Internal layout of a three-pass fire-tube boiler. Package boilers are commonly called water or fire tube Boilers. Water tube boilers use convection heating, which draws the heat from the fire source, and passes against the generating tubes of the boiler, causing water inside those tubes to boil off into steam.
A sectional diagram of a typical steam boiler feed injector, simplified to show the major parts common to such injectors, showing typical proportions, and using colour and shading to hint at temperature, pressure, and velocity variations in the fluid flows. The SVG was hand coded using a text editor.
An exhaust stack takes the hot gases and transfers them away from the boiler. Boiler controls are there to make sure the hot water or steam is produced in a safe way. [5] In addition to these five key parts, a boiler also has a firebox, refractory, and return lines. A firebox contains the flame, created from the fuel and air.
Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the circulating water.
Boiler design is the process of designing boilers used for various purposes. The main function of a boiler is to heat water to generate steam. Steam produced in a boiler can be used for a variety of purposes including space heating, sterilisation, drying, humidification and power generation. The temperature or condition of steam required for ...
