Separating Throttling Calorimeter Manufacturer,Supplier and Exporter in India
Product Code : EL-TL-10061
Jlab Export is a leading Separating Throttling Calorimeter Manufacturer,and suppliers in India
Separating Throttling Calorimeter (code EL-TL-10061) is a combined steam calorimeter for finding the dryness fraction of wet steam. Steam from a generator at the base, controlled by a thermostat knob on the front, passes first through a separating calorimeter and then through a throttling calorimeter, after which a heat exchanger condenses it for collection. The calorimeter, steam generator included, is made by JLab in Ambala, India.

Why One Calorimeter Is Not Enough
A throttling calorimeter works only if the steam comes out of the throat superheated, or at least dry saturated. Throttling keeps the enthalpy constant, and saturated steam at the lower pressure needs less enthalpy, so slightly wet steam dries out and becomes superheated; very wet steam stays wet after expansion, and its thermometer then shows only the saturation temperature. A separator alone removes water mechanically, and never quite all of it. Putting the two in series covers both gaps: the separator takes out most of the water, and the throttling stage measures the little that remains.
From Readings to Dryness Fraction
Over one timed run, m is the water collected in the separator and M the condensate from the heat exchanger, giving x1 = M / (M + m). After the throat the manometer and thermometer fix the state of the superheated steam, and the steam table gives its enthalpy; setting this equal to hf + x2 hfg at the supply pressure gives x2. The supply steam has dryness fraction x = x1 × x2. Because the steam generator holds saturated steam, the temperature set on the thermostat also sets the supply pressure.
Other Steam and Calorimeter Equipment
- Separating and Throttling Calorimeter — the same two-stage method, read with a pressure gauge on the steam.
- Steam Power Plant Trainer — two-heater electric boiler feeding an engine or turbine and an alternator.
- Marcet Boiler — records steam pressure against temperature in a heated stainless steel boiler.
- Digital Bomb Calorimeter — calorific value of solid and liquid fuels, a different calorimeter type.
