Fireplace Design - An actual burning issue.
De BISAWiki
Grate and mantlepiece styles have altered but the basic structural aspects of a fireplace have not significantly changed for centuries. The early combination of a big stone or brick beginning with a fireplace built over it changed from the evident fact that smoke rises, as opposed to from a scientific understanding of how a well-designed flue system works. Consequently early wood and later coal-burning fires were very inefficient and it was not until a particular Benjamin Thompson (also called Count Rumford) produced his thesis on the principles of fire design in 1799 that smaller grates and improvements in the internal model of the openings were introduced.
A brick or stone box forms the cornerstone of-the fire. Recess or builders opening or variously called the fireplace opening, it could be set flush with the wall or built out into the room, building a chimney breast. This chimney chest rises through the level of the home, emerging through the roof to form a chimney stack. At the top of the beginning the gather and flue combine to carry the smoke up the chimney. When the fireplace is provided by many fireplaces on different surfaces, it may include more than one flue.
The masonry on the fireplace opening is supported by a lintel or perhaps a brick arch. Old inglenook fire-places used huge oak beams, although a powerful iron strap generally supports an earlier stone arch. Later fire-places could have a straight arc supported by angle iron, and by the twentieth century cast concrete lintels were typical.
A hearth, built from materials including stone or tile-faced concrete, projects out into the room to safeguard the floor from ashes. In many old houses the fireplace was set flush with the floor, though often an one was used to raise the amount. The area within the fireplace opening, the hearth known, is generally level with the hearth itself. Browse here at the link chimney sweep fairfax va to discover the reason for it. Your dog grate for burning wood or coal can be placed on this hearth. Nevertheless, by the century the mass produced cast-iron sign-up grate which filled the opening, had become the fashion.
To perform the assembly, a mantelpiece or mantel or fireplace surround, today since it is often called is suited to shape the grate or fireplace opening. The mantel could be made out of stone, record, marble, wood or cast iron. The walls around it could be finished with wood paneling, or more frequently with plaster, and in some cases the mantel extends upwards to make an extraordinary chimneypiece. Reflected overmantels were presented in the late eighteenth century, and these became the traditional feature of Victorian sitting rooms.
Within this fire an open fire burning wood or coal is a cheerful view, but this romantic picture may soon diminish especially if the fire does not burn properly, if it is your only supply of warmth, as it was for centuries.

For coal and wood fires to burn off well an excellent way to obtain air is required under the grate, as well as a way of escape for the hot gases and smoke. With the fuel safely contained inside the fireplace opening on a grate, free circulation of air is possible and so the fire is not stifled waste ash could fall through the grate. If the fireplace is inadequate or the movement of air is fixed the fire won't func-tion efficiently.
