Enhancing Furnace Thermal Efficiency by Adjusting Fuel Temperature

Thermal Energy Storages in Vehicles for Fuel Efficiency Improvement

Feasibilities of heat and cold storage technologies for vehicles were discussed for improvement of vehicle fuel efficiency. Energy performance of a plug-in cold thermal energy storage system, in which ice slurry is produced at a stationary chiller and charged into a tank in a vehicle for cabin and cargo cooling, was discussed. Energy balance of the plug-in system was compared with onboard heat ...

Thermal Analysis of Induction Furnace

Induction heating furnaces are employed for vacuum distillation process to recover and consolidate heavy metals after electrorefining operation. Induction heating furnaces of suitable heating rates are required to be developed for this purpose. Hence it is planned to set up a mock-up induction furnace which will simulate the conditions to be realized in actual induction heated vacuum distillati...

Enhancing the Luminescence Efficiency of GaSb-Based Dilute-Nitrides by Rapid Thermal Annealing

It has been shown that gallium antimonide (GaSb)-based dilute-nitrides display improved photoluminescence (PL) with in situ annealing in the molecular beam epitaxy (MBE) growth chamber under a Sb ambient. This improvement in luminescence efficiency translates into improved performance of optoelectronic devices, such as lasers, where this will lead to a reduction in threshold current densities. ...

Temperature Control of EDC Thermal Cracking Furnace with a Coupled ODE and 2D-PDEs Model

This paper presents a new control technique for the EDC thermal cracking furnace modeled by sets of ordinary differential equation (ODE) and 2D-partial differential equations (PDEs). The dynamics of coupled 2DPDEs-ODE model have been divided into 2 subsystems, set of state variables of the internal and external cracking coil. With the concept of input-output (I/O) linearization, these inner and...
