Difference Between a Heater, Furnace, and Boiler In the middle of this frigid winter, you may wonder what device is causing your living room to maintain that comfortable 72 degree temperature. Most homes are equipped with a central heating system, though the parts that make up that heating system can be a bit confusing.
Water Tube Boilers - In contrast to fire tube boilers; a water tube boiler uses the water rather than the heat which is contained inside of a system of interconnected tubes. The heat moves around the tubes, thereby heating the water within the tubes and gradually transforming it into steam.
What makes Econoburn's thermal technology so special is the proprietary closed-loop design featuring its unique gasification process. By forcing a downward flow of gas into a second combustion chamber, these boilers produce cleaner, and more cost-effective, thermal heat, which yields far more energy per pound of wood that's burned.

Fire-tube boiler: Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point.
boilers and pipes to a common discharge must be secured. The blow-off valves on the operating boiler shall not be opened until the blow-off valves on the unit being removed from service are closed and locked. All lockout/tagout procedures should be in place. Water-tube Boilers: If compatible with cleaning, boilers should be cooled to room
Boiler Tubes are metal tubes located inside of boilers that heat water in order to produce steam. There are two major types of tube boilers: water-tube boilers and fire-tube boilers. In water-tube boilers, water circulates inside the tubes and is heated externally by hot gases generated by the furnace.
