This research was conducted with the aim of developing a burnermodel BGO -30A for warming poultry farms using a mixture of used engine oil (UEO) with each of diesel and gasoline. This is to preserve the environment from pollution to reuse a cheap costly waste with no price for warming poultry farms, which reduces the cost of warming. A modified burner covers an area ranging from ​​30 to 50 m², suitable for as using the mixture containing (UEO) and diesel or gasoline. The following factors were studied three levels of mixing ratios between the (UEO) with each of diesel and gasoline [(Ratio of the diesel/ (UEO) (62%/ 38%, 66%/ 34% and 70%/ 30%) (Ratio of gasoline/ (UEO) (40%/ 60%, 45%/ 55% and 50%/ 50%)], three levels of filtering (without filter, one filter, and two filters) and three levels of feeding rate (2.0, 2.5 and 3.0 L/h). The best results of experiment were at mixing ratio of gasoline / (UEO) (50%/ 50%), filtration degree of two filters and feeding rate of 2.5 L/h.
