Crop residue burning is a common agriculture practice to eliminate post-harvest vegetative material, which hinders the seedling of the next crop. A prototype of a crop residue burning machine was developed and equipped with six LPG burners. The burners were designed as a forced-draft burner where the air was supplied by a blower/pump. While open field burning is a practical and economical practice for controlling insects, diseases, and weeds, the environmental risks of this activity are an issue. Open biomass burning is a major source of global air pollutants and has a major impact on global climate change. This study aimed to estimate the concentration of CO and NO x emitted from the combustion using this prototype. CO and NO x are important indirect greenhouse gases that affect the formation of tropospheric ozone or change the lifetime of methane. The air pollutants were measured using ECOM-EN2. The gas velocity, static pressure, and gas concentration were sampled with 1 minute’s average sampling time. Gas emission study shows a high concentration of O 2 in the flue gas. The recorded CO and NO x concentration exceeds the concentrations that regulated by EPA NAAQS. The average combustion efficiency of 98.0±0.3%, the highest emission factors for CO, NO, and NO 2 are 57, 3.7, and 0.5 lb/acre, respectively.
