Hot firing

Fig. 1.3. The fire grate, which carries the white-hot fire inside the firebox, must resist oxidation and creep. Stainless steel is best for this application. Note also the threaded monel stays which hold the firebox sides together against the internal pressure of the steam.

Inhaling hot (fire) gases into the lungs will also cause tissue damage to the extent that fatal effects could result in 6 to 24 hours after the exposure. 

A method for breaking boulders used to be putting them in a hot fire, then dousing them with cold water. Why would this fracture the boulders ... 

She had spent the last hour driving through a city that was, beyond the walls of this fortress hub, falling apart. Mogushestvo s armour foundered in sun-hot fires. Surviving tanks turned tail, punishing entire blocks as they went until, ultimately, they ran into further blockades of trucks, moved into position and primed to rob them of their way out. Few would make it clear. 

A major fire erupted in a nonflammable solvents manufacturing unit in a U.S. Gulf Coast chemical complex. A furnace tube in a natural-gas-fired heater ruptured due to overheating. At least 1,800 gallons (6,800 liters) of a combustible heat transfer fluid spilled and burned intensely. Within about 25 minutes, the intense hot fire damaged four levels of structure and associated process equipment. The plant on-site emergency squad quickly and properly responded. However, the price tag for short-lived incident was over 1.5 million in direct property damage and over 4 million in business interruption (U.S. 1979). Fortunately, there were no injuries. [2]... 

Boil mixture over hot fire for at least 2 hours. Small grains of salt will begin to appear in the solution. Scoop these out as they form, using any type of improvised strainer (paper, etc.). 

Incineration of waste offers an advantage. Less land is ruined in disposal of the solid ash left after incineration. In some cases, the heat from incineration has been used to generate electricity. Despite advantages over landfills, simple incineration with or without electrical generation has not proven to be a quality method of solid waste disposal. Trash is a poor fuel so it does not produce a hot fire when it... 

Then take out all the faeces which remain in the retort, and arc blackish like unto soot, which feces are called our Dragon, of which faeces calcine one pound or more at your pleasure in a fervent hot fire, in a potter s or glass-maker s furnace, or in a furnace of vent (or a wind furnace), until it become a white calx, as white as snow which white calx keep well and clean by itself, for it is called the basis and foundation of the work, and is now called Mars, and our White Fixed Earth, or Ferrum Philosophorum. 

Unless it was a very hot fire such as one fanned by a high wind, some accelerant almost always soak into the wood, under a sill, below the carpet, into a crack in the cement, under floor tile, into the stuffing of a car seat, or into the ground, and remains unbumed or partially unbumed.. 

With God s blessing, here is the treatment Take the noble stone. Deposit it in the cucurbit and alembic. Separate its four elements, which are water, air, earth, and fire. They are substance, spirit, soul, and dyeing. When you have separated the water from the earth and the air from the fire, keep each one apart in its own vessel. Take the dregs - the sediment - at the bottom of the vessel. Wash it with hot fire, until the fire has removed its blackness, and its coarseness and toughness have disappeared. Blanch it carefully and evaporate the superfluities of the humidities concealed in it. It will thus become white water, which contains no darkness, dirt, or disharmony. Then, turn to those primary elements that are distilled from it. Cleanse them, too, of blackness and disharmony. Wash them repeatedly and sublimate them, until they become fine, subtle, and pure. When you have done this, God has given you success. 

The stable doors had been all but consumed by the eerily hot fire. Their remaming planks sagged and twisted on the glowing hinges, then lurched onto the cobbles with a loud bang.

In the batch process, it typically takes a day or two to load a typical-size concrete kiln with about 50 cords of wood. When the fire is started, air intake ports and exhaust vents are fully open to draw in enough oxygen to produce a hot fire. During the week-long burning period, ports and vents are adjusted to maintain a temperature between abont 450°C-510°C (840 F-950°F). At the end of the... 

According to this theory, water (moist and cold), air (moist and hot), fire (dry and hot), and earth (dry and cold) combine in various ways and proportions to generate all of the materials found in the universe. 

The lighting of fired heaters has the potential to create an explosion. Two issues are of particular concern. The first is that the firebox is filled with a flammable mixture of hydrocarbon gas and air (oxygen). If a burner is ignited, an explosion will occur. The second concern is that a furnace is operating normally, and then the fuel gas supply fails thus causing the burner flames to go out. If the fuel gas supply is then restored, an unbumed mixture of gas and air can enter the hot fire box and ignite.
