Heating stoves long burning - maximum heat with minimal costs

How do the heating furnace with wood

Almost all wood-fired ovens operate on the same principle: the furnace laid the wood, which quickly burned by heating equipment itself, the walls of which is given warmth to the room.As a result, the temperature of the room rises quickly, but also drops quickly, so you must constantly add fuel.

As a heating furnace with wood

usually begin to ignite the fuel at the bottom.The fire quickly rises, the wood burns quickly, and there are only embers.Therefore, to maintain the flame constantly have to throw to them.A distinctive feature of the heating units long burning is able to receive heat for a long time without the need for a permanent bookmark in firewood furnace.These gaps can be up to 20 hours.This is achieved by the fact that the combustion process proceeds in the opposite direction, i.e.downwards, while oxygen is fed doses limited to a certain place, and so the thrust decreases fuel burns slower.

Classification of long burning stoves

These heaters come in several types: air and water circuit.By appointment, they are divided into:

  • Heating:
  • for baths;
  • Cooking;
  • heating and cooking;

Make furnace of steel, cast iron or brick.The fuel used:

  • wood;
  • Coal;
  • sawdust, etc.

Classification of long burning stoves

long burning stoves with a water circuit

One of the most popular models are the wood-burning oven with a water circuit.Make such products from iron or steel and are used as the main heating source, and optional.

principle of operation of such devices is similar to the principle of the solid fuel boiler.Steel water heat exchanger located inside the structure in the furnace or in the flue.In operation, the furnace is heated and water is passed to the radiator.Thus, there is a uniform heating throughout the perimeter of the room.

advantages of such long burning stoves are:

  • Possibility uniform heating of one or more rooms a large area;
  • Economy through the use of accessible and inexpensive fuel;
  • saving, since this equipment does not require an electricity

gasifier furnace with wood and features

from all other gas-generating furnaces distinguished by the presence of not one but two combustion chambers.The lower chamber is used as the gasification chamber, which limit the access of oxygen and the wood do not burn and smolder.Released during smoldering gas is supplied to the upper chamber and is burned completely and already heats the air, which goes through a duct into the room and warms it.

The main advantage of this equipment is an economical, since the design of the unit allows for a minimum consumption of gas, enough to operate for a long time - up to 16-18 hours.

The price of such a furnace acceptable enough, but having certain skills, you can make it, and with his own hands.To do this:

  • sheet metal is welded, double chamber housing the size you want;
  • connected steel tube, which will serve as a regulator of airflow to the design;Additionally
  • between cameras mounted the grate, and the input and output - power regulators and a gasifier;
  • to the body is welded heat exchanger consisting of the lower and upper tube to draw the cold and hot air return.
  • body surface treated refractory paint

Buy long burning oven ready or build it yourself depends not only on financial opportunities, but also on the characteristics of its use.
