This paper presents an integrated performance evaluation of in-lab manufacturing own designed prototype biomass fired-stove used coconut shell as feedstock. Two different stoves in terms of air required for combustion supply mode;(1) external air box (EAB), (2) internal air box (IAB) mode were tested and assessed with respect to the following performance indicator such as water time to boil, specific fuel consumption, and thermal efficiency. The stoves tested were the forced draft modified rocket-stove types with a battery mini fan-assisted to induce draft to force the controlled air for combustion requirement into the stoves. Flame temperature wasrecorded and displayed using K-type thermocouple and thermometer indicator respectively. Specific calculated using the water boiling test (WBT 4.2.3) version protocol. Results showed that the internal air box (IAB) mode has higher thermal efficiency (38 %), specific fuel consumption (2.5 kg/h), and flame temperature (500 0C) than external air box (EAB) mode. However, the thermal output of the EAB (2.3 kW) was reached higher compare to IAB mode. The findings were used to improve the current biomass fired-stoves further that usually used for heating and cooking applications in rural communities.

“…Some researchers studies on residence time for solid particles with positron emission particle tracking (PEPT) method inside the riser section by using Geldart B-type bed material. They have used different riser size such that 0.046, 0.09, 0.16 m ID with 4 m riser height [40]. Tracer technique is also a newly developed way to estimate the solid residence time distribution inside riser section.…”

In this paper a brief review on hydrodynamic characteristic of coal gasification is presented. Firstly an introduction of hydrodynamics then parameters related to hydrodynamics is discussed. In the last several decades Coal gasification is an important method to use of coal resources. The hydrodynamic characteristics have an important role to design of Circulating fluidized bed gasifiers. Circulating fluidized bed (CFB) gasifiers widely use due to their high reaction rates and high thermal efficiency. The present study includes some hydrodynamics properties of coal gasification such as effect of pressure and temperature, solid hold up, solid circulation rate, gas-solid contact, particle residency time, coal feeding rate and coal feeding position. During the brief review on hydrodynamics characteristics of coal each section of CFBs such as riser, cyclone, stand-pipe and loop seal have been considered.

Biomass gasification based power plants can play an important role in power sector in Malaysia with her abundant agricultural and forest resources. In this research energy and economic feasibility, and environmental impact of biomass gasification power plant has been analyzed and assessed for sustainable power generation in Malaysia, the plant being a clean development mechanism supported project. Gasification based power generation with a dual fuel internal combustion engine is found more biomass combustion power plant. But, the annual fuel cost is significantly higher with gasification plant claiming MYR 10 million/y for a generation of 67,500 MWh. The net present value, internal rate of return, and PBP for a 10-MW gasification based dual fuel internal combustion engine power plant without loan financing using empty fruit bunch pellet as biomass; with CER issued at USD16/tCO2; and without loan financing provides net present value, internal rate of return, and PBP of MYR 19.68 million, 11.90%, and 6.05 y, respectively. With a loan financing at 3% per year with CER still be effective the net present value, internal rate of return, and PBP is estimated to be MYR 7.03 million, 3.97%, and 11.78 y, respectively. However, if a 60:40 debt equity is applied then the project net present value, internal rate of return, and payback period seen to improve slightly. The net present value attains a positive value of MYR 3.6 million. Internal rate of return and PBP values are found to be 7.08% and 8.27 y, respectively. The emission reduction achieved with the plant is 17,863 t CO2/y, 206 t SO2/y, 90 t NOx/y, and 10.37 t CO/y, respectively. Energy efficiency and tariff policy have been found to have highest impact on economic profitability of gasification based power generation units.
