Brick Chimneys June 3, 2019 June 15, 2019 Laurie

However, brick chimneys are disadvantages. They are heavy, cumbersome, and require cleaning, because the rough inner surface of the accumulated soot, to the same brick under the influence of condensate and other adverse factors over time breaks down. Three-layer ceramic chimneys, fire clay refractories have a circular cross section, are more compact than brick, but they have more weight than steel chimneys and time-consuming to assemble. Glass and plastic chimneys designed to lower the temperature of combustion and we have not yet taken root. The most in demand today modular chimney heat resistant acid-resistant steel. Such systems are smoke removal long term and easy to maintain and repair, are not afraid of moisture and corrosion, aggressive external environment, extreme temperatures.

They are relatively inexpensive, quickly assembled from a well-fitting items lighter brick chimneys and do not require a special foundation. Steel chimneys are perfectly combined with a variety of types of stoves, fireplaces, household boilers and furnaces. Can be installed inside the old brick chimneys. Steel chimney is not difficult at any time be dismantled or replaced. Stainless steel chimneys are installed on diesel generators, industrial boilers, working on different kinds of fuel, gas-and turbine units. Modular steel chimneys are divided into two types: single-circuit (single-) and double-walled tubes.

The first type – a stainless steel tube without the outer shell and insulation, its thickness – up to one millimeter in depending on the destination chimney. Usually laid inside the brick chimney systems for improved traction and easier cleaning. Single-flue fireplace is applicable only in heated spaces to connect fireplace to an existing brick chimney. Double-walled chimney is used for both domestic use and in industry. Usually consists of two layers (walls) of stainless steel and insulation between them. Such a system provides rapid heating chimney and good traction, does not allow condensation and prevents the outer wall of the pipe from overheating, and the building – from the fire. This insulated chimney is called is called chimney sandwich. Most of these pipes are used outside of a building or inside the wooden buildings. Chimneys sandwich proved themselves well in unheated areas and outside buildings, baths and saunas. Chimney sandwich – the most demanded today chimney fire. To protect the flues flues from the combustion products of modern boilers, columns and other devices running on gas, increase traction and reduce the formation of condensate, the gas ducts. Flue has a large cross-sectional dimension that can effectively remove large amounts of flue gas in low pressure and temperature. Manufacturers offer flues of different types: horizontal and vertical, and rotary-pass, lift and lower. Flues are made of sheet steel or thermoplastics. Flue to the output of hot gases must be equipped with reliable insulation.
