subject: An industrial boiler installation [print this page] An industrial boiler installationAn industrial boiler installation
An industrial boiler installation, comprising an outer continuous shell within which is contained the water space of the boiler, a furnace and a plurality of smoke tubes for passage there through of the products of combustion of the furnace and the boiler having at least two fuel supply means, at least one of which extends through the shell and the water space, one of the fuel supply means supplying HCV fuel to the furnace and the other supplying LCV fuel to the furnace.
An Industrial autoclave installation comprising an outer continuous shell within which is contained the water space of the boiler, a furnace, and a plurality of smoke tubes for passage there through of the products of combustion of the furnace, and the boiler having at least two fuel supply means, at least one of which extends through the shell and the water space, one of the fuel supply means supplying HCV fuel to the furnace and the other supplying LCV fuel to the furnace, the boiler including primary fuel supply means operative normally to fire the boiler and an auxiliary fuel supply means operative to supply non-corrosive fuel to fire the Oil fired boiler and control means to render the primary fuel supply means inoperative and auxiliary fuel supply means operative prior to the boiler being placed in a "low load" condition, wherein the control means includes a pressure sensitive device operative to render the primary fuel supply means inoperative and the auxiliary fuel supply means operative when the pressure of steam produced by the boiler attains a first predetermined value, and operative to place the auxiliary fuel supply means in a "low load" condition when the pressure attains a second, higher predetermined value.
According to the present invention we provide an industrial boiler manufacturer comprising an outer continuous shell within which is contained the steam and/or water space of the boiler, a furnace grate and a plurality of smoke tubes for passage there through of the products of combustion of the furnace and the boiler having at least two fuel supply means, at least one of which extends through the shell and the steam and/or water space, one of the fuel supply means supplying HCV fuel to the furnace and the other supplying LCV fuel to the furnace.
