Weiss has entered into a partnership with SEG A/S and can therefore offer retrofit solutions with SEGFlu® flue gas condensation for existing biomass plants.
With SEGFlu®, a larger share of the energy contained in the flue gas can be recovered and returned to the heat production process. The solution is suitable for, among others, straw- and wood chip-fired boilers and can be used with direct heat exchange or combined with an absorption heat pump for additional energy recovery.
More energy from biomass
The potential for heat recovery depends, among other factors, on the type of fuel and its moisture content. The figures below show examples of how flue gas condensation can affect efficiency and flue gas temperature:
| Straw 12 % moisture |
Straw 18 % moisture |
Wood chips 45 % moisture |
Wood chips 55 % moisture |
|
|---|---|---|---|---|
| Without flue gas condensation | 91,7 % | 91,5 % | 90,2 % | 89,1 % |
| Flue gas temperature | 140 °C | 140 °C | 140 °C | 140 °C |
| Direct heat exchange | 97,1 % | 98,2 % | 106,1 % | 112,5 % |
| Flue gas temperature | 50 °C | 50 °C | 50 °C | 50 °C |
| With absorption heat pump | 105,4 % | 106,7 % | 115,7 % | 122,9 % |
| Flue gas temperature | 25 °C | 25 °C | 25 °C | 25 °C |
Efficiency is stated in relation to the fuel’s lower heating value. The actual energy recovery depends on the individual plant, fuel and operating conditions.
SEGFlu BIO – condensate treatment
Flue gas condensation produces condensate, which must subsequently be treated. SEGFlu BIO is designed for the treatment of condensate from, among other applications, biomass boilers and waste incineration plants.
The system removes particles, impurities, heavy metals and PAH compounds while also regulating the pH level. SEGFlu BIO operates fully automatically, has a low chemical consumption and logs parameters including water volume, pH and temperature.
SEGFlu ULTRA – reuse of condensate
With SEGFlu ULTRA, the condensate can be treated further using ultrafiltration. The purified water can then be reused as make-up water in the plant instead of being discharged to the sewer.
This reduces the need for mains water and can also result in savings on both water consumption and wastewater discharge.
Retrofit for existing biomass plants
Through the partnership between Weiss and SEG, SEGFlu® can be offered as a retrofit solution for existing biomass plants. This makes it possible to improve energy recovery and reduce flue gas temperature without necessarily replacing the existing boiler plant.
