To affect the normal use of boiler, so that often replacement, causes big inconvenience and trouble to the use of boiler.Separately
Outside, burner hearth is near grate and the high temperature heat radiation of grate lower part clinker, furnace body can only slattern in vain because that can not absorb,
Boiler coal consumption and operating cost are virtually also increased in this way.Entitled " a kind of water-cooled grate for Verital coal-fired boiler "
Application No. is the Chinese utility model patents of " CN200920082133.2 " to disclose a kind of water cooling for Verital coal-fired boiler
Fire grate, it includes several water-cooled grate tubes, it is characterized in that: several inclined water-cooled grate tube tools are at regular intervals to form one side by side
A water-cooled grate is welded in burner hearth, and the water inlet end of water-cooled grate tube is connect with boiler header, and the water outlet of water cooling tube is fixed on
On boiler water wall, semilune baffle is equipped at burner hearth the right and left Non-water-cooled furnace grate tube, and semilune baffle upper has tool
The refractory concrete of certain slope.However, the product water cooling tube heat transfer effect is poor, the thermal efficiency is lower, improves production cost,
Reduce economic benefit.
Utility model content
To solve the above-mentioned problems, the utility model devises a kind of environmental protection, energy saving pot using the corrugated fire grate of water cooling
Furnace, effects of energy conservation and environmental protection is good, and the thermal efficiency is high, and structure is simple, easy to use, extends service life.
The technical solution of the utility model are as follows:
A kind of energy-saving environmental protection boiler using the corrugated fire grate of water cooling, including boiler body, the boiler body are equipped with combustion
Chamber is burnt, fire grate is equipped in the combustion chamber, the fire grate is corrugated structure, bottom can be made to enter gas, fills burning more
Point, improve efficiency of combustion；The fire grate is hollow structure, and inside is filled with recirculated water, and is equipped with circulation water inlet and circulation
Water out carries out heat exchange with combustion chamber bottom pyrocarbon and clinker, to reach energy-efficient purpose, while avoiding fire grate temperature mistake
Height ensure that the service life of fire grate；Homogeneous vertical offers up-small and down-big truncated cone-shaped through-hole on the fire grate, is convenient for clinker
Pass through, avoids blocking.
Further, the circulation water inlet and the circulating water outlet are connected with boiler water wall, in favor of furnace
Body-internal-circulation water circulates.
Further, the fire grate goes out horizontal by 3 °~5 ° angles convenient for the hook of cinder.
Further, the combustion chamber is externally connected to burner, and burner is a large amount of to combustion chamber release after start-up
Flame；The burner be neat gas burner, the external natural gas tube of neat gas burner, and be equipped with control valve control gas
Flow.
Further, the one end of the fire grate stretches out outside the combustion chamber, and extension end is equipped with vibrator or ultrasonic wave
Oscillator can make fire grate generate vibration, and then come into full contact with coal and air on fire grate, keep burning more abundant, and
Make the water and extraneous sufficiently heat exchange in fire grate, meanwhile, the ashes after burning are fallen to from fire grate.The vibration of the vibrator
Frequency is adjustable, can be adjusted according to the needs.
Further, it is equipped with high temperature resistant damping bed course between the fire grate and the boiler body, avoids vibration to boiler
Ontology has an impact.
Further, the combustion chamber is equipped with oxygen injecting port, and the oxygen injecting port is set around the periphery of the combustion chamber
Have multiple, improves efficiency of combustion.
Utility model has the advantages that effects of energy conservation and environmental protection is good, the thermal efficiency is high, and structure is simple, easy to use, extends
Service life.
The utility model is described in further detail with reference to the accompanying drawings and examples.
