Firebox—the area of a boiler where the burners are located and where radiant heat transfer occurs, p. 296. Fire tube boiler—a device that passes hot combustion gases through the tubes to heat water on the shell side, p. 298. Igniter—a device (similar to a spark plug) that automatically ignites the flammable
Boilers are also sometimes described by their key components, such as heat exchanger materials or tube design. Two primary types of boilers include Fire- tube and Water- tube boilers. In a Fire-tube boiler, hot gases of combustion flow through a series of tubes surrounded by water.

The construction and maintenance routine of a typical fire tube boiler happens to be very simple. Fire tube boilers usually consist of a single furnace tube and a burner. Hence, the control systems meant for heating purpose inside these boilers is kept very simple.
Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate, but they are limited generally to capacities of 25 tons/hr and pressures of 17.5 kg/cm 2. Figure 2.2 Fire Tube Boiler
Fire Tube Boilers. In firetube boilers, the combustion gases pass inside boiler tubes, and heat is transferred to water on the shell side. Scotch marine boilers are the most common type of industrial firetube boiler. The Scotch marine boiler is an industry workhorse due to low initial cost, and advantages in efficiency and durability.
As a guideline, competitive fire tube boilers for steam speeds up to 12,000 kg / hour with pressures up to 18 kg / cm2. Fire tube boilers can use fuel oil, gas or solid fuel in their operations. Working: The ignition process occurs in the pipe, then the heat generated is delivered directly into the boiler containing water.
Whatever the type of fuel being fired, all high pressure boilers are bound to have a tube failure during the course of their working life. Did you know that a single tube failure in a 500 MW boiler requiring four days of repair work can result in a loss of more than $1,000,000 apart from the generation loss?
The coiled tube boiler is a type of Water Tube Boiler in which a cylindrical furnace envelope is formed by multistart, helically-coiled tubes in which water is boiled. Firing is by oil or gas and the burner is provided usually in the base, although sometimes in the roof of the furnace.

process. The primary measurements required under the Boiler Area Source Rule are flue gas oxygen content and flue gas carbon monoxide content at the high-fire or typical operation load. a) Examine the combustion control components (i.e., the system controlling the air-to-fuel ratio) and ensure it is functioning properly.
The horizontal fire-tube boiler is also typical of marine applications, using the Scotch boiler; thus, these boilers are commonly referred to as "scotch-marine" or "marine" type boilers. Vertical boilers have also been built of the multiple fire-tube type, although these are comparatively rare; most vertical boilers were either flued, or with cross water-tubes.

KEY COMPONENTS OF BOILERS. Hydronic systems can heat via hot water or steam, depending on the type of boiler used. The boiler is the part of the system that heats the water to be distributed. The key elements of a boiler include the burner, combustion chamber, heat exchanger, exhaust stack, and controls.
Where as in fire tube boilers hot gases from combustion travels through the tubes. flue gases produced from furnace where fuel is burnt. Water tube boiler design and working. In a typical Water tube boiler design as shown in the figure, it consists of two drums the steam drum and the water or mud drum.
Major Components of Boilers. The ashes fall through the fire grate into a (often) removable box. Grate: Grate is a series of bars or narrow plates in the bottom of the fire box. The ashes fall through the grate into the ash pit. Pressure Gauge: Indicates the pressure of the steam in the boiler.

This 3D model shows all major components associated with a typical three pass fire tube boiler, these include: Shell – fired pressure vessel. Burner – used for combustion. Corrugated furnace – where combustion occurs. Tubes – used to direct exhaust gasses through the shell. Tube sheets – used to hold the tubes in position.
Tube failures are classified as in-service failures in boilers. These failures can be grouped under six major causes: Stress rupture; Fatigue; Water side corrosion; Erosion; Fire side corrosion (Called also as High temperature Corrosion) Lack of quality control. These lead to twenty-two primary causes that can cause a tube failure in a high pressure boiler:
