Fireplace stoves
The main task of modern heating appliances is to create comfort and coziness in apartments and country houses. How interesting and beneficial are the furnaces of a fireplace type for owners of country houses and cottages?
Let's say frankly that sufficiently powerful and functional stove-fireplaces have a high efficiency (up to 90%), easily installed installation and trouble-free operation. One fuel deposit for the fireplace type furnaces provides a continuous cycle of burning for 12 hours. A variety of models of fireplace ovens can have the following design:
• Woodburning stoves
• ovens - fireplaces
• heating furnaces
• heat storage tanks.
The most interesting are heat storage tanks. The increased interest will be explained by the following qualities of heat-storage furnaces:
• stylish modern design
• environmentally friendly fuel combustion
• safe temperature and composition of the exhausted combustion products.
It is for these criteria that it is recommended to choose fireplace heat-storage furnaces for the home. However, it is quite difficult to make a choice of heating equipment from the photo of fireplace stoves. On the basis of what data can you choose the right heat storage house for a fireplace?
What are heat storage tanks
fabrication material for carcass and cladding
From the numerous colleagues of fireplace stoves, the heat-storage furnace differs in its characteristic type of cladding. This is a gray stone - talcomagnesite or talcum chloride (Tulikivi). For the first time the rock began to be used for stove and fireplace use in Finland. The natural data and qualities of the rock allowed the accumulation of a significant amount of heat, preserving it due to the facing of the furnace.
At the same time, the heating time with the use of furnaces equipped with talcchloride increased to 8-10 hours. It should be noted that the radiation background inherent in materials such as marble and granite does not exist for talcomagnesite. The presence of harmful impurities, as well as the radiation background of the stone, must be fixed by appropriate certificates. Therefore, when choosing, it is necessary to pay special attention to this fact.
accumulator of injector type
According to the laws of heat convection, the transmission of heated and warm air in the room is carried out by means of an interlayer of air distance between the outer shell of the heat storage chamber and the furnace insert.
Natural and artificial convection of warm air is carried out using a fan. The peculiarity of heat-storage furnaces is their rapid heating and slow cooling. Most furnace models, such as fireplace oven Tulikivi, The equipment checked during long-term operation is used.
The well-designed design of the heat-storage furnace makes it possible to distribute heat evenly throughout the room. This is an injector-type heat accumulator, which includes chimneys and adjoining heat-accumulating plates made of soapstone.
Here, heat accumulates and radiates into the space of the room. A small amount of firewood (up to 10 kg) and a two-hour warmth of the furnace will provide a room with dry heat for 18 hours.
It should be noted that the heat capacity of talcchloride is 3 times higher than that of oven bricks, therefore, compared to oven bricks, Tulikivi fireplace furnaces cool much longer.
counterflow principle
In furnaces of a fireplace type and heat-accumulating furnaces the circulation of hot air is realized according to the principle of counter flow.
Theoretically and practically this means that the descending heated air on the outer walls of the fireplace creates conditions for convection of cold air. Thus, the transfer of cold air quickly increases the room temperature.
In addition, the storage frame of the storage chamber is made of plates cut in a certain way, namely across the fibers of the stone.
Plates for the outer lining of the stove are sawn along the fibers of the stone. Thus, an obstacle is obtained for the transfer of heated air and heat is accumulated. Optimum selected thickness of the furnace frame (90 mm) creates a peculiar microclimate for thermal energy, taking into account the minimum fuel consumption.
double combustion technology
Special technology of double combustion for furnaces of accumulating provides high efficiency. For ordinary fireplaces, it is characteristic that fresh air enters the furnace through the grate bars. The flow rate of the warm gas is significant, the gas does not have time to burn completely, thereby lowering the efficiency of the fireplace. In storage ovens, this problem is solved by slowing the speed of fresh air.
Such a slowdown is due to the selection of the cross-section of the holes in the working grates. On the three internal sides of the furnace are installed ceramic panels, equipped with additional openings for fresh air. Not having time to burn out the gas from the grate zone is afterburned by incoming air from the middle part of the furnace. Innovative dual-combustion technology solves one more problem at the same time. The release of carbon dioxide from the battery-type furnaces is minimal. By the way, when selecting, it is necessary to pay attention to the fact that the percentage of CO2 emissions has a sparing ratio.
assembly and installation of storage ovens
As practice shows, the assembly and installation of storage stoves with their own hands does not cause complications, and even more complaints. Finnish heating devices of TULIKIVI brand are made of plates with geometry, which is calculated by software and cut into CNC machines, the minimum error is ± 0.3 mm.
The plates are ground with chamfering, ensuring reliability during transportation. In addition, the ease of assembly is due to the fact that the fastening element in the assembly is steel staples (clamps).
In the delivery set of the manufacturer there is also a package with liquid talcum-magnesite for subsequent filling of the joints.
Model range of storage ovens
The model range of accumulating furnaces is represented by straight and angular fireplaces. The possibility of location in the house involves the placement of stoves near the walls and in the corners.
The area of the furnaces is insignificant and amounts, depending on the model, to about one square meter. The identity of the processing of all the outer walls of the stoves - fireplaces allows them to be placed even in the center of the room. There are a series of lightweight furnaces designed to install and place floors on floors that have little bearing capacity.
Particular delight is caused by corner stoves - fireplaces. The minimum occupied area of corner furnaces allows to enter such furnaces in any interior of a country house. The shield panel of the firebox with the glass bay door can be rotated by an angle of 45 degrees, relative to the wall.
The functionality and stylish design of the storage ovens, as well as resistance to significant temperatures, create all the prerequisites for the correct choice of a heater for a country house or cottage.
