The practical application of 75 t/h water cooled vibratory grate boiler with direct combustion of straw and stalks shows that the adaptability to fuel is wide

the capability of load variation is strong

the maximum load can reach to 80 t/h

the steam temperature is stable

having good regulation behavior

all parameters have reached or surpass the designed values.During period of operation

the exhausted gas temperature from boiler is about 135 ℃

phenomena of low-temperature corrosion and ash clogging have never been discovered.In the event of burning rice-husks in the boiler

the carbon content in fly ash is 9.6%

and in big slags is 12.2%

it is obtained after conversion that the boiler efficiency to be 89.36%

being greater than the designed value.
