Embodiment Construction

[0029] The systems described herein can be better understood from the following detailed description of the accompanying drawings.

[0030] figure 1 A schematic diagram of the combustion zone 1 of a conventional roller hearth kiln is shown, with conventional burners 2 located in the kiln side walls.

[0031] Existing tunnel kilns have burners 2 which are divided into firing groups. A typical tunnel kiln may have from 3 to 40 firing groups. Each module of the kiln is about 2-3 m long and the separation gap between burners on the same side of the kiln is 0.75-1.5 m. The burners on the opposite side are random and not aligned.

[0032] In a preferred mode of the invention, the combustion zone comprises a plurality of burners divided into groups, each burner comprising control means such as solenoid valves, wherein the groups of burners are arranged in a side-rotating arrangement and according to the current Time intervals are activated independently and alternately on loop co...

Abstract

The present invention relates to a combustion system for the production of linings, comprising a roller furnace having walls with insulations, and being divided into different regions with different temperatures, the burning zone (3) of the system further comprising a plurality of burners (2, 4), in which the burners (2, 4) are located in the ceiling and / or in the floor and / or in the sides of the furnace and preferably burn in the direction contrary to the direction of advance of the load, horizontally.

Description

technical field [0001] The present invention relates to an improved combustion system in burners for industrial kilns, more particularly roller kilns for the manufacture of ceramics (floor and wall tiles). Background technique [0002] Roller kilns are well known in the art and have been used for decades for firing wall and floor tiles, among other things. [0003] The operation of such kilns is basically as follows: ceramic products, bricks, etc., hereinafter called "burden", enter the kiln in their "raw" form and move towards the opposite side, and come out in a "fired" form. However, for each product to be fired there is a different ideal internal temperature profile for each part of the kiln in order to give the material the desired structural properties. For example, the temperature of an earthenware vessel is about 1000°C. The temperature of the sanitary ware is about 1200°C. Other temperature ranges can also be found, such as 1450°C for hard ceramics, 1600°C for hi...
