The planless grate differs from the known similar gratings in that, in order to use existing designs of heating boilers, as well as upron design and metal consumption, it is made in the form of Z-shaped flat grate with an additional comb and to ensure air access to the fuel layer.

In order to reduce the loss of toiliv with a dip through the grate, as well as to use the existing constructions of otonitelnyh boilers, a joint was used, made up of a series of pig-iron unflanted one-grate grates, which are made in the form of Z-shaped tiles / with a comb 2 in the shelf plane to ensure air access to the fuel layer.

The grate is assembled in such a way that the upper tides of one grate are located above the pizhpe {1 shelf of the other grate. The supply of blast air to the small arms is measured along the Z-shaped channels 4, formed by 1 m adjacently located spike; campaign

After assembling the ticker, a grate is placed in the grate, which is then leveled along the grid and located on the shelf 5, forming an angle of repose 6, without waking up at the ashpit and providing air for combustion fuel. Such an arrangement of 2-shaped grates will practically eliminate the failure of the fuel through the grate and significantly increase the efficiency of the furnace.
