The popularity of the "Boiler Operators Handbook" has prompted the issue of this revised and completely updated edition, which examines the change of emphasis from coal-fired to oil- and gas-fired boilers. The new "Boiler Operators Handbook" will help the operator carry out his important work with skill and efficiency. The good management of a boiler plant should ensure the production of good quality steam in a safe and fuel-efficient manner to minimise air pollution. All these issues are emphasized throughout the new edition. The NIFES consulting group has been responsible for the training of boiler operators since 1954, and this high level of experience is combined with the very latest technological advances to make this new edition essential reading for the boiler operator.

The popularity of the Boiler Operators Han ook has prompted the issue of a revised edition. Other than a relatively small number of developments, essen tially associated with solid fuel firing methods using the fluidised bed technique, no radical changes have occurred since the first edition of the Handbook was issued in 1969. In revising a work of this kind there is a great temptation to omit practices that are now less common in the UK. In view of the enormous pressure on Global energy resources, however, the chapters dealing in methods of hand-firing have been retained in the hope that they may be of value to those in the less developed nations where energy problems are infinitely greater than ours. High combustion intensity boilers, commonly known as Package Boilers, of the Shell Construction design, have now much greater steam output than their predecessors and the need for high levels of maintenance and operating skills remain as essential as when this group of boilers first appeared on the market. Also the standard of water treatment required is probably higher than the Operator has been accustomed to. The Health and Safety at Work Act re-emphasised the continued need for adherence to the principles that ensure a pressure vessel be maintained in a safe condition at all times. Accordingly the revised edition of the Boiler Operators Handbook has en larged its sections on Safety and the Clean Air Act."
