Two standard variations of ceramic insulation for box furnaces are rigid ceramic fiber boards and flexible blankets. They are manufactured using strands of refractory silicate compressed or woven into a lightweight textile, with excellent inherent strength and low thermal conductivity.
A comprehensive solution for industrial combustion safety helps plant owners and operators improve safety and reliability while reducing risk and optimizing the efficiency of fuel-fired equipment used in process heating operations.
The importance of safety in industrial ovens, furnaces and other combustion systems cannot be overstated. Hundreds of combustion-related incidents and near misses occur every year, resulting in millions of dollars in business interruption, facility damage, lawsuits, fines, litigation and lost marketshare.
A reheating pusher furnace, with an initial production capacity of 90 tons/hour, is integrated into a rolling mill producing merchant bars and rebars at Polish steelmaker Cognor’s plant in Krakow. The company contracted Fives to improve the furnace’s performance while sustaining production capacity at reduced operational costs.
When the 2011 edition of the industrial ovens safety standard NFPA 86 was released, for the first time, safety programmable logic controllers (PLCs) were recognized as logic devices suitable for the safe operation of industrial heating equipment. The safety PLC could now perform the control logic, but it still could not directly control the combustion safeguard systems.
With a firing range of 15,000 to 200,000 MBH, Model FDR(X) combines a windbox, air register, ignition assembly, fuel train, flame-safety control, combustion control, flue-gas recirculation system and forced-draft blower into a packaged unit.
Rockford Systems LLC expanded its industrial safety solution portfolio into the fuel and thermal safety fields by launching a Combustion Safety division. The newly formed division will provide turnkey solutions for organizations that use thermal processes in their operations.
A typical control approach for an industrial fired heater uses global measurements to keep the system efficient and within safe operating limits. Differences in combustion stoichiometry between individual burners, however, can cause global measurements to produce an incomplete picture of the combustion taking place within the heater.
It’s a point of pride that I have every issue of Process Heating ever published cataloged in a small library in my home office. Admittedly, it’s not as tidy as you might find at your local library. I tend to stack issues that I “check out” on the floor in front of the library until it’s time to clean my office. And, while my lazy filing means a career as a bibliophilic cataloger is doubtful, it also provides opportunities for rediscovery.
Combustion and industrial safety, infrared heating and induction heating: All are focuses of a concurrent seminar program presented by the Industrial Heating Equipment Association. The events will be held in Cleveland on September 24-26 and will include IHEA’s fall business conference. The technical seminar series will be held on Tuesday and Wednesday followed by the business meeting on Thursday, all at the Intercontinental Cleveland.
Multi-gas detector can simultaneously detect up to seven gases including, flammable gases, vapors and oxygen. It is suited for use in chemical, oil and gas, mining, pharmaceutical and water treatment applications.
