Her boilers and highpressure engines had been brought all the way from Cincinnati and could produce 39.72 horsepower.

By the 1890, boilers were producing 160 psi, and the triple expansion horizontals became standard.

The boilers produced steam at a pressure of 235 psi (16 atmospheres).

The boiler produces both heat and electricity.

Most boilers produce steam to be used at saturation temperature; that is, saturated steam.

But a boiler does not produce energy, even in the sense that Booker appears to mean.

The smoke that these boilers produce is as bad as it looks and smells.

These new boilers produce less steam than the original ones.

At the plant here, a boiler produces high-pressure steam that drives a 55-megawatt generator.

The four other, smaller oil-fired boilers at the plant produce only steam.
