Innovations Item Code: IN-2024-2100577
Sector: Renewable/Green Energy
Description:
This design introduces a thermal converter that extract and utilizes the heat from the flue gas to preheat the feed water and dry the biomass feedstock.
The design also incorporate a retrofit for particulate emission reduction. This will lower the discharge of harmful gases to the environment to a safe level.
The design also consider the use a wide range of biomass for the feed stock. This will help analyse the impacts of the different biomass feedstocks on the boiler efficiency.
Stage of Innovation: Proof of Concept (You have created something to show the innovation can work)
Problem:
Heat loss through the biomass boiler exhaust and the particulate emission through the exhaust zone have not been adequately utilized and this could have significant effect on the performance and efficiency of the biomass boiler.
Likewise, the particulate emission are a combination of nitrides, carbon monoxides, smoke and other gaseous substance which may be harmful to environment. It is necessary to reduce the flue gas to a safe level that is harmless to the environment.
Most studies primarily focuses on specific biomass feedstocks for boilers, overlooking the broader range of variety of biomass feedstocks and their impact on boiler performance.
This study intends to address the problems above by incorporating a thermal converter, a retrofit for particulate emission reduction and adaptation for variety of biomass feedstocks.
This innovation will enhance the thermal storage and efficiency of the boiler, reduce the biomass consumption and reduce the discharge of particulate emission to the environment.
Unique Selling Point: Studies such as Hebenstreit et al. (2014) and Pachaiyappan and Prakash (2015) have investigated flue gas heat recovery. Studies such as Bianchini et al. (2017), Xiaosong et al. (2021), and Cornette et al. (2021) have investigated the reduction of emission particulates in the boiler but did not consider harnessing the heat loss through the exhausts and the emission gas for boiler efficiency. Most studies did not consider a combination heat recovery and emission reduction. This design incorporates the combination of heat recovery using a thermal converter, emission reduction using a retrofit and adaptation to variety of biomass feedstock.
