Performance improvement of biomass combustion-basedstove byimplementing internally air-distribution

Abstract

This research aimed to enhance the performance of biomass combustion-based stove. Thermal performances were assessed in terms of power output (Pout), specific fuel consumption (SFC), thermal efficiency (ηth), and burning rate (BR). These performances were expected to meet the minimum standards established by the Indonesian biomass stove alliance regarding the use of a healthy and energy-saving of biomass stove in Indonesia. The stove tested was an improved stove with an advantage on the air distributor by adding a component to administrate air combustion needed placed on the centre of the combustion zones. This is a very effective way to distribute air for combustion required where the air could reach all the fuel and the combustion product that occupy entire the combustion zones to ensure high combustion zone temperature. Coconut shell was used as feedstock. This biomass was found abundant in Indonesia and was widely used as heat source by burning it directly. The coconut shell was sized uniformly about 5 cm x 5 cm, dried by utilizing sun energy. To estimate the stove performances, several combustion tests was carried out where the air flow rate into the stove (Qa) and the amount of biomass fuel (mb) referred as the air–fuel ratio (A/F) were considered. The Water Boiling Test (WBT) was performed to assess this improved stove. Parameter required such as initial mass of coconut shell, the mass of residual ash, the initial mass of water, mass of water after boiling, and the time required to boil as well as combustion flame temperature were recorded and used to determine the performance of the improved stove studied.

Technical Parameters Study of Coconut Shell Combustion as Heat Source by Using Fixed-bed Type Incinerator

“…The higher the ER, the higher the burning rate, means that more fuel is consumed. This finding is in accordance with what was found by Simanjuntak et al [24]. However, the high burning rate does not determine high temperatures of gas products.…”

“…By regulating the distribution of air in a wood-burning stove, Sornek, et al [22] and Carvalho et al [23] are also succeed in reducing greenhouse gas emissions. By placing an air distributor concentrically in a cylindrical biomass combustor, Simanjuntak, et al found that the temperature of the flame reach of about 550 o C [24]. Caposciutti et al [25] also studied fixed-bed combustor for commercial scale boiler by varying excess air to control the temperature.…”

Potential of Pyrolytic Oil from Plastic Waste as an Alternative Fuel Through Thermal Cracking in Indonesia: A Mini Review to Fill the Gap of the Future Research

“…In addition, the fluidized bed reactor can be scaled to an industrial scale [38]. Whereas, the packed bed reactor also has high performance when the hydrodynamic flow of combustion air is made more evenly distributed [39][40]. In pyrolysis, there are three heating methods that are always used by researchers; the fast, medium, and slow heating methods.…”

Experimental Study of Used Lubricant Oil Combustion as an Alternative Energy Source

“…Stove technology refers to the use of specialized stoves or furnaces to safely and efficiently combust waste materials. The number of stoves that have been tested related to their function intended to collect and collate information about performances and their output in the form of energy and emission parameters [7], [8]. This technology aims to minimize the environmental and health risks associated with especially hazardous waste energy recovery.…”
