Furnace Combustion w/ Control Components |
|
| We most commonly install Eclipse Thermjet
burners on furnaces. The Thermjet is an industrial burner
ideally suited for glass melting furnaces for a number
of reasons. Most importantly Thermjets provide a wide
turndown ratio of 50:1. This means the gas/air ratio can
be adjusted to stay in proper proportion from minimum
to maximum output over a broad range. Proper air/gas
mixture ratios are important to fuel efficiency. |
|
| These burners are also designed to promote
good circulation inside the furnace. They are designed
to accommodate National Fire Protection Agency approved flame safety systems and
are delivered with a spark plug and port for a U.V. sensor.
The burner we recommend also has stainless steel internals
and can be operated with preheated air. |
|
| These burners require forced air provided
by a combustion air blower. The industry standard for
many years has been to use a fixed speed blower and control
the air volume with a mechanical butterfly valve via
the temperature control. In many cases this is the best
option; however, for the past 20 years we have been
using variable speed blowers. With a variable speed blower,
the speed of the blower is controlled by the temperature
control. This results in a considerable savings in electric
consumption. |
|
| We also recommend utilizing one blower
for furnaces and a separate blower for glory holes and
other gas/air fired equipment. This results in further
cost savings as the blower for the glory holes can be
shut down during times the glory holes are not in operation. |
|
|
| There are usually two systems that support
a burner. The first is the control system. The control
system can be manual but most commonly utilizes a programmable
temperature control. The second system is the flame safety system that monitors
the burner flame. |
|
|
| Our most common systems are listed below. Please call for specific applications.
We will be happy to work with you and design a system
to meet your needs. |
|
|
| All systems provided by HUB are delivered
with installation and operation instructions. We also
provide training in the operation of new equipment, ongoing
assistance and technical support. |
|
| We carry far more
parts than are listed. Please call us if you
don’t see what you’re
looking for. |

| Eclipse Burners |
|
The Eclipse ThermJet burner uses staged
air & gas mixing to provide a wide turndown range—50:1, the lowest emissions in the industry, and the
highest operating velocity available. Listed are burners
with stainless steel internals for 300–799° F preheated combustion air. |

Electric Furnace
Heating Packages |
|
| To better meet our customers’ needs, we have decided to add electric packages as an option for furnace heating. The furnace is our same tried and true free standing crucible design with moly disilicide elements instead of a burner. |
|
| We have selected Duralite as a vendor for these packages. Duralite has been providing electric heating systems since 1946 and has experience in the glass melting field. They offer options that are very safe and extremely reliable. We welcome your inquiries about our electric furnaces, and we would be happy to answer any questions and provide you with a quote. |

|
| No furnace system should be operated without proper training and safety precautions. We are committed to safety. Our transformer system provides galvanic isolation—there is no direct connection between the power line and the heating element. The result is a system that has no significant voltage difference versus ground. This means that you cannot be shocked. |

| Recuperators |
|
| Recuperators use exhaust gas to preheat
combustion air. They are a great solution to deal with rising
energy costs and increased concern over reducing waste. |
|
We have been using a simple design since 1986, and customers who have switched from a brick flue to
a recuperator claim a 30% energy savings. This is a true exhaust
gas recuperator that preheats combustion air with exhaust gas
only after it has left the furnace interior.
|
|
The design is very simple. There
are no small passages to keep clean and very little combustion
air pressure drop. It actually stays cleaner than a brick
flue thus reducing maintenance. |
|
| We highly recommend recuperators
on new furnaces and will be happy to help retrofit one to an
existing application. In many parts of the country, energy
companies will offer incentives for upgrades that reduce consumption. |

| Recupar—$ 1,760.00 |
