KEY COMPONENTS OF BOILERS | Boilers Guide

Historically, economizers have only been used in large-scale power plants. However, the demand for more efficient boilers within industry and marine means that economizers are now far more commonplace. An economizer is a heat exchanger that is placed in the exhaust from a boiler or in the exhaust funnel of the main engine of a ship.

Marine Boiler Constructions. A Scotch marine steam boiler consists of a steam drum and one to four fire-tubes in which furnaces heats the steam-boiler. A water-tube Marine

High Pressure Low Emission Scotch Marine Boiler | 4

Scotch Marine Boiler with capacities From 30 to 1,500 BHP 1,004 to 50,213 MBTU/HR. 15 PSI Steam 30 PSI Water (60 PSI Water Optional) PACKAGED SCOTCH MARINE HIGH PRESSURE BOILERS Three and four pass dry back boilers have tube sheets with large temperature variations and this results in premature tube failure and cracks in the tube sheets.

James G. Speight, in Reaction Mechanisms in Environmental Engineering, 2018. 5.2.3 Boiler Slag. Boiler slag is a byproduct produced from a wet-bottom boiler, which is a special type of boiler designed to keep bottom ash in a molten state before it is removed. These types of boilers (slag-tap and cyclone boilers) are much more compact than pulverized coal boilers used by most large utility
