Abstract
Disclosed herein is a compact (e.g., one-piece) refractory cast iron combustion chamber mold for a circulating fluidized bed boiler for the combustion and/or gasification of biomass, waste, lignite and mixtures thereof, and a method of obtaining a combustion chamber with this mold.
Claims10
A single-piece refractory cast combustion chamber mold for circulating fluidized bed boilers that provides the combustion and/or gasification of biomass, waste, lignite, and/or mixtures thereof, comprising:
- at least one inner mold in one-piece, for forming inner walls of the combustion chamber,
- at least one outer mold in one-piece, for forming outer walls of the combustion chamber by wrapping around the at least one inner mold,
- anchoring metals that are placed between the at least one inner mold and the at least one outer mold such that concrete is held when the concrete is poured to obtain a combustion chamber between the at least one inner mold and the at least one outer mold,
- a thermal insulation layer placed on the outer facing surfaces of the anchoring metals to isolate heat,
- at least one fitting which enables the at least one inner mold and the at least one outer mold to be connected to each other at a predetermined distance from each other and, when removed, enables the at least one inner mold and the at least one outer mold to be separated from each other to obtain the combustion chamber, and
- a refractory layer that is poured and oven-dried between the thermal insulation layer and the at least one inner mold to make the combustion chamber resistant to temperature.
A method of obtaining a one-piece refractory cast iron combustion chamber for circulating fluidized bed boilers, enabling the combustion and/or gasification of biomass, waste, lignite, and/or mixtures thereof, the method comprising:
- disassembling a one-piece inner mold for forming inner walls of a combustion chamber, and a fitting for connecting a one-piece outer mold for forming outer walls of the combustion chamber by wrapping around the one-piece inner mold, with a predetermined distance in-between,
- placing anchoring metals between the disassembled one-piece inner mold and one-piece outer mold,
- placing a thermal insulation layer on outer facing surfaces of the anchoring metals,
- connecting the one-piece inner mold and the one-piece outer mold are connected with the fitting,
- closing all spaces of the one-piece inner mold and the one-piece outer mold that open to the outside,
- pouring a refractory layer between the thermal insulation layer and the one-piece inner mold,
- pouring concrete between the one-piece inner mold and the one-piece outer mold,
- holding and drying the concrete, and
- oven drying and holding the mold to remove moisture.
