Description

A kind of straw burning boiler smoke drop ash denitrogenates cooling all-in-one machine
Technical field
The utility model is related to a kind of straw burning boiler smoke drop ash and denitrogenates cooling all-in-one machine.Straw burning boiler is denitrogenated Cooling all-in-one machine is the high density granular that a kind of use straw and weeds biolobic material are pressed into or is rolled into less than certain Size particle is the thermal energy exchange equipment of fuel, belongs to biomass combustion boiler.
Background technology
Existing straw burning boiler only has boiler body, and inside turns to heavy grey room without flue gas, is not the combustion of boiler overhead Expect feeding structure, low temperature nitrogen removing device and heat energy exchange device are then arranged in outside boiler body, burner and body of heater flange And bolt connection.Said structure, many unfavorable factors can be produced for boiler furnace.
1. during straw burning boiler combustion stalk fuel, certain density flying dust can be formed, the more other fuel of these flying dusts Flying dust amount it is big, this is just easier to form attachment on convection heating surface and accumulated, and influences heat exchange and the flue gas of heating surface Flow velocity, the heat exchange property of boiler is poor, and abrasion of the flying dust to straw boiler pipeline is larger, add the maintenance of boiler tubing into This.
All it is to apply flange and bolt connection, burner integrated suspension is in boiler sheet 2. conventional burner is connected with body Body chassis bottom, whole weight is all attached on boiler pan, is posed a big pressure to boiler pan structure load-bearing.
4. the conveying of fuel is usually to enter burner in burner bottom pushing tow fuel, or enters combustion from side feed fuel Burner, so all can produce fuel and block and dispense inequality.
3. low temperature nitrogen removing device and heat energy exchange device(Economizer)It is arranged in outside boiler body, is connected by flue, I.e. floor space is larger and wastes the material of connection flue, also add installation cost.
