Types of furnaces for home and garden - say "no" to colds

Types of furnaces for home, a visit to the past

in different countries and different story furnaces, although, in general, have in common they all have: a niche for fuel, the chimney, in the more modern - the ash pan and the valve in the pipe.Separated by furnace into three kinds: cooking, heating and cooking-heating.Initially it used throughout the third type, the universal center - oven made of stone, with a wide hearth and a spacious opening is large enough furnace, where carried out, and cooking on skewers and boilers, hanging on a hook in the roof fixed.But then began to happen appreciable change, for example, we have the famous Russian oven (also the cooking and heating), but without the pipe flushing "black."In the 18th century the population of Europe has spread "Swede" is convenient because the cooking of it was located in the kitchen and a room for a built-in wall heater warmed "shield."At the same time Europeans began to use the "Dutch" (for the most part purely for heating), and over time, ingrained in St. Petersburg.By the way, here and there hotbeds used today.

Every century furnaces have evolved rapidly all, they developed no longer the master of the people, and experienced engineers, some were from the nobility, and even military ranks have, such as General Amos.Oven, created last and named after him, is heated by the Winter Palace, making it the most severe frosts quite summer temperatures. Today some types of furnaces for home almost unusable due to large size (oven Amosov) or low efficiency (normal hearth) .However, for example, furnace chimney is quite good for a small cottage or country house: large entrance door, bottom compartment has a direct channel of the chimney, the upper chamber has a connection pipe overlap flap.When the doors are closed and the shutter you get an oven with a decent heat dissipation, and is open chimney flap and top of the camera and in front of you has a brick fireplace, barely heated space, but creates comfort.Another option similar combination - a stove, however, there is already a slightly different design, a fireplace attached to the furnace and can give comfort at the same time heating the room, and in the presence of niches and cooking food cooking can be done in parallel.

furnaces for heating the house - the whole thing in the walls

The center is able to maintain an acceptable temperature in only one room, a Russian stove is designed to house up to 25 square meters, three or four rooms (respectively, one or two should bebushing).Why such difference?All the matter in the walls, or rather, in their thickness. thinner masonry oven, the faster it heats up and cools down just as quickly .Accordingly, the thin-walled furnace have to sink all the time, which is quite wasteful.Let us consider those options that allow you to save a little on fuel, to those can be attributed furnace heat accumulating the most simple design and sophisticated air heater and convection heating systems.Let's begin with a simple.Furnace, heat accumulating, such as Russian, "Dutch" and "Swede" (quite an international list) are made with the use of brick, with masonry can be prepared in advance for plaster, thick layer which can store heat longer.To trim are also frequently used tiles and tiles.

Overall, brick copes with the accumulation of heat, but if top to put tile, heat will be a little longer, especially as the ribbed surface of the back of the tiles greatly increase the heat radiating area.In the past, for the same purpose used tiles - small tiles of fired clay to ringing, very reminiscent of a modern tile.For example, Russian furnaces efficiency for heating houses is 68%, this is equivalent to the full impact of modern thermal power station operating on solid fuel."Dutch" and "Swede" work somewhat differently in the thickness of the housing hides several serially connected vertical channels through which heated air moves countercurrently other words, the first riser, then at the following knee downlink and so on.

walls Warming turns long, followed by long-term impact of heat, if the thickness of the masonry large enough heat accumulates up to 36 hours at a low cost fuel.

furnaces particularly complicated design, for heating

Heating furnace air heater types have been around for a long time, creating the Winter Palace heating system General Amos was an improved model of the heater, but it is known that such a method of heated palaces in ancient times.The furnace design is quite complex, it is a kind of two buildings, one of which is located inside the other.Moreover, the external can be a brick, and the inside - the metal, there are also all metal model covered with a tiled stove, fastened by special loops without solutions.Features air heater furnace lie in almost absolute tightness of the furnace, whereby once downloaded firewood in the combustion process is completely alien to them processed into a gaseous state.For this purpose, in the upper part there is a special afterburner chamber where just burned gas produced from solid fuels.Ashtray in such furnaces is no longer needed.

With such an economical wood burning interior decorating drovnitsa for the fireplace can be filled very infrequently, so that does not need several times a night to go out into the cold for logs.Benefit heater there and it seems to be out of competition, but the opponent he is still there, and this fire, however, the convection type.Inside the walls of this chamber there is a vacuum, the camera covering the whole fireplace or its upper part.Return air enters through the holes located at the bottom of the camera, and then the heated air masses rise up to the special ducts, distributed throughout the room even flow.If you provide a fireplace glass doors, fully insulated from the furnace environment, you can achieve an effect similar to what is happening inside the air heater furnace - full and very slow burning wood.However, the ash pan convection fireplace is still needed, the fuel is not burned it to a gaseous state.
