This paper shows how Cuban bagasse boiler practice began simultaneously with the design of the spreader-stoker boilers RETO and the retrofitting of the horse-shoe furnace German boilers into the RETAL ones. Now the main trend is the retrofitting of the boilers RETO for suspension burning using two systems: the vertical swirl or tangenital fired furnace; and the horizontal swirl furnace. In this paper the main technical characteristics and parameters are presented, as well as the results of the tests with different boilers. Data about temperature gas concentration profiles are different furnaces are also included. The conclusion is that the horizontal swirl furnace is actually the most promising technical solution for the suspension burning of a coarse and polidispersed bagasse like the Cuban one. The generalization of the bagasse suspension burning in horizontal swirl furnace boilers by retrofitting of the existing ones is a present task for the Cuban sugar industry, as well as the design of new high steam parameter boilers using this combustion system.
