Scotch marine boiler - Wikiped

A "Scotch" marine boiler is a design of steam boiler best known for its use on ships. Sectional diagram of a "wet back" boiler The general layout is that of a squat horizontal cylinder. One or more large cylindrical furnaces are in the lower part of the boiler shell. Above this are many small-diameter fire-tubes. Gases and smoke from the furnace pass to the back of the boiler, then return through the …

Understanding Steam & Boiler Heating Systems | HomeAdvis

Boiler Systems Operation In steam heating systems, a boiler furnace heats water by means of a gas or oil-fired burner and turns it into steam. The steam travels through pipes to radiators or convectors, which give off heat and warm the room. As the steam cools, it condenses back into water, and returns to the boiler to be heated again.

Boiler (power generation) - Wikiped

A boiler incorporates a firebox or furnace in order to burn the fuel and generate heat. The generated heat is transferred to water to make steam, the process of boiling. This produces saturated steam at a rate which can vary according to the pressure above the boiling water. The higher the furnace temperature, the faster the steam production.

Most of the manufacturers have not improved their design at all!!! One of the largest obstacles to an efficient design (70% or higher efficiency is possible) is the amount of money needed to develop the design and the cost of producing such a furnace. Most consumers can not justify 8 or 10 thousand dollars for a furnace.
