30TPD End Fired Furnace Natural Gas Flint Container Glass
1. Brief Description
An End-Fired Furnace (is also called as End-Port Furnace or
Horseshoe-Fired Furnace) is an industrial thermal processing unit
where combustion burners are positioned at one or both ends of
the furnace chamber. The hot gas flow from combustion moves along
the furnace direction, transferring heat through a glass melting
furnace designed with longitudinally arranged combustion ports and
a U-shaped flame path.
The end fired furnace has a small flame coverage area, the flame
reversing brings periodic temperature fluctuation and hot spot
movement.
In addition, the number of port limits the furnace width and
furnace scale. End fired furnace is suitable for making all kinds
of hollow products (bottles, jars, vessels, chemical instruments,
bubble shells, glass tubes, etc.), pressing products and glass
balls without special requirement on the quality of glass.
Its typical melting capacity is 30 – 500 t/d, in some cases up to
700 t/d can be achieved. Limitations in furnace size result from
flame length and crown span width, especially of the burner ports.
JEFFER Engineering has designed and supplied the end-fired furnaces
for the customers in China and aboard.
2. Furnace structure
Melting section
It is the part that melts the batch material and cleans and
homogenizes the glass liquid. The upper space in the melting part
is called the flame space, and the lower part is the melting tank.
The flame exits the burner through ports where preheated air is
added to increase flame efficiency.
Dog house
The ingredients enter the furnace through the kennel, and the heat
is transferred through the flame space into the glass liquid.
Air, gas access
After the heated air and gas exit the regenerator, they flow
through this channel into the pre-chamber for mixing. This is also
the channel through which the flue gas flows from the flame space
into the regenerator.
pre-chamber
After the air and gas flow out of the channel, under the action of
the vortex motion of the air flow and the diffusion and collision
of molecules, the air and gas will mix before flowing into the
furnace.
3. Furnace melting technology system
Furnace melting technology includes temperature, pressure,
bubbling, glass level, fuel, reversing system, etc. The temperature
refers to the temperature of the furnace, not the temperature of
the entire furnace. The temperature profile is from the melting
tank through the length of the furnace.
The furnace pressure is the static pressure of the gas system,
which is determined by the pressure distribution curve. The
stability of the shape and position of the bubbles is an important
indicator to measure the melting performance, which will also
affect the production capacity of the furnace and the quality of
the molten glass.
