Abstract
A device, which conveys and handles material from a combustion boiler, includes at least one conveyor belt and a housing surrounding the conveyor belt. The conveyor belt includes at least one horizontal collection area and a handling area. The housing includes at least one outlet for the material. Furthermore, the handling area has a first length of at least 10 m and an inclination of at least 38°. Some arrangements relate to a corresponding combustion plant and to a method for handling hot ash.
Claims15
A device for conveying and treating material from a combustion boiler, having at least one conveyor belt and a housing surrounding the conveyor belt, wherein the conveyor belt has at least one horizontal collecting region and a treatment region, and the housing has at least one outlet for the material, and furthermore the treatment region has a first length of at least 10 m and a slope of at least 38°.
A plant comprising at least one combustion boiler, having at least one bottom opening for delivering material, and at least one device for conveying and treating material from a combustion boiler, each device having at least one conveyor belt and a housing surrounding the conveyor belt, wherein the conveyor belt has at least one horizontal collecting region and a treatment region, and the housing has at least one outlet for the material, and furthermore the treatment region has a first length of at least 10 m and a slope of at least 38°, and wherein the collecting region is arranged below the at least one bottom opening, and at least one silo for the material is provided below the outlet.
A method for conveying and treating hot ash of a combustion boiler, comprising at least the following steps:
- a) delivery of the hot ash from a combustion boiler onto a horizontal collecting region of a conveyor belt arranged in a housing, such that the ash is transported with varying dwell time in the collecting region,
- b) rearranging the hot ash, such that at least some of the ash is held back with a shorter dwell time in the collecting region,
- c) transporting the ash in an inclined treatment region having a first length of at least 10 m and having a slope of at least 38°, an opposed air flow for cooling the ash being generated, and
- d) discharging the ash from the housing.
