Efficiency solutions for biomass boiler plants

The incorporation of a second stage flue gas condenser, combined with an absorption heat pump, presents a highly efficient solution for the recovery of low-temperature potential heat. This technology stands apart from compressor heat pumps in that its driving force is not electricity, but rather heat with a high-temperature potential.


By using this innovative equipment, the overall efficiency of existing boiler plants is significantly increased, resulting in more efficient fuel consumption, reduced CO2 emissions, and lower thermal energy costs for consumers.

Absorption heat pump.jpg

Absorption heat pump

The absorption heat pump is used for continuous
cooling of liquids such as flue gas condensate.
The absorption heat pump requires:
/ Hot process fluid (water or steam) at a temperature
of at least 110 °C, in some cases up to 80 °C, such
as hot boiler water or steam.
/ Warm process water up to 50 °C, for example,
return district heating water.


IMPORTANT: the technology must contain a
medium with a low-temperature energy potential,
such as flue gas
.

Second stage flue gas condenser

Our equipment is designed to recover residual heat by efficiently cooling biomass combustion products, also known as flue gas, to a temperature range of 22-35°C. The key differentiator of our system is its solid construction, achieved through the use of Glass Fiber Reinforced Plastic (GRP) molding technology, which ensures durability and reliability for long-term use.

Our second stage flue gas condenser effectively utilizes condensate to cool the flue gas, which is then constantly cooled in an absorption heat pump. This enables us to recover heat from the condensate and transfer it to heat networks, further enhancing the efficiency and effectiveness of the overall system.

For thermal inputs up to 3 MW, we offer a GRP composite flue gas condensing economizer, which is both cost-effective and highly efficient. In addition, for higher capacity requirements, we also provide a vertical flue gas condenser, with maximum thermal input tailored to meet the unique needs and technological possibilities of each individual customer.

Heat recovery cycle

The absorption heat pump consists of an evaporator, an absorber, a condenser, a generator, a solution
heat exchanger, an absorber heat exchanger, a coolant/solution pump, a purge pump and control
equipment. The operation of the absorption heat pump is initiated by starting to supply a high temperature
fluid (e.g., heating water from the boiler or steam) to the generator circuit. At that time, the thermal energy
of the low-temperature condensate accumulated in the evaporator circuit; in the second stage flue gas condenser evaporates the operating fluid. The total thermal energy supplied from the generator circuit and obtained in the evaporator circuit is transferred to the heating water or other
process fluid in the absorber and condenser circuits.

For the cooling process to occur continuously, the generated steam in the evaporator circuit must be
removed. A solution of lithium bromide in the absorber circuit is used to absorb these liquid vapors.
During this process, lithium bromide is diluted, resulting in a decrease in its absorption capacity. The
pumps transfer this solution to a generator where the hot water/steam flowing in the circuit heats the
diluted lithium bromide solution and reaches the boiling point. The boiling of the coolant increases the
concentration of lithium bromide. The coolant vapor emitted on the generator circuit side enters the
condenser, where it returns to the liquid state when cooled. The coolant returns to the evaporator and
begins a new cycle.
