Abstract
Biomass attracts a great deal of attention to be converted into green fuels in the form of pellets. The furnace is needed to burn pellets to generate heat up to 300 kW. In addition to meeting the heat capacity needs of the small and medium-sized industries, furnaces must also be competitive in terms of price. The purpose of this study is therefore to obtain details of the cost of manufacturing the furnace and the model of air flow that occurs in the furnace. The cost of production of the furnace includes manufacturing costs, assembly costs, machining and repair costs. The findings revealed that the key portion of the cost of the furnace was a material cost of 77%. The findings of the simulation showed that the total pressure difference of up to 850 Pa and had to be resolved by air-supplying blowers. The gas velocity ranges from 2 to 10 m/s and rises significantly near the exit to 42 m/s.

The use of fossil fuels as an energy source has adversely affected the cleanliness of the environment through exhaust emissions
Summary
The use of fossil fuels as an energy source has adversely affected the cleanliness of the environment through exhaust emissions. The limited supply of fossil fuels [1] has sparked the growth of renewable energy technology and the quest for alternative energy sources, such as biomass. Biomass content continues to be renewed as long as the ecosystem in which it is preserved and can be used as a renewable source of energy production [2]. Kaliandra woods have a strong growth, sturdy, specific gravity of 0.5-0.8, easy to dry, easy to burn, and calorific value of 4200 kcal/kg [3]. Kaliandra wood biomass pellets have a higher density [4]
