Boiler-Tuning Basics, Part I. At that time the trend-tune program defaulted to a 2-minute window, and no one bothered to mention to me that the proper time span to tune drum level control to is 20 to 30 minutes. I also zoomed in on the drum level, which has a normal range of ±15 inches, though my trend range was ±3 inches.

Boiler: The mixture of pulverized coal and air (usually preheated air) is taken into boiler and then burnt in the combustion zone. On ignition of fuel a large fireball is formed at the center of the boiler and large amount of heat energy is radiated from it. The heat energy is utilized to convert the water into steam at high temperature and pressure.
ponents that distill from the boiler even in the absence of spray. There are three basic means for keeping these major problems under control. 1. External treatment: Treatment of water—makeup, condensate, or both, before it enters the boiler, to reduce or eliminate chemicals (such as hardness or silica), gases or solids. 2.

Nov 26, 2016 · Tray type Deaerator. Tray type deaerators contain perforated trays in the top of the Deaeration section. The bottom section acts as storage for boiler feed water. Feed water to deaerator enters into the perforated trays where the surface area and residence time is increased to contact with steam.
The boiler is not the heating system; it is only one of the parts in the global heating system. As shown in '''Figure 1''', a heating system consists of four main parts: Boiler/burner combination (the part producing the heat) Piping with pumps and valves (the part distributing the heat) Radiators and convectors (the part emitting the heat to the room)
Objective: To describe and explain the boilers’ functions and the two main types of boilers. What is a boiler? A water containing vessel in which water is heated under pressure Transfer heat from a fuel source (oil, gas, coal) into steam The steam or hot fluid circulates out of the boiler for use in various process or heating appliances.
A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat. Fluids are a subset of the phases of matter and include liquidsgasesplasmas andto some extentplastic solids.

The boiler in which the hot gases are inside the tubes and water surrounding the tubes is called fire tube boiler. e.g. : Lancashire boiler, Locomotive boiler. WATER TUBE BOILER The boiler in which the water is inside the tube and the hot gases surround them is called water tube boiler. e.g.:-Babcock and Wilcox BoilerO Externally fired and Internally fired tube Boilers.
There are two basic types of boilers: firetube and watertube. The fundamental difference between these boiler types is which side of the boiler tubes contain the combustion gases or the boiler water/steam. Firetube Boiler. In firetube boilers, the combustion gases pass inside boiler tubes, and heat is transferred to water between the tubes and the outer shell.
