The invention discloses an energy-saving and environment-friendly anti-burst limestone kiln. The limestone kiln comprises a kiln body and a combustion chamber,wherein the combustion chamber is arranged in the kiln body,an automatic feeding inlet is formed in one side on the top of the combustion chamber,a fume exhaust pipe is connected with the other side on the top of the combustion chamber,and an automatic ash discharging outlet is formed in the bottom of the combustion chamber. A cavity is formed between the outer side of the combustion chamber and the inner side of the kiln body,a plurality of supporting devices are arranged in the cavity,each supporting device comprises a second supporting plate and a transverse plate,the sides,away from the second supporting plates,of the transverseplates are fixed to the outer wall of the combustion chamber,and the two ends in the middles of the other sides of the transverse plates are provided with second support rods respectively. The sides,away from the transverse plates,of the second support rods are provided with connection rods respectively,the sides,away from the second support rods,of the connection rods are provided with supportingcolumns respectively. The energy-saving and environment-friendly anti-burst limestone kiln has the advantages that the capacity of bearing the pressure between the kiln body and the combustion chamber is improved,and the leak-out and air-leakage phenomena are prevented.
