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.
Superheated steam is steam at a temperature higher than the saturation temperature corresponding to pressure. For example, a boiler may operate at 415 psig (pounds per square inch gauge). The corresponding saturation temperature for this pressure is 483°F, and this will be the temperature of the water in the boiler and the steam in the drum.
Sep 15, 2017 · Boilers are typically installed on a slab or small pedestal at each support beam. This does not allow for access below the boiler. When tubes leak within the boiler, the steam will blow either into the gas stream or onto adjacent tubes. When a boiler is shut down, these leaks can pool on the floor.
KEY COMPONENTS OF BOILERS. Hydronic systems can heat via hot water or steam, depending on the type of boiler used. The boiler is the part of the system that heats the water to be distributed. The key elements of a boiler include the burner, combustion chamber, heat exchanger, exhaust stack, and controls.
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. Today, larger firetube boilers are over 1,500 boiler horsepower (about 50,000 pounds per hour.
