suction steam quantity = 1170 kg/h + 300 kg/h= 1470 kg/h

A) Motive steam quantity = Entrainment ratio Suction steam quantity= 3.9 300 kg/h= 1170 kg/h

(3.9 - 2.8) = 3.5 - (1.0 - 0.9 MPaG)

(1.2 - 0.9 MPaG)3.9

C) Sample Calculation (For motive steam pressure of 1.0 MPaG)

NOTE: If using COS control valve (SC1-1, SC2-1, SC7-1), the Discharge Steam Pressure range is restricted to between 0.1 - 0.3 MPaG. The type-selection and capacity values from the above procedures are only approximations. Contact TLV for actual selection and performance data.

Using Model Selection Graph ① for 0.9 MPaG motive steam pressure, point A represents the sample suction steam pressure and capacity conditions for the desired discharge steam pressure (P3) of 0.3 MPaG.

In the 0.3 MPaG discharge steam pressure range, point A falls slightly below the SC2 line, therefore Model SC2 or SC7 should be chosen.
