Desarrollo de un prototipo recuperador de calor residual de lecho empacado de caliza y coque.

In this paper a prototype waste heat boiler packed bed of limestone and coke, which simulates the capture of flue gases from the chimney of a vertical furnace for calcination of limestone and lime gain was designed. The use of these gases is intended to preheat a new limestone and coke material. These gases are usually driven environment with temperatures above 545 ° C. The recovery consists of two stainless steel tubes, one fixed and one mobile, the mobile is the recovery tube as such, the fixed tube serves to support the recovery (mobile tube) having an inner diameter of 0.096 m and a height of 0.25 m, the gas used is air represented by the fan RPM. The packed bed is limestone and coke in sizes of 1 and 1.5 cm, the temperature is the variable of interest was recorded using 4 thermocouples located at 4 different heights inside the boiler (1, 7, 13 and 19 cm) Data were entered into arrays in Excel 2010 Advanced Function of multiple linear regression. Excel identified two equations predicting the behavior of the temperature of the limestone and coke. It was found that the heat recovery is 43% limestone and coke is 53% in a time of one hour.
