There are two main functions of the rear arch of the coal-fired steam boiler. The first function is to ignite, the second function is to keep warm and promote combustion. Furthermore, the length of the rear arch is decided by the types of coal. If the coal is flammable and volatile, the length of rear arch is shorter, otherwise, it is longer.
A steam boiler is defined as a vessel that captures and produces steam to either heat homes and businesses, or to provide energy for various industrial functions. The name “steam boiler” is typically used to refer to equipment that generates heat, but the term can technically be applied to any piece of equipment that utilizes steam for its
electric energy. The energy is transferred from the boiler to the turbine through high pressure steam that powers the turbine and generator. This separation of functions enables steam turbines to operate using a large variety of fuels, from clean natural gas to solid waste, including all types of coal, wood,

Today, most boilers use natural gas simply because it is clean and inexpensive. It has also become a preferred choice because it is a “Clean
A grade between bituminous coal and anthracite was once known as "steam coal" as it was widely used as a fuel for steam locomotives. In this specialized use, it is sometimes known as "sea coal" in the United States. Small "steam coal", also called dry small steam nuts (or DSSN), was used as a fuel for domestic water heating.
