Boiler drum longitudinally arranged chain grate hot water boiler

Abstract

The invention discloses a boiler drum longitudinally arranged chain grate hot water boiler, and relates to a hot water boiler to solve the problems that the conventional boiler has low thermal efficiency and high coal consumption, pipes are easy to block, and smoke discharging temperature is high. The boiler drum longitudinally arranged chain grate hot water boiler comprises a left longitudinal upper header, a right longitudinal upper header, a left longitudinal water tank, two first vertical water distributing pipes, two second vertical water distributing pipes, a plurality of upper transverse headers, a plurality of lower transverse headers, a front transverse header, a rear transverse header, a plurality of first water cooling wall pipes, a plurality of second water cooling wall pipes,a plurality of groups of third water cooling wall pipes, a plurality of groups of fourth water cooling wall pipes, a plurality of groups of fifth water cooling wall pipes, a plurality of groups of sixth water cooling wall pipes, a plurality of groups of upper convection banks, a plurality of groups of front convection banks, a plurality of groups of rear convection banks, and at least one convection economizer, wherein the front transverse header and the rear transverse header are communicated with a left coking prevention ark and a right coking prevention ark; adjacent upper boiler drums in a plurality of upper boiler drums, and the left longitudinal upper header and the right longitudinal upper header and the respectively adjacent upper boiler drums are communicated thorough the plurality of upper transverse headers. The boiler drum longitudinally arranged chain grate hot water boiler is used for central heating.

Description

technical field

[0001] The invention relates to a hot water boiler. Background technique

[0002] Most of the boilers currently produced are water-fire tube boilers with small heating area, low thermal efficiency, large coal consumption and high operating costs. The threaded smoke pipe is often blocked, and the smoke pipe needs to be cleaned every half a month. The labor intensity is high, and the furnace needs to be shut down for maintenance. Contents of the invention

[0003] The purpose of the present invention is to solve the problems of low thermal efficiency, large coal consumption, easy blockage of pipes and high exhaust gas temperature of existing boilers, and further provide a vertically mounted boiler drum chain grate hot water boiler.

[0004] The technical solution adopted by the present invention to solve the above-mentioned problems is: the drum vertical chain grate hot water boiler of the present invention includes a furnace body, a layered coal feeder, a c...
