the Fire chamber of furnaces
(A part 2)

To avoid a poisoning with carbonic oxide, it is not necessary to heat the furnace for the night. When for a fire chamber use coal or peat, in a smoke latch it is recommended to drill an aperture in diameter of 10-15 mm through which gases will be taken away skopljajushchiesja in the furnace.

Coal put in a furnace fire chamber, heated-up fire wood. On burning charcoal fill coal a layer of 50-60 mm and as soon as it will inflame, fill up coal, having finished a thickness standing approximately to 150 mm. To fill thicker layer does not follow. In process of a burn-out coal fill up, keeping a thickness of a layer of 150 mm.

So, we have in detail enough considered oven works, and it is not casual: non-observance of recommendations at a laying can lead to bad work of the furnace.

It is necessary to remember that zolnik should correspond on the size to a grid-iron lattice, after all dverka it serves for regulation of giving of air in the furnace. At a lack of air fuel burns badly, and at surplus - warmth as air cools the furnace from within is lost.

Crude air, as well as crude fuel, reduces draught of oven gases in a chimney. In this case it is recommended to heat at first the furnace a small amount of dry fuel. Hot gases will remove dampness from the furnace, and draught will improve.

Draught Strengthening is promoted by nozzles on the chimneys made of a roofing steel. Here are good every possible fljugarki and deflektory, i.e. The devices changing the position under the influence of a wind so that an aperture for an exit of gases from the furnace it has been directed downwind and any stream of a wind could not hit about an internal surface of a pipe or these devices.

Furnaces badly get warm because that oven devices leaky close the furnace or there were cracks in seams of an oven laying. Non-uniform warming up of the furnace happens is caused by infringement of internal partitions. In this case it is necessary to disassemble one wall of the furnace, to check up partitions, to correct them and to put the disassembled part, without leaving even the slightest cracks.

When furnaces establish on wooden to a floor, a laying often conduct on shantsah, i.e. On columns from two numbers of a bricklaying for all width of the furnace. The distance between shantsami 7-13 see From above they are blocked by two numbers of strictly horizontal bricklaying which is podom furnaces. SHantsy form an air layer between a floor and podom furnaces that promotes aeration and space cooling. Furnaces on shantsah build without blew more often.

As it has been told, the deal floor is dangerous in the fire relation, therefore a floor under the furnace often dim the felt soaked in a liquid clay solution and cover from above with the roofing steel painted from two parties.

In summary it would be desirable to remind that strong coupling of a clay solution with a bricklaying probably only at good saturation of a brick by water (approximately at 6-10 time is stronger, than at slightly moistened). The brick should be high quality to sustain long vymachivanie in water. A thickness of seams no more than 5 mm. The solution is necessary for filtering through a fine sieve. Long drying of the furnace Besides, is required.
