In Sri-Lanka, two companies are involved in the design and manufacture of gasifiers. The leading company is EnerFab (Pvt) Ltd., which has recently been established and produces gasifiers for both thermal and electricity generation applications. In the case of electricity generation, the engines used are gas engines imported from China. The capacities of thermal gasifiers are in the range 100 kW to 350 kW. The efficiencies of these gasifiers are claimed to be in the range of 70 to 80% and the installation costs are in the range USD 200-300/kW. There are a few requests for installation of 5 MW range thermal gasifiers based on Indian technology. The capacities of the gasifier, designed by EnerFab (Pvt) Ltd, are in the range of 1 to 250 kWe. The overall efficiency of these plants are claimed to be around 30% and the installation costs are USD 800 to 1,500/kW. The other company involved with the design and fabrication of gasifiers is Puritas Ltd. The company has developed and constructed a 120-kW gasifier for brass melting industry under a project funded by UNDP (Bhattacharya and Abdul Salam, 2006).
