Effect of Sawdust Particle Size on Physical, Mechanical, and Energetic Properties of Pinus durangensis Briquettes

Abstract

Particle size is a physical property that sometimes limits the quality of briquettes, so it is recommended to use different sizes in mixtures for their manufacture. The objective of this research was to evaluate the effect of different particle sizes of sawdust in mixtures on some physical, mechanical, and energetic properties of briquettes made from Pinus durangensis sawdust, as well as set the ranges within the appropriate values found to obtain desired values. Three particle sizes were established (large, medium, and small), and 10 mixtures were prepared using different percentages of each particle classification. The particle density, volumetric swelling, compressive strength, impact resistance index (IRI), and gross calorific value of the briquettes were evaluated. For the determination of optimal mixtures, the surface response methodology was used under a three-factor simplex-lattice model. The particle density values were in the range 0.92 to 1.02 g cm−3 and the volumetric swelling was 0.96 to 3.9%. The highest resistance to compression was 37.01 N mm−1, and the IRI was found in the range of 53 to 107%. The gross calorific values were from 19.35 to 21.63 MJ kg−1. The selection of different particle sizes for the mixtures increases the quality of the briquettes.

Physicochemical Characteristics of Biofuel Briquettes Made from Pecan (Carya illinoensis) Pericarp Wastes of Different Particle Sizes

“…A vertical orientation laboratory briquetting machine (LIPPEL ® , Agrolândia, Santa Catarina, Brazil) was used, which presents a solid base with a cylinder of 20 mm in diameter and an integrated thermostat that allows the temperature to be modified, two pistons that apply pressure and facilitate the briquette extraction. Each one was made with 200 cm 3 of the base material, and the operating conditions were 15 MPa of pressure, 90 °C of temperatures and five minutes pressure, similar to that developed by Zepeda-Cepeda [ 53 ] and Ramírez-Ramírez [ 54 ], for briquettes of 3.3 cm in diameter and 8.0 cm in length. Eight briquettes were made per treatment (granulometry) for subsequent analyzes.…”

Reuse of Sawdust in Developing Countries in the Light of Sustainable Development Goals

“…According to the regression models, species density, particle size, and compacting pressure were good predictors of relaxed density and compressive strength in the cleft of briquettes made from sawdust of tropical hardwood. Zepeda-Cepeda et al [89] studied the impacts of different sawdust particle sizes in mixes on some physical, mechanical, and energy properties of briquettes derived from Pinus duranguense sawdust, as well as established the ranges within the appropriate values determined to reach desired values. The surface response approach was utilized to determine optimum combinations under a three-factor simplex-lattice model.…”

Utilization of solid residue from hydrothermal liquefaction of breadfruit pulp for the production of bio-briquette using cassava starch as binder

“…These include; the use of rice husk and the combination of rice husk and other agro waste such as wheat straw, and maize stalk ([ 12 ]; [ 7 , 13 ]. Some other researcher used sawdust of different woods and the combination of saw dust and other agro-waste for briquette production [ 9 , [11] , [13] , [14] , [15] , [16] ]. While other work such as Niedziółka et al [ 17 , 18 ] reported the use of other agro-waste such as rape and oat straw, maize straw and cobs, and its mixture for briquette production.…”
