Dutch oven

When used for ceramic heating, furnaces are called Idlus. Operations include drying, oxidation, c cination, and vitrification. These Idlus employ horizontal space burners with gaseous, hquid, or solid fuels. If product quahty is not injured, ceramic ware may be exposed to flame and combustion gases otherwise, muffle Idlus are employed. Dutch ovens are used frequently for heat generation. 

The next stage may best be described as a primitive hot-filtration process. Two members of the village sit across the front of a simple fire resembling a Dutch oven, holding between them a bag about 30 feet long and about two inches in diameter. The lac inside the bag melts and, through one of the operators twisting the end of the bag, the lac is squeezed out. The lac is then removed from the outside of the bag and collected into a molten lump which is then stretched out...

Heat the oil in a Dutch oven. Add the rice and cook, stirring occasionally, over medium-high heat for about 5 minutes. Add the leeks, chilies, bay leaf, 1 teaspoon salt, and the 3 cups stock or water. Give a stir, cook for a few minutes, then lower the heat. Cover and simmer for 20 minutes. 

Varied boiler firing configurations are found in hog fuel boiler applications, including dutch oven, fuel cell, spreader stoker with traveling or vibrating grates, and cyclone stoker types. As stated previously, the spreader stoker is the most widely used of these configurations. Spreader/stoker boilers in the pulp and paper industry often have an air swept spout added to the front of the boiler to feed bark down on top of the coal.14 Wood is puffed at one-...

These principles underlie the operation of smokeless furnaces and mechanical stokers. Stokers vary greatly in maintenance cost and in the associated cost of maintaining brickwork. In large plants, they save labor. A modern form of the old Dutch oven extension furnace, will give little smoke even when hand fired, if the furnace is not driven hard. The flames are kept hot, because they do not strike the boiler surface until combustion is complete. 

Wood.—Sohd wood fuel prepared for the purpose, is occasionally used under boilers in the Northwest. Split fir at 3 per cord, delivered, is about equivalent economically to the local low-grade coals at 2.20 per ton. Refuse wood fuels (slab, edgings, chips and sawdust) are more frequently employed. Suitable methods of feeding must be provided fine particles may be blown long distances. If the moisture content is large, a special furnace on the Dutch oven principle may be found necessary. Woods contain very little ash. 

It is practical to suspension over-fire a dutch oven or grate system with residues but characteristically higher emissions from suspension firing must be considered. The higher percentage (4-6 ) of low-melting ash in ag-residues poses special grate problems vis-a-vis wood at 1. ...

Dutch Oven. A simple furnace of small size and usually fired with solid fuel it can be constructed outside a newly-built furnace, for example, and used as an air-heater for drying-out and warming up (cf. DUTCH kiln). 

MAKE A ROAST. It can serve as a foundation for a week s meals. Bake a turkey or two chickens, pop a brisket in the slow cooker, or make a pork roast in a Dutch oven. Eat it right away for dinner, then refrigerate or freeze the leftovers for future sandwiches, stir-fries, salads, and soups. 

Heat the vegetable oil over medium-high heat in a Dutch oven or heavy ovenproof pot with a lid. Brown the chops well, about 2 minutes per side, adding a little more oil if needed. 

To braise meat, you ll need a slow cooker, Dutch oven (a large, heavy cast-iron pot), or other heavy pot with a tight-fitting lid. If using the oven (with the heat set at 325 degrees Fahrenheit), make sure your pot is ovenproof You ll still need to use the stove for the searing step (see following). Either way, the lid is key because the steam in the pot helps cook and tenderize the meat. 

Pour the oil into a medium-size Dutch oven and heat on the stovetop over high heat. Working in batches, carefully cook the meat until each piece is browned. 

Once all of the beef is cooked, pour in the broth. With a wooden spoon, scrape the sides and bottom of the Dutch oven to loosen any cooked-on bits. 

Layer the beef cubes back in the Dutch oven and add the boiling water. Stir, then add the vinegar, Worcestershire sauce, brown sugar, onions, celery, and bay leaves. Reduce the heat to low, cover, and simmer until the meat is fork-tender, about 3 hours. 

Deep-fryers are very handy, hut not crucial. There are electric fryers that look like big stockpots with a plug, restaurant-style fryers for countertop use, and stovetop deep-fryers fitted with a lift-out basket. These can he good investments if you plan on doing a lot of frying, hut to avoid the expense, you can simply use a large pot or Dutch oven and scoop out fried foods with a slotted spoon.
