At the top of the firebox beneath the arch is "serpentine", which heats water for washing.Day of giving greater strength casing stove is enclosed in a metal frame.The sweat lodge offices of large baths, where the water is prepared centrally in the boiler, the coil can not be installed.
steam obtained by spraying water through a specially arranged box-hot cobblestones.Thr
When calculating sauna ovens recommended to adhere to the following data:
1. The mass of stone and pig iron per 1 m3 volume of the sauna 60-62 kg, 80% rock and 20% of pigs.
2. For a couple of hot water (45 - 50 ° C), are thrown into the stove, taking the rate of 6 liters per 1 visitor that is approximately equal to the volume of one bathhouse gang.
most convenient to use the stove continuous with electric heating - heater.Electro produced by the plant of electrical equipment, have considerable power (over 10 kW) and designed for use in public baths.Development of production of low-power electric units, will undoubtedly lead to their popularity.
Power heater depends on the size of the sauna, the quality of the thermal insulation of its walls and the atmospheric temperature.Roughly one can assume that for 1 m3 volume of the sauna is the power consumption of 0.7 kW.This means that with a ceiling height 2-2.2 m for 1 m2 of heating steam room requires 1.4-1.6 kWh of energy.
simplest elektrokamenka is electric gated, which put a metal box with stones.If the power of a heater is not sufficient for a good air heating, it is possible to use a second electric gated setting her massive piece of metal to improve heat dissipation.
heating.The heater prefabricated heating stones made tubular electric heaters (tags, heating elements) included in the thickness of the bottom stone backfill.More sophisticated are the heater, in which the ventilation air does not pass through the thickness of the stones, and freely flows around a stone filling between two covers and heated for an additional electric heater.At the same time the stones are heated to 350-450 ° C, and the air - up to 100-120 ° C.
increasing the number of stones in the filling, you can increase the stock of accumulated heat to produce steam.For the sauna with dry steam mass of stones may be minimal.Many foreign construction elektrokamenok provide for changes in the mass of stones is 10-30 times (for example, the average size of the heater - from 5 to 60 kg).
Such a system of separate heating and air stone backfill with the regulation weight of stones is called a system of soft heat.An advantage of this system is the fact that the air does not contact the hot stones and acquires unpleasant smell of burning of dust contained in the air constantly.
For convenience and safety of using the stove must be equipped with temperature controller, safety temperature limiter, which switches off the electric heater when the room temperature to 140 ° C and a timer, which turns off the electric heater after the set time of continuous operation (up to 5 hrs.).
furnace-heater for solid fuel
furnace size 40x50x75 cm, in the steam room of 10 m3 furnace generates temperatures up to 140 ° C oven
feature: the secondary air into the upper zone of the combustion chamber through the slots in the housingand flue gases pass into the channels around the hopper for the stones and out the chimney through the front opening.The furnace has double side walls, the gaps between them are the channels for heating and air circulation.
compact furnace heater
compact furnace continuous heater can be made of kiln-laundress.The tank instead of water charged stones and the water can be heated in a bucket, mounted on the stones.Oven-heater can be connected to the chimney with a steel barrel filled with stones, then turn heater with a supply of heat in the rocks and hot water.The lack of an oven: heat radiation through thin walls are thin.To eliminate this disadvantage can be achieved by imposing brick exterior of the furnace while leaving a gap for air circulation.
Thin heater short-lived.Apply homemade furnace welded from sheet steel in the thickness of 3-5 mm.
heater with built-in water tank
furnace size 50x60x80 cm, height 30-40 cm of the furnace, the temperature in the steam room kept at 80 - 100 °, the sauna area should be up to 12 m2.Mass loaded 150kg of stones.
Improving the efficiency of the furnace. To fully utilize the heat discharge is passed through a stone chimney damper.To accelerate heating stones tray as they operate with the inclined walls of the hopper, washed by hot flue gases.
most convenient and practical furnace with double walls, the space between them is used as a hot water tank.It is possible to connect an additional capacity of the tank with water, set next to the stove.Double-walled furnace heats the bath by convection air.To enhance convection walls operate with an air gap, an open top and bottom.
Metal furnace heater continuous room with kitchen stove
Dimensions stove 40x50 cm, the temperature in the steam room is maintained at 100 ° C.Such ovens take up little space, quickly raise the temperature in the steam room, and you can wash it in 30 minutes after the start of the furnace.They are hygienic, safe, do not require frequent maintenance.Most of the baths on the garden and suburban areas equipped with such stoves.
design. Construction furnaces diverse.These furnaces can be combined with furnaces, dryers, cooking stoves.The oven is made of sheet metal waste.The upper part of the firebox of the furnace communicates with the kitchen stove ash pan, which is heated and also from the kitchen.The stove body mounted on both sides of the open flame tubes with stones.In the oven put a tank with a crane and pipes for water supply in the flues.
In order not to get thermal burns, canopy closed metal shield of steel roofing.This room bystrodeystvenna.
Heating and disadvantages.If sink kitchen stove is no need, then lay the wood directly into the furnace-heater.Wood consumption less, and heated bath even faster.As with other metal stove a continuous oven required heat does not accumulate.It heats up quickly, and rapidly cooled, so we need to constantly underlay firewood.The need for a continuous furnace is inconvenient.
Combined oven. metal furnaces have a small heat capacity and do not create the necessary softness and uniform heating of the body.It is preferable to use the heat capacity of the ovens, stoves of brick, can be separated from the furnace chamber wall stones, then the furnace can burn in continuous and batch operation.In this case the oven is called combination.
furnace-heater combined action
stove differ from the combined action of continuous furnaces higher heat capacity.They allow you to enjoy the bath after a single furnace and at the same time, if necessary, allow a continuous furnace during bath procedures.Collect the required amount of heat provided by a massive brick walls and a large mass of rock backfill.
In principle, such a furnace may be a metal enclosure.However, the heat capacity of the metal body is small.To be able to use the metal in the furnace batch must increase the mass of stones so that for every 1 cm 3 volume of the sauna accounted for at least 15 kg stones.This leads to a complicated construction and an increase in size of the furnace.
Almost all furnaces combined actions make brick.The main distinguishing feature of - the presence of an impermeable partition between the firebox and the stone chamber that produces steam without stopping the furnace.As used impermeable baffle iron plate, cast iron boilers are welded from sheet metal, thin-walled partitions quickly burn or deform under the influence of high temperatures, which can lead to the destruction of the furnace and cause a risk of fire.
It is best to use iron plates designed for stoves.They are deaf and with openings for the burners.These holes are not a hindrance when using the oven.Moreover, with the burner plate can be used to close the chamber with stones on.After removing the burner plate through the holes, you can splash water and produce steam at the right time.Thus, it is possible to simplify the structure of the furnace, eliminating the door to the steam chamber.
surface of the box and the boiler is washed by the hot flue gases, and the stones are heated so quickly.Immurated firebrick firebox allows coal to stoke the furnace or a burner for liquid fuel.The main drawback of these furnaces - no heater.Installing the water tank or hot water pipes - register - complicates their design.
