Claims

[Scope of utility model registration request]

The water chamber is divided into two upper and lower chambers by a partition plate, and the lower chamber is equipped with a nozzle for introducing water, and the upper chamber is equipped with a nozzle for discharging water. , a large number of through holes are provided in the tube plate of the water chamber, and heating tubes are inserted into the through holes in the upper and lower portions of the water chamber.
A body is inserted and fixed so as to communicate between the chambers, and one end of which is closed with an end plate is fixed to the tube plate, and the other end is fixed so as to surround the heating tube. A steam inlet nozzle and a drain outlet nozzle are provided, and the portion near the water chamber in the body is approximately vertically connected by a pair of partition plates whose tips are fixed to the tube plate and side ends are fixed to the inner wall of the body. The inner cylinder surrounding the heating tube is fixed to each of these partition plates with a slight gap between them and the inner wall of the body, and is also supported by a support plate. In a feed water heater that is equipped with a buttful for reducing superheated steam and a buttful for drain cooling on the lower partition plate and inner cylinder, there is a gap between the side edge of each partition plate welded to the inner wall of the shell and the inner wall of the shell. A water heater with a triangular reinforcing member formed at the connection part with the side end.
