Questions for furnace? We have the answers!

1) How can we conduct a gas/energy consumption analysis and optimize the gas/energy usage for a muffle furnace?

To protect the muffle, a muffle furnace usually stays powered on at all times.

Gas consumption depends on the furnace sides, as well as the oxygen content requirement. When the furnace is not working with a load (during night shift, for example) the gas flow can usually be turned down to 30% - 40% of the working rate.

With an optimized structure and superior insulation design, our furnace is energy efficient. After reaching the required profile, the heating elements will work at about 50% or less of the maximum power output. This extends the lifespan of heating elements, and saves power. When the furnace is not working with a load, the insulation power of empty furnace is usually 20% - 35% of the max power output.

2) What are common spare parts that a customer should stock to guarantee uninterrupted operation of a belt furnace? How often are these parts replaced?

Typical spare parts include a belt, a brush, a Solid State Relay, a cooling fan, a thermal couple, heating elements, et cetera. Under normal working condition, our furnaces can run 3-4 years without needing any major parts replaced.

3) What does a customer need to do to prepare for a belt furnace installation?

The following elements must be ready before the belt furnace can be installed:

• - Power Supply
• - Gas Supply
• - Exhaust System
• - Water Cooling System

Our engineers will issue clear instructions on this preparation beforehand.

4) Is there a device that can be installed in a belt furnace to prevent parts from falling off of the belt?

Yes. A hearth plate with walls can be incorporated within the furnace. The belt would travel through the furnace on a metal hearth plate with side walls, which would prevent products from falling off the belt.

5) What types of control systems will work with the belt furnace’s operation system?

- Direct controllers on the furnace will offer basic control of parameters, such as zone temperature, belt speed, et cetera.

- A Windows-based industrial computer control system allows for easy profile setting, storage of multiple profiles, an straightforward working status monitor, and easy access to all operating data history.

- Beckhoff embedded control systems are suitable for customers that require a Beckhoff embedded control system.

6) What is the most common type of gas used to form a gas curtain in the furnace?

Nitrogen is most commonly used for a gas curtain. It is inert, safe, and effective in keeping air out of the furnace. Additionally, the cost is relatively low.

7) What is a FEC heater?

FEC stands for Fully Enclosed Coil, which means that the heating wires are embedded within the ceramic fiber boards. This design protects the heating wires, and also provides power distribution evenly in order to maintain the temperature uniformity.

8) What is a commonly used insulation material in a furnace?

Alumina silicate fiber is a high performance insulation material commonly used in our furnaces. It has small density, as well as good energy saving performance.

9) What are the requirements for a cooling water system?

Usually, the cooling water needs to meet requirements for pressure. Also, a proper corrosion inhibitor must be added.

Torrey Hills Tech will join Battery Show with its furnace systems for Li battery manufacturing

Taking place September 16-18 2014, in Novi, Detroit, Michigan, The Battery Show 2014 is the premier showcase of the latest advanced battery technology. 

Torrey Hills Technologies(http://www.beltfurnaces.com/index.html) will be introducing its belt furnace systems for battery manufacturing to all the exhibitors. Li ion battery manufacturing requires Ar/N2/H2 protective atmosphere at relatively high temperature.

Torrey Hills Tech HSA series furnaces are the best choice for Li ion battery manufacturing.

The HSA series furnace is an efficient furnace designed and used for heat treatment 

for processes such as LiFePO4. It features a low mass refractory heating chamber equipped 

with ceramic FEC (Fully Enclosed Coil) heating board. The HSA furnace has 6 independent 

zones able to reach 1150˚C, temperatures high enough to heat treat lithium iron phosphate. 

The temperature profiles are able to run at the desired heating rate to meet the required 

sintering temperatures under controlled atmosphere. Gas is independently controlled for the 

adjustment of air, nitrogen, hydrogen, and argon inflow. Temperature control zones allow the 

furnace to run at the proper heating rate to meet the needs for firing and curing. The 

conveyor system allows proper heating across the belt with little temperature variations. The 

furnace is monitored by type K thermocouples with each zone monitored by single loop PID 

temperature controllers. This enables precise and stable temperature control throughout the 

heating process to the cool down. 

The furnace is large enough to handle manufacturing processes for LiFePO4

applications. It has a 14” (35cm) belt width and a 130” (330cm) heated length. The conveyor 

system can run at speeds of 1-8 Inches/min. The HSA furnace is protected from 

overheating, over loading, and low gas pressures. It also comes equipped with anti shock 

protection on the doors during maintenance. Technical information and training will be given 

upon installation of the furnace to ensure proper practice for continued use. Emergency 

buttons and removable collection traps are also located on each end of the furnace. For the 

cleaning system, there is a rotating motor metal brush that cleans the belt so future products 

will not be contaminated.

Torrey Hills Technologies Hengli brand furnace win silver award!

(SAN DIEGO, CA, Aug. 5, 2014)   – Torrey Hills Technologies, LLC (THT) and Hengli Eletek, Co. Ltd  were jointly named as a Silver winner in Most Innovative Product of the Year in the Enterprise category of Best in Biz Awards 2014 International, for inventing a volatile organic compound (VOC) removal / thermal oxidizing system. Best in Biz Awards are the only independent business awards program judged by members of the press and industry analysts. Other winners of this prestigious award include Toshiba, Dell, BlackBerry, Epson, Lenovo, and more. For a full list of gold, silver and bronze winners in Best in Biz Awards 2014 International, visit: http://intl.bestinbizawards.com/intl-2014-winners.

 

Concerned about the negative impacts of modern manufacturing on environment, the Hengli/THT team designed a ground-breaking VOC removal system for their model AST belt furnace. Connected to the furnace exhaust, the VOC removal system eliminates VOC emissions before reaching outside air. Widely used in electronics manufacturing as solvents that are dried on a belt dryer and exhausted into the air, VOCs are one of the top causes for smog. The electronics manufacturing process contributes a significant portion of VOCs to air pollution, yet THT and Hengli are the first to achieve a green solution that allows VOCs to be oxidized into CO2 before being released into the ambient air.

“It was a pleasure to collaborate with Hengli on this important solution," said Ken Kuang, President and CEO of THT. “We are honored to be named as Silver winner for the 2014 Best in Biz Awards, and we are confident about the positive impact of this technology on environment.”

Torrey Hills Technologies, LLC ( http://www.torreyhillstech.com , http://www.beltfurnaces.com ) is a leader in developing and delivering quality yet affordable equipment and supplies for multiple industries.

Ultrasonic Belt Cleaner/Cleaning for Belt Furnaces - A Presentation

An ultrasonic belt cleaner utilizes ultrasound technology with transducers, which are positioned in the cleaning tank. These transducers emit sound waves in a purifying solvent, which thoroughly scours the belt on conveyor belt furnaces. Compared to metal brush cleaning, this method cleans the belt faster, with more precision and consistency. For more information, please visit www.beltfurnaces.com.
