Inspection -- The objections given above in the consideration of the inability to properly clean fire-tube boilers hold as well for the inspection of such boilers.

Steam, Its Generation and Use

The limitations in the draft area of fire-tube boilers as affecting economy have been pointed out.

Table 2 shows the difference in floor space occupied by fire-tube boilers and Babcock &

Steam, Its Generation and Use

The fire-tube boiler will be so completely demolished that the question of repairs will be shifted from the boiler to the surrounding property, the damage to which will usually exceed many times the cost of a boiler of a type which would have eliminated the possibility of a disastrous explosion.

Steam, Its Generation and Use

In vertical fire-tube boilers using a water leg construction, a deposit of mud in such legs is an active agent in causing corrosion and the difficulty of removing such deposit through handholes is well known.

Steam, Its Generation and Use

_ -- Having filled the boiler with water to the usual height, that is to say, about four inches over the crown of the fire-tube, I throw in several shovelfuls of coal or coke towards the bridge, left and right, keeping the centre clear; then I place the firewood in the centre, throw some coals on it, light up, and shut the door.

The Stoker's Catechism W. J. Connor

The concave bridge was built close up to the bottom of the fire-tube, and resembled a small archway, and extended down to within nine inches of the bottom or shell of the fireplace; the convex bridge was built on the bottom of the shell and reached to within nine inches of the fire-tube.

The Stoker's Catechism W. J. Connor

_ -- The bridge should be about nine inches from the crown of the fire-tube, if it were eight the draught would be curtailed, if it were ten the draught under the bars would be diminished, through much air passing over the bridge instead of under the firebars.

The Stoker's Catechism W. J. Connor

_ -- How high should the top of the bridge be from the crown of the boiler or from the fire-tube?

The Stoker's Catechism W. J. Connor

Water-tube boilers in general are from the nature of their design more readily accessible for cleaning than are fire-tube boilers.
