1 Brief project description of the biomass
Brief project description of the biomass multi fueled LAWI EtaPlant® Srisangdaw 9.9 MW with 45 tph steam boiler capacity at 66 bar(a) and 485°C Commissioning date: June 2012 Client: Srisangdaw Biopower Co., Ltd. Plant location: Roi Et, Thailand Srisangdaw 9.9 MW biomass power plant was designed by LAWI Engineer - ing for Srisangdaw Biopower Co., Ltd. and commissioned in the year 2012. This project is conceptualized as a fully condensing power plant to supply electric - ity to the public grid of the Provincial Electrical Authority (PEA). The total in - vestment for this project is around 25,000,000 USD. All works for it have been completed within initial project schedule under LAWI project management. This power plant is located in Roi Et Province in Thailand
2 and is connected to the lo - cal Srisan
and is connected to the lo - cal Srisangdaw rice mill. In order to provide flexibility and constant operation even in times when rice husk is unavailable or available only at increased prices, LAWI Engineering has integrated the LAWI EtaComb® multi-fuel combustion system into this project. It allows safe and reliable usage of not only rice husk, but also other available agricultural residuals, in particular residuals from the nearby bark industry. Srisangdaw power plant has made a significant contribution to improve northern Thailand’s decentralized power supply from renewable sources, saving Thailand 38,610,000 kg of CO 2 emissions per year. This project is as well supporting local economy of Srisangdaw by making use of different agricultural residua

with the conscious and professional operation management of the Srisangdaw team allowed to produce average gross power output of 67,000 MWh per year. This power out - put fully satisfies the design parameters and financial model for the project and therefore also the investor’s expectations. Since commissioning, Srisang - daw power plant proved to be operating on average 7,800 hours per year. The heart of this power plant is LAWI EtaComb® an advanced combustion technology, which is significantly responsible for the overall power plant performance in terms of efficiency and flexibility. This combustion system is combined with ERK waste heat boiler- its design allows to reach boiler thermal efficiency of over 90 %. This power plant operates with a very l
5 ow excess air rate with oxygen content
ow excess air rate with oxygen content of 3 - 4 %, resulting in combustion thermal efficiency over 98 %, because of low CO emissions and unburned hydrocarbons. An advanced emission control is reached through the electrostatic precipitator; these values fully meet emis - sion regulation in Thailand. In terms of overall electric efficiency, it is possible to reach average gross electrical efficiency of 27 % during current years of operation.
