FIRING APPARATUS WITH FIRE GRATES COOLED BY LIQUID Russian patent published in 2002 - IPC

FIELD: firing apparatuses with liquid cooled fire grates. SUBSTANCE: in firing apparatus each of liquid cooled fire grates has supply and return lines for cooling agent. Supply and return lines are connected with condensation device opened to atmosphere. U-shaped receiver for cooling liquid is mounted in supply line. One branch of said receiver has liquid height providing arbitrarily selected maximum pressure in system. Another short branch is connected with central distributor for separate fire grates. Distance between the most low point of flow of cooling liquid in the most low fire grate and upper point of short branch corresponds to selected safety size along height providing pressure suppressing propagation of vapor bubbles formed in fire grates in order to prevent reversing of cooling liquid flow. EFFECT: improved design, enhanced safety. 13 cl, 1 dwg
