That laser preheating is able to correctly heat the fuel.

For one thing, it needs no preheating.

This furnace operates at a high temperature by using regenerative preheating of fuel and air for combustion.

Adequate preheating and sufficient coals should guarantee that the grill is hot when it is time to cook fish.

Fritting, and the preheating of crucibles may have occurred in the upper areas of the main furnace.

Like a microwave oven, it requires no preheating, and it cooks food in about a third the time of a standard oven.

Hot blast refers to the preheating of air blown into a blast furnace or other metallurgical process.

The introduction of heat recuperation for the preheating of the air of primary and secondary combustion.

Cavities, pores in the solder, can be caused by contaminated surfaces, insufficient flux, and insufficient preheating.

Burning filtered WVO directly is somewhat more problematic, since it is much more viscous, but it can be accomplished with suitable preheating.

In regenerative preheating, the exhaust gases from the furnace are pumped into a chamber containing bricks, where heat is transferred from the gases to the bricks.

So, although we noted that the temperature gauge on the hood registered between 375-475 degrees Fahrenheit, during the initial preheating, the radiant temperature within the cookbox was actually a good 100 degrees higher.

I imagine you can change this situation by inserting a flat, heat resistant stone (like a ceramic tile), on the bottom rack into your oven and include that in the preheating of your oven.

It was very simple, efficient, and reliable in operation, with the minor disadvantage that the vaporizer required preheating for a few minutes before the engine could be started; when running, it retained sufficient heat to ignite the injected fuel.

This can even be connected to the car or truck's cooling system to save space and weight, but also to provide a condenser in the same location as the radiator and preheating of the water using heat from the engine block.

In addition, many of the viable control strategies for HCCI require thermal preheating of the charge which reduces the density and hence the mass of the air/fuel charge in the combustion chamber, reducing power.

Gases with an HS content of over 25% are suitable for the recovery of sulfur in straight-through Claus plants while alternate configurations such as a split-flow set up or feed and air preheating can be used to process leaner feeds.

(Recently, even this has become obsolete as Nernst glowers have been largely replaced for this purpose by silicon carbide glow bars or "globars" [1] which are conductive even at room temperature and therefore need no preheating.)

Preheating is generally not necessary for mild steels less than one inch thick, but low alloy steels may require preheating to slow the cooling process and prevent the formation of martensite in the heat-affected zone.

This fuel is sometimes known as Bunker B. It may be obtained from the heavy gas oil cut, or it may be a blend of residual oil with enough number 2 oil to adjust viscosity until it can be pumped without preheating.

Avoiding turnarounds requires the meltshop, including ladle furnaces (if any) to keep tight control on the temperature of the metal, which can vary dramatically with alloying additions, slag cover and deslagging, and the preheating of the ladle before it accepts metal, among other parameters.

About an hour, including the time it takes to preheat the oven, is needed.

About 30 minutes before serving, preheat a grill to very hot.

Three to five days ahead, preheat the oven to 190 degrees.

To make them, simply preheat the oven to 400 degrees.

But these chores can also be done as you preheat the grill.

The entire process takes less time than preheating the oven.

When ready to serve, preheat the oven to 375 degrees.

One is to preheat the air to 300 degrees Fahrenheit.

About 20 minutes before serving, preheat the oven to 400 degrees.

To make the chicken: Preheat the oven to 375 degrees.

This is where I came in, because the oven was to be preheated to 400 degrees.

If using a baking stone or tile, preheat it for 30 minutes.

If using fresh peppers, preheat an oven to 350 degrees.

Light a charcoal barbecue, or preheat a grill to high.

Note that oven must be preheated at 450 degrees a full 30 minutes.

Meanwhile, to make the soup, preheat the oven to 425 degrees.

One hour prior to serving, preheat the oven to 300 degrees.

The knock on the door came just as I was preheating the oven.

About a half hour before the beans are finished, preheat the oven to 350 degrees.

Oven and stone must be preheated to 450 for a full 30 minutes before baking.

They preheat the potatoes to make them easier to handle and peel.

To prepare the tomatoes, preheat the oven to 250 degrees.

The function of the boiler is to preheat the oil used in the ships.

Turn on the oven and preheat it to four-fifty, will you?

If they are to be broiled, preheat the broiler to high.
