Abstract

The invention discloses a utility boiler economizer which comprises a feed water pipe (4), an inlet header (1), a heat transfer surface (2), an outlet header (3) and an outlet pipe (8). Fuel gas flows through the heat transfer surface to heat feed water. A first bypass pipe (5) is arranged between the feed water pipe (4) and the outlet pipe (8) for connect the pipes, and a bypass thermoregulator (9) is arranged on the first bypass pipe (5).
