All design projects of power-generating equipment are developed by our design engineers.

Throughout the years boiler-making school (oriented at drum steam boilers) created on the basis of Barnaul Boiler Plant has been widely recognized. 

Sibenergomash designs and manufactures power equipment for new applications, and retrofits existing sites as well. Main directions of undertaken retrofits are as follows: conversion to another fuel, efficiency improvement, abatement of emissions, capacity increase.

*Steam superheater modification incorporates:

·   Integration of additional radiant stages aimed to smooth temperature, i.e. to reduce overburning of convective stage tubes and improve boiler cyclic load capability;

·   Measures to reduce pressure and temperature differentials in tubes (to reduce hazard of premature failure of heating surface headers);

·   Improvement of systems maintaining required distance between headers of convective stages to eliminate thermal and aerodynamic distortions in flue gas cycle.

·   Replacement of superheater surfaces made of 121812 steel with surfaces made of 59 steel.
