Method of controlling exhaust gas emissions from an

Abstract A method for controlling exhaust gases emitted from a direct arc furnace melting furnace is described. Prior to cleaning the temperature of the gases is sensed and the arc power is regulated in response to the sensed exhaust gas temperature. Also, the

Cold

2019/11/15The local-heating method in this study can be applied to cold start a PEMFC stack for vehicles. Fuel-cell stacks can be rapidly cold started by arranging a certain number of heating wires in the stack to directly heat a partial region of each MEA and setting the power of heating wires according to the ambient temperature.

How to Warm Dinner Plates — How to Heat Up Dinner

Stack plates in the oven from 140 F to 190 F (60 C to 90 C) for about 15 minutes. Be careful: avoid heating plates up to 175F (80C) as you can burn yourself by touching plates which are too hot. Some ovens have a warmer drawer, specifically designed to keep dishes hot before serving.

How to Heat Up Tortillas and Keep Them Soft?

Microwave: Put a tortilla on a plate and cover it with a damp paper towel.To reheat more than one, alternate tortillas with paper towels. Microwave on high for 30 seconds to one minute, depending on how many tortillas you have. Oven: Preheat the oven to 250 F/120 C. Wrap a stack of tortillas in a damp dish towel and place them in a casserole dish of similar size.

A thermal bonding method for manufacturing

2021/2/11However, the complexity of the method requires a considerable number of advanced instruments and processing, limiting the accessibility of this method for production of Micromegas detectors. In view of these limitations with the bulk method, a new method based on thermal bonding technique (TBM) has been developed to manufacture Micromegas detectors in a much simplified and

Experimental Analysis of the Temperature and Voltage

In the experimental domain of air stoichiometry (4.6-4.8) and air pre-heating temperature (609-612 C), it is shown that air stoichiometry has a deeper contribution to the behavior of the stack. Its effect is linked essentially to the modification of the temperature distribution inside the generator.
