Removable filter sieve for combustion piping

摘要

A combustion piping system for a metal melting furnace is disclosed in which a sieve is used upstream of a flashback arrester to collect particulate matter carried in the fuel flow to the furnace so as to minimize maintenance of the flashback arrester. The sieve is mounted in a sieve holder that is arranged to be rapidly removed from and replaced in the piping system during furnace operation so as to minimize the pressure drop in the fuel flow to the furnace.
