MODEL BOILERS The furnace is lined with a strip of stout sheet iron, 7 inches wide and 19-1/4 inches long, bent round the barrel, which it overlaps for an inch and a half. Several screws hold lining and barrel together. To promote efficiency, the furnace and boiler is jacketed with asbestos --or fire-clay round the furnace -- secured by a thin outer cover.

This is common in the lower furnace of recovery boilers. For units firing coal, boilers having maladjusted burners or utilizing staged firing (with overfire air ports) can be more susceptible to larger localized regions possessing a reducing atmosphere, resulting in increased corrosion rates. Components typically affected: Waterwall tubes.

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled …
