Abstract
The utility model discloses a coal-saving device for a boiler. The coal-saving device for the boiler comprises a water jacket and an economizer, the water jacket is wrapped on an outer side of a discharge flue of the boiler and is positioned between the economizer and the boiler, a water inlet of the water jacket is connected with a softened water tank, and a water outlet of the water jacket is connected with a water inlet of the boiler. The discharge flue of the boiler penetrates through the economizer and then is connected with a chimney. The top of the economizer is connected with the softened water tank, and the bottom of the economizer is connected with the water inlet of the boiler. By the aid of the coal-saving device for the boiler, smoke-exhausting temperature can be kept round 200 DEG C, water inlet temperature is increased by about 50 DEG C, and accordingly service life of impellers is effectively prolonged, and coal consumption quantity is reduced.
Description
Technical field
The utility model relates to a kind of boiler, and specifically a kind of boiler is used the coal saving device.
Background technology
Boiler is a kind of energy conversion, and to fuel such as boiler input coals, and through the boiler conversion, outwards output has hot water or the steam of certain heat energy.The hot water that produces in the boiler or steam can be directly for industrial production and people's lives provide required heat energy, also can be converted to mechanical energy by Steam Power Equipment, or by generator mechanical energy is converted to electric energy again.The flue gas of at present boiler generation directly is discharged in the air.Because exhaust gas temperature has caused the waste of energy on the one hand up to 300 ℃ in the boiler running process, also easily cause on the other hand the boiler machine impeller that facings the wind often to burn out.
Summary of the invention
The problem that exists in order to overcome prior art, the purpose of this utility model provides a kind of boiler and uses the coal saving device, adopts the exhaust gas temperature of this device boiler can remain on about 200 ℃, and inflow temperature improves about 50 ℃, not only effectively prolong the service life of impeller, and saved coal consumption.
The purpose of this utility model is achieved through the following technical solutions:
A kind of boiler is used the coal saving device, it is characterized in that: this device comprises water jacket and economizer, described water jacket is coated on the outside in boiler exhaust gas road and between economizer and boiler, the water inlet of water jacket is connected with softened water tank, and the delivery port of water jacket is connected with the water inlet of boiler; The boiler exhaust gas road is connected with chimney after passing economizer; The top of economizer is connected with softened water tank, and the bottom of economizer is connected with the water inlet of boiler.
In the utility model, described economizer comprises the cavity that is made of housing, and the boiler exhaust gas road is entered by the cavity lower end and drawn by the cavity upper end; Be provided with the crooked water pipe that arranges of one group of S type in the cavity, the import of water pipe is connected with softened water tank, and the outlet of water pipe is connected with the water inlet of boiler.Between economizer and chimney, be provided with air-introduced machine.
The utility model is provided with water pump at the softened water tank water outlet, and softened water tank is connected with water jacket with economizer by water pump.
After using the utility model, the exhaust gas temperature of boiler can remain on about 200 ℃, and inflow temperature improves about 50 ℃, has not only effectively prolonged the service life of impeller, and has saved coal consumption.The utility model is applicable in the various boilers.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of boiler described in the utility model is used the coal saving device, see Fig. 1, this device comprises water jacket 1 and economizer 2, water jacket 1 is coated on the outside in boiler exhaust gas road 3 and between economizer 2 and boiler 6, the water inlet 11 of water jacket 1 is connected with softened water tank 4, and the delivery port 12 of water jacket is connected with the water inlet 61 of boiler.Boiler exhaust gas road 3 is connected with chimney after passing economizer 2.Economizer 2 comprises the cavity that is made of housing 21, and boiler exhaust gas road 3 is entered by the cavity lower end and drawn by the cavity upper end; Be provided with one group of S-type crooked water pipe 22 that arranges in the cavity, the import of water pipe 22 is connected with softened water tank 4, and the outlet of water pipe is connected with the water inlet of boiler 61.Be provided with water pump 41 at softened water tank 4 water outlets, softened water tank 4 is connected with water jacket by water pump 41 and economizer 2 and is connected.Between economizer 2 and chimney, be provided with air-introduced machine 5.The top of economizer 2 is connected with softened water tank 4, and the bottom of economizer 2 is connected with the water inlet of boiler 61.
After using the utility model, the exhaust gas temperature of boiler can remain on about 200 ℃, and inflow temperature improves about 50 ℃, has not only effectively prolonged the service life of impeller, and has saved coal consumption, can be sparing in the use of coal about 100kg in per 8 hours.
