33、4 Requirements for the liner 4.1 General 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 th

34、e brickwork is classified in accordance with EN 13084-4: 2005, 4.2.3 (see also Table 1). Table 1: Liner brickwork classes Mortar types MT1 MT2 MT3 Resistance to chemical attack BT1 A (A)1) very high BT2 B high BT3 C medium BT4 D low Brick types BT5 E no chemical attack Resistance to chemicalattackve

36、shall be verified according to EN 13084-4 taking into account characteristic values of compressive and flexural strength for the different brickwork classes which are specified in EN 13084-4: 2005, Table 3 or are determined by tests in accordance with EN 1052-1 and EN 1052-2 respectively.

38、gth 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

39、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 m

40、ay 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 pressu

41、re 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 i

42、n 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,

43、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 us

44、ed 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.

45、2.3 and Table 1 of this standard dependent on the degree of chemical attack (see also EN 13084-1: 2000, Table 3). EN 13084-5:2005 (E) 7 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 reinfo

46、rcement. 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

47、 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

48、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 t

49、o 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
