Davydovka and Osobino Cogeneration Units: Two Thermax Absorption Chillers in Belarus

At two gas-fired cogeneration (CHP) units in Gomel Region, Davydovka and Osobino, Thermax lithium bromide absorption chillers are in operation: an LT 14C of 651 kW and an LT 10C of 280 kW. Both run on hot water from the waste heat of gas engine generator sets. We supplied the machines, carried out installation supervision and commissioning, and trained the staff.

What was the task?

The engineering logic is this: at plants where gas goes into engines, part of the heat is free in summer, and it is turned into cooling for air conditioning. The capacities are small, 651 and 280 kW. At Osobino this is below the usual 300 kW threshold for an absorption chiller; such cases are calculated separately.

How does the scheme work?

The classic: gas engine and hot-water absorption chiller

Hot water from the gas engine sets drives a single-effect machine, which supplies water at 12/7 °C. The NCT cooling tower rejects the heat.

What was the result?

Start-up took place on time under the contract. The absorption chillers were delivered to Davydovka in October 2013 and to Osobino in May 2014. Both letters are signed by the contractor, not by the oil company itself.
