Novovyatskiy Ski Plant from Kirov region (Russia) is going to reduce about 35 thousand tons of СО2 per annum

INFOBIO: Such project was applied to the second tender of Kyoto JI projects in the Russian Sberbank. Aim of the project is utilization of bark and wood waste (BWW) by way of their combustion in the boilers for generating heat energy with the simultaneous natural gas consumption reduction.

Project concept
The project is implemented at the Novovyatskiy Ski Plant (“NSP”). The project includes construction of four boilers of KE type, running on the bio-fuel - bark and wood waste.
Throughout many years the issue of BWW utilization at the plant was resolved using DKVR boilers, designed for burning of solid fuel, including BWW.
Prior to the project realization, technical condition of the DKVR boilers did not allow utilization of the entire BWW volume and by the year of 2006 made impossible their further operations, therefore a part of the BWW was accumulated at the stockpile. After the decision to shutdown inefficient DKVR boilers it became necessary to resolve the issue of BWW utilization in some way.
As main boilers for steam generation at the NSP two natural gas fired GM boilers has been used since 1980.
The project includes the construction and operation of two KE 10/24 СО boilers and two КЕ 10/14 PM boilers of total heat capacity 28 MW(th), with mechanical fuel supply and ash removal systems that will allow for providing the plant production facilities and third-party consumers with heat energy. Implementation of up-to-date technologies ensures the reduction of electricity use by new boilers as compared to the old DKVR boilers.
This project resolves the issue of the use of biomass wastes of various composition and wood wastes of various humidity (sawdust, splints, veneers, lump wastes and bark) as fuel for electricity generation and for depletion of heavy ash fractions by way of using the KE boilers.
As applied to the project, the BWW are:
- wood bark;
- sawdust;
- chips and chip dust;
- lump wood wastes.
The major part of BWW is formed during the preparation of the wood raw material before processing (barking) and during the wood sawing.
The project includes the realization of the following technical solutions:
1. Successive de-commissioning of the old DKVR boilers.
2. Successive commissioning of the new BWW fired KE boilers.
3. Implementation of the automation system for the boilers’ automated running.

Expected project results
Utilization of the accumulated BWW both at the “NSP” and the neighboring companies;
The steam generation by the new KE boilers will replace the equivalent amount of steam, generated due to natural gas firing at the existing GM boilers;
Decrease of the BWW transportation to the dump up to the complete elimination;
Reduction of СО2 emissions due to natural gas burning by 31.5 thousand tons per annum;
Reduction of methane emissions due to anaerobic biomass decomposition at the landfill approximately by 3.96 thousand tons of СО2-eq per annum (average for the period of 2008-2012);
Reduction of expenses for natural gas purchases and decrease in environmental pollution payments;
Additional financial receipts from emission reduction units (ERU) sales due to greenhouse gases (GHG) emission reductions.
