Brickwork

brickwork, brick masonry

Brickwork 

a system of barriers in a boiler unit that separates the firebox and gas flues from the environment. Brickwork is used in boilers that do not have all-welded, gas-tight shields. The purpose of boiler brickwork is to impart the proper direction to the flow of flue gases in the boiler unit, to reduce the heat losses to the surroundings, and to prevent suction of outside air into the gas flues in case of a rarefaction in them or leakage of the flue gases into the boiler room if the pressure in the gas flues exceeds atmospheric pressure. The outside temperature of boiler brickwork should not exceed 55°C for an air temperature of 25°C. Boiler brickwork is made of fireclay bricks, refractory concrete, or some other refractory material.

The houses in many parts fell outwards; thus forming in the middle of the streets little hillocks of brickwork and rubbish.
I advanced over the grass, and observed here and there, where the ground rose a little, some moldering fragments of brickwork.
Only, since our last journey thither, the walls had taken a grayer tint, and the brickwork assumed a more harmonious copper tone; the trees had grown, and many that then only stretched their slender branches along the tops of the hedges, now bushy, strong, and luxuriant, cast around, beneath boughs swollen with sap, great shadows of blossoms of fruit for the benefit of the traveler.
