When used in a central heating system, this is a self-contained appliance for heating air by transfer of heat of combustion through metal to the air.
Furnaces which recirculate the products of combustion and extract available heat to a point that causes condensation to occur. Some of this latent heat of vaporization is recovered as usable energy and results in higher operating efficiencies.
a combustion chamber; an enclosed structure in which fuel is burned to heat air or material
An enclosed heating device. Modernly, a box-shaped unit containing a burner, which is fed oil or gas through a pipe. The heat from the burning gas or oil is circulated, usually with the aid of a fan through ducts to areas to be heated.
A heating appliance that warms air around a heat exchanger. The air is conveyed by fan, into a central duct system to distribute warm air to all areas of the home or building.
An appliance used to heat air in a warm air heating system.
Equipment used to convert heating energy, such as fuel oil, gas, or electricity, to usable heat. It usually contains a heat exchanger, a blower, and the controls to operate the system.
an enclosed chamber in which heat is produced to heat buildings, destroy refuse, smelt or refine ores, etc.
a closed compartment that is used to warm up, to cook or to dry
a device for heating air and other materials
a device for heating air or any other fluid
a device for heating air or anyother fluid
a device found in the home used for heating
a device that heats air and usually blows the air through ductwork
a device that produces heat
a device used for heat ing
an enclosed space which provides for the combustion of fuel
an enclosure used for heating and can be found at the basement or at the attic
a place where combustion takes place
a steel or cast iron box connected to a series of duct work which runs through the house bringing hot air to grilles (registers)
a tank system in which fuel or electricity is used to warm air which is distributed through heating ducts throughout the space
a warm air central heating system that supplies heat to an air transfer
A tank fabricated for melting the glass batch.
The major component for heating a home. A device that facilitates the safe combustion of fuel to create heat, and the transfer of that heat to the living space.
a round brick structure in the blowing room built for the blowing of glass; in early times it was fueled by wood, later by coal, and now by gas.
An enclosure in which energy in a non thermal form is converted to heat, especially such an enclosure in which heat is generated by the combustion of a suitable fuel. An intensely hot place: the furnace of the sun; an attic room that is a furnace in the summer. A severe test or trial: endured the furnace of his friends' blame after the accident.
A heating system that uses the principle of thermal convection. When air is heated, it rises and as the air cools it settles. Ducts are installed to carry the hot air from the top of the furnace to the rooms. Other ducts, called cold air returns, return the cooler air back to the furnace.
An enclosed structure for the production and application of heat. In glassmaking, furnaces are used for melting the batch, maintaining pots of glass in a molten state, and reheating partly formed objects at the glory hole.
That part of the heating system in which the combustion of fossil fuel and transfer of heat occurs.
An enclosed chamber or container used to burn biomass in a controlled manner to produce heat for space or process heating.
The major component in heating a home. A device that facilitates the combustion of fuel and air to create heat.
An enclosed space of a boiler in which the fuel undergoes combustion.
melts the batch or cullet into glass, heated to around 2450°F.
a heating unit that heats air by transferring heat in a metal combustion chamber to the air and circulating it through the house in a network of ducts.
an enclosed fire used for heating something, such as water or metal
That part of an environmental system which converts gas, oil, electricity or other fuel into heat for distribution within a structure.
A heating unit that uses a forced air distribution system.
Common heating system in homes.
A type of space-heating equipment with an enclosed chamber where fuel is burned or electrical resistance is used to heat air directly without steam or hot water. The heated air is then distributed throughout a building, typically by air ducts.
A furnace is a structure with a chamber inside that can continuously heat raw materials to a very high temperature. It is used, for example, in metalworking.
An enclosed structure typically made of steel and fire brick that holds the hot glass in a ceramic vessel. 24 hours a day, seven days a week a one million BTU burner keeps the glass molten at a constant 2,150 degrees F. In this stage the glass is colorless and glows a bright white-orange. On the front of a furnace is a small, one foot square sliding door where a glass blower can access the molten glass using a blowpipe or punty.
A built up chamber in which fuel is burned to produce intense heat. Furnaces are used to heat plates, shapes, etc. to permit their being hammered or bent to a ship's form. A space or receptacle built in a boiler in which the combustion of fuel takes place.
An enclosed heating device powered by coal, oil, propane or natural gas.
an enclosed space for the burning of fuel. There are many kinds of furnaces, the type depending upon the fuel and the use to which the heat produced within it is put. Most familiar are the furnaces used in the heating of buildings. In the hot-air furnace, fuel is burned within an inner wall and air, led into a space between the inner and the outer wall, is heated and is led away to the various rooms of the building. Hot-water (hydronic) furnaces, by which water is heated to be led through pipes to radiators, and furnaces that turn water to steam for heating purposes are common.
A chamber, single or divided, constructed of stone, brick, or metal, in which materials are subjected to heat. Kinds of furnaces include: Air* Furnace; Blast* Furnace; Fusion* Furnace; Lamp* Furnace; Muffle* Furnace; Portable* Furnace; Reverberatory* Furnace; Sand* Furnace.
An enclosed space provided for the combustion of fuel.
A completely self-contained heating unit that is designed to supply heated air to spaces remote from or adjacent to the appliance location.
A unit which draws in cool air from an occupied space and passes the air through a heating chamber, combustion or electric, and then is returned to the occupied space; a heat system using air as the distribution fluid.
A combustion heating appliance in which heat is captured from the burning of a fuel for distribution, comprised mainly of a combustion chamber and heat exchanger.
1. A type of space heating system that heats air. The heated air is circulated throughout a home or building using air ducts and registers. 2. Equipment or enclosure used to convert energy in a fuel into heat for any purpose; a combustion chamber.
That part of a boiler or warm-air space-heating plant in which combustion takes place. (See Heating Equipment.)
