Water in 143 gap is heated, in the present embodiment, clear by arranging the first deashing chamber 141 and second on heat exchanger tube 143
Grey room 142, for clearing up the flue dust that flue gas deposits in heat exchanger tube 143, it is to avoid flue dust blocks heat exchanger tube 143, leads to heat exchanger tube
The ground that exhaust gas volumn minimizing in 143, the first deashing chamber 141 and the second deashing chamber 142 are turned during being respectively arranged at flow of flue gas
Side, can collect flue dust effectively, thus ensure that the flue gas circulation in heat exchanger tube 143, improve the heat exchange effect of heat exchanger tube 143
Rate.After fuel combustion, can be discharged by discharging opening 112, the fuel uncombusted part of discharge can continue combustion on conveyer belt 152
Burn, conveyer belt 152 is located at and reclaims in combustor 151, and the heat that unburnt fuel combustion produces can be by reclaiming combustor 151
Pass to Heat Room 140, Heat Room 140 can heat the water in Heat Room 140 using this portion of energy, reclaims combustor 151
Setting, is conducive to realizing reclaiming completely by the heat of fuel, capacity usage ratio is higher, and heat transfer effect is more preferable.Meanwhile, the second air compartment
155 setting, makes fuel also form fluid bed on conveyer belt 152, unburnt fuel abundant after-flame on conveyer belt 152,
It is effectively improved the utilization rate of fuel.
In sum, the biomass boiler 100 that the present embodiment provides, by arranging the first deashing chamber on heat exchanger tube 143
141 and second deashing chamber 142, many heat exchanger tubes 143 are connected with the second deashing chamber 142 by the first deashing chamber 141, flue gas exists
In heat exchanger tube 143 during flowing, turn in the first deashing chamber 141 and the second deashing chamber 142, easily deposit dust, the first deashing
Room 141 and the design of the second deashing chamber 142, are avoided that flue dust deposits in heat exchanger tube 143, and are mainly deposited on the first deashing chamber
141 and second in deashing chamber 142, and the cleaning to the first deashing chamber 141 and the second deashing chamber 142 is convenient, it is to avoid flue dust blocks up
Plug heat exchanger tube 143, thus ensure that the circulation of flue gas in heat exchanger tube 143, being conducive to improving heat exchange efficiency, improving the profit of fuel
With rate.
