The 40t/h medium-temperature and medium-pressure biomass boiler transformed passed the acceptance!

The 40t/h medium-temperature and medium-pressure biomass boiler transformed by Guangzhou Kechao Company for a sugar group company passed the acceptance!

The outstanding advantages of the reciprocating grate furnace are: the fuel ignition is basically double-sided ignition, which has a wider adaptability to the fuel; the fuel layer is constantly raked and loosened, the contact between the air and the fuel is greatly strengthened, and the combustion efficiency is high; the heat loss of mechanical incomplete combustion can be reduced through reasonable air distribution settings, and the nitrogen oxide emission can be reduced, and the environmental protection effect is good.

In 2023, Guangzhou Kechao Thermal Energy Co., Ltd. will renovate a 40t/h medium-temperature and medium-pressure pulverized coal boiler for a large sugar group, which was originally manufactured by Dongfang Industrial Boiler Company.

Boiler model: XG40-3.82/450-T

Design pressure: 3.83MPa

Superheated steam temperature: 450°C

Combined heat and power: supporting 3000Kw back-pressure steam turbine, all the exhaust steam is used in the sugar refining section

After the boiler is renovated, eucalyptus root crushed material is used as the main fuel, and a small amount of branch material and construction waste is mixed with water, about 40~45%, and the sediment content is about 10%, and the calorific value of the fuel sampled in front of the furnace is 2000Kcal/kg~2300Kcal/Kg. After the operation test of the whole crushing season in 2024, it is proved that the modified boiler is well adapted to the change of fuel, and the operating parameters fully meet the design requirements.
