Department of Thermal Power Plants of MPEI proposed the concept of a boiler of 1000 MW for steam generation advanced ultra-supercritical parameters M-shaped profile. In this boiler it is proposed to make an invert boiler furnace. Output main and secondary steam header are proposed to be placed under inclined boiler passes as close as possible to the cylinders of the steam turbine. The feasibility of using advanced ultra-supercritical parameters is associated with the possibility of increasing the efficiency of the power unit by 4.2%. The paper describes the location of the designed s heat exchangers, the movement of water and steam, flue gases along the path of the boiler. Also given are the results of calculations of the proposed layout of the boiler, as the temperature of the working medium and flue gases at the inlet and outlet to the surface, the flue gas temperature at the inlet and outlet to the surface, the numerical values of the heat loss of the boiler, affecting the efficiency of the boiler. The calculated boiler efficiency is 93.07%. The description of the proposed fuel combustion scheme, which is a system of vertical-horizontal tangential torches, is also given.
