1. A removable thermal insulation comprising:
heat-insulating blocks, wherein:
the heat-insulating blocks are made of a steel cladding sheet and filled with heat- insulating material,
the heat-insulating blocks are interconnected by longitudinal side walls,
the steel cladding sheet comprises a strong reinforced lattice;
the heat-insulating blocks being fastened together using locks positioned at intersections of each face of the heat-insulating blocks, wherein:
the locks consist of grips and hooks,
the grips are made in the form of rounded flexible and elastic gripping plates, whereby the grips are compressible,
each hook is made in the form of stamped walls fixed to the block frame by means of stiffening ribs and a stainless plate,
hook walls form sections with a plane mutually contacting when mating with the surface of the resilient gripping plates, and
each gripper is interconnected by an annular spring fastened to the elastic gripping plates and connecting them symmetrically with respect to an axis of symmetry grippers with the formation of a compensated flexible tension.
