To quickly assess the difficulty of the text, read a short excerpt:
It thus becomes necessary as a next step to ascertain this last quantity, and therefore to ascertain the height of chimney. This is, in the case of con- siderable power, as here, to be determined by the principles de- tailed in §§ 157 and 158. A height of 125 feet may be taken as the result of this investigation. A well-designed chimney of this altitude should permit the combustion of 15 pounds per square foot (7.5 kgs. per sq. m.) of grate with a mar- gin of at least one third for contingencie...s. On this basis, the 36o THE STEAM-BOILER. area of grate must be 82 square feet {t& sq. m.) and the area of heating surface 2460 square feet (228 sq. m. nearly). This is to be distributed among two or more boilers ; since, although a thousand horse-power, even, may be, and sometimes is, ob- tained from a single boiler, it is usually found inexpedient to concentrate power to such an extent. A boiler of 5 feet (1,5 m.) diameter and 2\ or 3 diameters long has become a very common and very satisfactory size.
