In a steam-boiler the burning fuel is enclosed either by fire-brick or a "water-jacket," forming part of the boiler.
Fixed: a barrel-casing, which is also a water-jacket, and breech-casing.
He pulled the Maxim's block and threw it away; shot the water-jacket full of holes.
A double cylinder formed a water-jacket, connected with a water and steam chamber above, and a water-chamber below.
In the second place, the size of the cylinders and the consequently large extent of water-jacket surface, complicated the problem.
The loss of heat through the water-jacket is thus less in the case of a high-compression than in that of a low-compression motor.
It is operated by the gases of the explosion, has a water-jacket that allows 3000 rounds to be fired without refilling.
It does not heat fast, so has no need of a water-jacket, any surplus heat being removed by a system of radiation.
To the right is the fire-box, surrounded on all sides by a water-jacket in direct communication with the barrel of the boiler.
They are all water-cooled, having a water-jacket of (p. 050) sheet metal entirely surrounding the barrel.
