Energy efficient and clean provision of steam in conjunction with high levels of operational safety and system reliability are essential requirements for production facilities and industrial plants. In order to design boiler house concepts appropriate for the task in hand, individual requirements must first be established so that
Heating Surface. • Surface area available for heat transfer is very important in boiler design. • Most larger firetube boiler manufacturers build boilers at 5 sq ft of heating area/BHP. • Firebox Boilers are built at 4-5 sq ft/BHP. • Vertical Firetube Boilers can be as low as 3 sq ft/BHP

Abstract. Introducing modern boiler concepts in the design of thermal power stations is nowadays becoming mandatory, not only from an economic point of view of new investments, but also as a significant and pro-active step towards the reduction of greenhouse gases & dust emissions by the enhancement of efficiency.
considering the numerous problems connected with their con- struction, it might be possible to place before this Congress both a concise and yet a fairly exhaustive summary of the present process of manufacture. That these few remarks cannot claim to be more than a very brief outline will, it is hoped, soon be apparent; but

BOILER CONSTRUCTION. · JT would appear that riveted construction for boilers began in the early nineteenth century, and, according to early works on the subject, wrought-iron riveted boilers constructed from plates only 3 ft. by 1 ft. were in use at that time, working at pressures up to qo lb.fsq. in. A present-day tendency is
Water does not boil from the surface, but bubbles of steam form throughout the mass and rise to the surface. This action is very violent in steam-boilers, and bubbles of steam rise so rapidly as often to carry considerable water in mechanical suspension into the steam. This action is called "priming," and it occurs most fre-.
