Rice straw could be used for heat and power with the current technologies available in Thailand. The cost of rice straw for power generation at 0.38-0.61 Baht/MJ(e) (at rice straw price 930-1500 Baht/t) is not competitive with coal at 0.30 Baht/MJ(e) but comparable with other biomass at 0.35-0.53 Baht/MJ(e). However. utilization of rice straw in industrial boilers is a more competitive and flexible option with two alternatives; (1) installing rice straw fired boilers instead of heavy oil fired or natural gas ones when selecting new boilers: and (2) fuel switching from coal to rice straw for existing boilers with cost saving of feed-stock supply by 0.01 Baht/MJ(h). Based on its properties (Slagging index, R-s = 0.04; fouling index, R-f = 0.24). rice straw is not expected to have significant operating problems or different emissions compared with wheat straw and rice husk under similar operating conditions.
