Which to choose brick kiln

Russian frosts suggest the presence in the house of a good heating. Perfect and historically the favorite option of heating the Russians is a furnace, most of all - it is Russian. That it was longer to heat from it was nice, you should know how to choose a brick oven. That's why we decided to dedicate today's article, how to choose a brick oven and a brick oven for the best to choose or not take at all.

Which to choose brick kiln: brick of what material is best

Those who at least somehow faced with bricks, we already know that, based on the production of the material, these products may be:

silicate;
ceramic.

For the manufacture of ceramic bricks used clay mixtures which are processed by calcining. Silicate bricks prepared from the known-sand mixtures containing certain additives and subjected to autoclave treatment. The color of the products may vary due to the presence in them of necessary pigments.

In preparation for the construction of the furnace and having to choose between a silicate or ceramic articles, to reflect on the problem of how to choose a brick oven, not even worth: Stove accept only ceramics. The characteristics of this product

we wrote. That's about it, then we will talk further.

According to their purpose, ceramic brick is divided into:

corpulent ordinary used Pechnikov masonry elements inside the furnaces;
also called ordinary finishing. His first name is quite eloquent. Calling the finishing brick - is the external finish of already built structures. With more homogeneous structure such brick outwardly more accurate.

Range of ceramic bricks

When deciding which brick kiln is better to choose, you should know that pottery used Pechnikov, presented in three different varieties, designed for a specific part of the masonry oven:

Third grade. These bricks are dense enough, they perezhzheny moderate, weak frost differ. When a small porosity of these products have good thermal conductivity. They are great for the furnace base.

Second grade. These little unburned and non-frost resistant bricks are porous enough. In comparison with the first grade, their heat capacity smaller. Sound, resulting in their prostukivanii somewhat deaf.
First grade. The structure of these bricks has good density and annealed. They possess a flat surface and a saturated color.

Which to choose brick furnace, its specific spreading element

IN masonry chimney bricks of different varieties used for arranging various design elements:

foundation;
a combustion chamber;
chimney;
a chimney;
facing.

When deciding which brick oven is better to choose for laying the foundation, it should be understood that the furnace element is exposed, coming out of the ground - moisture and cold. Moreover, the entire mass of the future construction falls on him. Third grade is attractive in terms of price. First grade is ideal if you plan to build a heavy oven a great height. If you stay in a very cold areas should consider using clinker has a significantly high strength and resistance to frost.

A characteristic feature of the furnace is the presence of very high temperatures. Sometimes it is built of first-class ceramic bricks, but it is refractory, the furnace is still insufficient. Therefore often spread from a furnace brick or refractory silica.

When using silica bricks some caution should be exercised. It can not be laid in the body and in the base of the furnace, where lime is very likely presence: such products are destroyed when entering into reaction with alkaline materials. Fireclay brick is not so fussy. Its styling is possible with arrangement of any element of the furnace.

brick parameters important for furnaces

Fire resistance, first comes to mind when talking about the furnace, it is not the only parameter that must be considered in the course of work. So, have a great importance in these works:

frost;
strength;
the thermal conductivity, thermal storage capacity;
mass of brick and its size.

Be aware that the strength of bricks is an indicator of their brand. Sense labeling is as follows: if we take e.g., M150 stamp, this means that this brick can withstand a load up to 150 kg / cm2.

For furnaces only brick to be used, without any voids. It is also important that all the bricks are the same model. This will facilitate their conjugation in the course of laying. The only exceptions are the bricks for the arrangement of the combustion chamber.

Which brick is not suitable for oven

So, we told you what to brick oven is better to choose. Now, however, we point out those of its varieties, which can not be used. It:

slip-casting a brick;
silicate;
raw;
hollow.

The last of these may simply raskisnut when laying. In the sand-lime brick unattractive its low heat resistance. The first of these species is able to crumble under the influence of constant thermal fluctuations.
