The liner is formed by brickwork using clay/ceramic bricks according to 5.1 and mortar according to 5.2. It shall be
designed in accordance with EN 13084-4 and shall be erected according to the state of the art. Dependent on the
brick and mortar types used the brickwork is classified in accordance with EN 13084-4: 2005, 4.2.3 (see also Table
1).

values of compressive and flexural strength for the different brickwork classes which are specified in EN 13084-4:

4.2.3 Compressive strength
In order to meet this requirement the bricks shall comply with the respective values given in Table 2 and the mortar
with the values given in Table 4.
4.2.4 Flexural tensile strength
In order to meet this requirement the bricks shall comply with the respective values given in Table 2 and the mortar
with the values for initial shear strength in accordance with Table 4.
4.2.5 Resistance to fire
Soot fire resistance shall only be verified for brick liners conveying flue gas of solid combustibles and whose inner
diameter in the case of circular section or smallest inner lateral length in the case of rectangular section is less than
1,0 m.
In this case EN 1443: 2003, 6.3.2 applies.
For liners different from the above mentioned ones the verification of soot fire resistance may be omitted. This also
applies to liners for chimneys with an upstream flue gas treatment.
Limit values of permissible temperatures for bricks and mortars shall be declared by the manufacturer.
4.2.6 Gas tightness
En 13084-1: 2000, 4.2.4 specifies that in a brickwork liner positive internal pressure shall only be allowed in a short-
term or exceptional situation. It is not allowed during normal operation conditions. The state of the art has shown,
that gas tightness may not be required.
4.2.7 Flow resistance
A mean roughness value for brickwork liners to carry out flow calculations is given in EN 13084-1: 2000, Table A.3.
4.2.8 Dimensioning/ Thermal resistance
Heat flow calculations shall be carried out according to EN 13084-1: 2000, 4.2.3. Thermal resistance shall be
calculated according to EN 13084-1: 2000, A.2.2 using the values of thermal conductivity specified in EN 13084-1:
2000, Table 1.
4.2.9 Thermal shock resistance

This requirement is met by testing successfully the bricks and mortar for resistance to temperature change
according to Table 2 and Table 4 respectively.

4.2.10 Resistance to freeze-thaw

Resistance to freeze-thaw shall only be required for bricks and mortar used in parts of the liner near the mouth of
the chimney. The requirement is met by testing successfully the bricks according to 6.1.9. For mortar see 6.2.8.

4.2.11 Durability
Durability to chemical attack is verified by classifying brickwork (bricks and mortar) in accordance with EN 13084-4:
2005, 4.2.3 and Table 1 of this standard dependent on the degree of chemical attack (see also EN 13084-1: 2000,
Table 3).

5 Materials
5.1 Bricks
5.1.1 General
Bricks may be of plain rectangular shape or they may be profiled to develop shear keys in the mortar, or to accept
metal reinforcement.
The requirements for bricks are given in Table 2 and Table 3.
The surface of bricks should be free of cracks.
Smaller cracks (microcracks) shall not exceed the following values:
 Crack width ≤ 0,05 mm;
 Crack length ≤ 10 mm;
 Crack depth ≤ 2 mm.
5.1.2 Bricks Type BT1
Bricks type BT1 are suitable for brickwork resistant to "very high chemical attack" due to acids and alkalis.
Attention shall be paid to their sensitivity to thermal shocks.
5.1.3 Bricks Type BT2 (a) and BT2 (b)
Bricks type BT2 (a) and BT2 (b) are suitable for brickwork resistant to "high chemical attack" in the presence of
acids or alkalis.
The chemical resistance of bricks type BT2 (a) derives from the properties of their ingredients, whereas type BT2
(b) derives their chemical resistance mainly from their high density and low permeability.
When there is a risk of thermal shock, only bricks type BT2 (a) shall be used due to their resistance to spalling.
5.1.4 Bricks Type BT3
Bricks type BT3 are suitable for brickwork resistant to "medium chemical attack". They comprise dense bricks of
burnt clay or shale.
5.1.5 Bricks Type BT4
Bricks type BT4 are used in brickwork subjected to high temperatures. They are suitable for brickwork at operating
conditions not more severe than "low chemical attack". They comprise refractory bricks of fireclay.
5.1.6 Bricks Type BT5
Bricks type BT5 are characterized by a low thermal conductivity. They are suitable for brickwork not subjected to
chemical attack. They comprise bricks of diatomaceous clay (such as Moler).

5.2 Mortars
5.2.1 General
The following mortars need to be used:
a) Type MT1: Resin mortars;
b) Type MT2: Potassium silicate mortars;
c) Type MT3: Mortars based upon hydraulic cement.
Raw materials shall have characteristics permitting the finished product to conform to the requirements of
this standard.
The requirements for mortars are given in Table 4.
5.2.2 Type MT1 Resin mortars
Type MT1 resin mortars (normally formed by epoxy, phenolic or furan resins mixed with siliceous or
carbon powder) are suitable for brickwork resistant to "very high chemical attack" in contact with flue gas
condensates both alkaline and acid. Phenolic and furan resins based mortars, when mixed with carbon
powder, are also resistant to HF action.
Heat resistance is limited to 80 °C (epoxy) and 180 °C (phenolic) whereas furan based mortars can
withstand temperatures under operating conditions up to 250 °C.
5.2.3 Type MT2 Potassium silicate mortars
Type MT2 potassium silicate mortars are suitable for brickwork resistant to "high chemical attack" and, if
only due to acids, to "very high chemical attack". These mortars comprise a mixture of a chemically inert
powdered filler, containing a setting agent and a liquid potassium silicate binder. Halogen-free potassium
silicate mortars shall be used and silicon fluoride hardeners shall not be allowed. Once hardened and
dried, these widely used mortars exhibit excellent resistance to most acids (except HF) and solvents.
They are also resistant to intermittent exposure to mild alkalis after acid treatment. Their prime function,
however, is in resisting the strong acids commonly found in fossil fuel flue gas environments.
Heat resistance is limited to 1000 °C.
5.2.4 Type MT3 Mortars based upon hydraulic cement
Type MT3 mortars based upon hydraulic cement are suitable for brickwork resistant to "low chemical
attack". The following types (listed in order of their increasing acid attack resistance) of cement may be
used for these mortars:
a) Portland cement (CEM I according to EN 197-1);
b) Blast furnace cement (CEM III according to EN 197-1) and sulphate resistant cement;
c) Calcium-aluminate cement.
The aggregate shall comprise sand of mineral origin or finely ground burned clay. Lime must not be
added.
Heat resistance is limited to
d)  T = 200 °C for mortar based upon Portland cement
e)  T = 600 °C for mortar based upon blast furnace cement and sulphate resistant cement
f)  T = 1000 °C for mortar based upon calcium-aluminate cement.
