Types of Boilers

Information on boilers specializes a wide class of water and hot water making units known as ICI central heating boilers. Because of variations in their features and quality, ICI central heating boilers are classified in three ways.

Boilers are basically subdivided into water tube or fire tube models. These designations indicate the way the water and flue gases are designed to pass through it.
Boilers are sometimes categorized by their warm resources. For example, central heating boilers are often known as oil-fired, gas-fired, coal-fired, or strong fuel-fired central heating boilers.

Coal-fired central heating boilers can be further divided based on the equipment used to fire the furnace. The three major types of boilers in coal-fired furnace subclasses are,

  • Pulverized-coal (PC) shot,
  • Stoker-fired, and
  • Fluidized-bed burning (FBC) central heating boilers.

Boilers are also recognized by their strategy of production. Built central heating boilers are assembled in a manufacturer, attached on a skid, and carried to the website as one package ready for wiring to auxiliary pipes. Shop-assembled central heating boilers are built up from a number of personal pieces or sub-assemblies. After these parts are arranged, connected, and examined, the complete model is delivered to the site in one piece. Field-erected central heating boilers are too large to carry as a complete setup. They are constructed at the construction site from a sequence of personal elements. Sometimes these elements require special carry and raising factors because of their size.

In the burning step, two fundamental processes must occur to achieve this purpose. First, the petrol must be supplied together with sufficient fresh air to allow continual burning. The warmed flue gas created by the burning process must then move the thermal power to a substance such as water or water. Various elements within the furnace are required to promote efficient burning and warm move. Their design will depend on factors such as the form of fuel and the strategy chosen to move warm power. The ICI central heating boilers are created in a variety of sizes to get rid of fossil petrol, oil, natural gas, biomass, and RDFs as well as other energy resources and petrol blends. Most ICI central heating types of boilers are categorized as either water tube or fire tube central heating boilers, but other styles such as certain, coil-type, and tubeless (steel shell) central heating boilers are also manufactured.


The basic purpose of any ICI furnace is to turn the chemical power in petrol into warm energy that can be used to generate water or hot water.
