Is there any repair of brick stoves "in the teeth" of homemade products?
As the services of oven masters are quite expensive, many owners of brick ovens try to master the basic principles of their repair independently. Of course, everything depends on the complexity of the breakdown.
There are three types of repair work:
- preventive;
- partial;
- capital.
Preventive maintenance is to maintain the cleanliness and order of the brick kiln throughout its life. The owner himself follows the integrity of the movable and immovable parts of the unit, relieves his "insides" from ashes and soot, eliminates small defects in the laying of bricks( cracks, chips).In this case, the help of the profile master is not needed.
Partial repair involves the replacement of one or more parts of the furnace. It is easiest to update its easily removable parts: grate, cast-iron plate, water tank. But the work to replace or strengthen the furnace door( flap) will not be carried out by everyone. Here you need to be able to disassemble the brickwork around the damaged part and restore it again. Partial repair is quite possible to the owner of the furnace, which owns the minimum skills of a mason.
Overhaul of a brick stove is the most laborious and laborious kind of work. Without the help of an experienced master, you can not do. During the elimination of serious problems, a partial or even complete disassembly of the unit is required. To the same type of repair work is the modernization of the furnace: re-equipment for a different type of fuel, expansion of the firebox and chimney.
With the help of our tips, you can very well carry out a preventive and partial repair of the brick oven, but you must entrust the capital alteration to the specialized specialist.
What is the most common reason for repairing a brick oven?
After analyzing the statistics of their calls to the client, the masters identified the main causes of the breakage of the brick brazier:
- Incorrect operation of the stove. Most often, the owners sin in the incorrect placement of fuel in the combustion chamber: the logs rest against the back of the box and burn it. Dirty and wet firewood is also harmful to internal parts of the heater.
- Lack of proper maintenance of the stove. If you do not clean the chimney and the firebox in time, the brazier will be covered from inside with a thick layer of soot and soot. Dirt clogs the outlet ducts, significantly reduces its heat transfer, damages the brickwork.
- Incorrect stove assembly. Weak foundation, violations of cutting rules for laying bricks, erroneous proportions of the chimney, firebox - all this is serious miscalculation, requiring complete disassembly of the unit. In fact, it is cheaper to destroy the old one and build a new full-fledged home.
- Wear of fittings. This reason is quite understandable - there is nothing eternal. The harder the operation, the more frequent replacement of components. For example, the most delicate and quickly wearing model is a stove-sauna heater, exposed to simultaneous exposure to fire, heat and moisture.
How can I repair a brick oven?
So, let's consider the 3 most popular breakages.
No draft in the chimney.
There may be several reasons for this defect. Firstly, if you have not used the oven for a long time, a "plug" from the cold air is formed in the chimney. Secondly, the canals are covered with shards of damaged brick masonry. Thirdly, they are simply clogged with soot.
Your actions: clean the bottom of the chimney through the furnace door. If everything is in order, lay the paper at the beginning of its pipe and set it on fire. The characteristic loud buzz and the subsequent appearance of normal traction testify to the removal of the cold "plug".Did not it help? Then it's time to go to the roof! Using a ruff with a weigher, carefully clean the chimney and try again to melt the oven.
Small cracks on the brick walls of the furnace.
The reason for the appearance of "spider" is the use of a weak solution for brickwork. And, perhaps, it just worn out and requires a planned restoration.
Your actions: completely remove the cracked solution, and then thoroughly moisten the seams of the masonry. Seal the slits with a freshly prepared mixture. It is possible and at all to insure against occurrence of this defect by means of facing of the case of the furnace by heat-resistant ceramic tile.
Through gaps in the furnace casing.
Three reasons can cause such a defect. The first is a violation of the rules for dressing the joints of bricks, the second is the contact between the red-hot metal parts of the firebox and the masonry, the third is the pressure of the external structures on the furnace body.
Your actions: if you find a defective site of masonry, disassemble it and fold again according to all the rules of the cut. In the case where the metal part of the firebox acts as the culprit for the destruction, completely free it from contact with the bricks( thermal gaps of at least 1 cm).The third reason will require the detachment of the furnace from the heavy objects resting on it. Only after this it will be possible to restore the integrity of the masonry.
