Boiler backpass

WebConsumers wanted the boilers to be as small as possible to minimise the amount of floor space needed by the boiler house, and hence increase the space available for other purposes. Boilers with smaller dimensions (for the same steam output) tend to be lower in capital cost. Table 3.2.4 demonstrates this, and other factors.
