Regarding heat exchanger materials and types
Thread Content
Could some expert please translate these English abbreviations: LA (in terms of materials); for heat exchangers: Shell & Tube -NES, Shell & Tube -BEM, Shell & Tube -BEU; Fire-tube Boiler
Shell means a casing, and tube means a pipe. What is written there refers to the structural types of heat exchangers; one can refer to the specifications in GB151, where “boiler” denotes a heating boiler. But I wasn’t able to translate that whole part; looking forward to an answer below. Last edited by wode*aohei on 2009-2-17 12:42.]
Regarding heat exchangers: Shell & Tube - NES, Shell & Tube - BEM, Shell & Tube - BEU; I believe these are the types of shells used in shell-and-tube heat exchangers.
1. LA should be an abbreviation for “lacuna”, meaning this vacancy； 2. NES, BES, and BEU are all basic types of shell-and-tube heat exchangers ； 3. Fire-tube Boiler refers to a fire-tube boiler.
NES BES BEU is a TEMA standard; the first character represents the head type, the middle character denotes the shell type, and the last character indicates the rear head type
Could you introduce fire-tube boilers so that everyone can learn about them?
