Boiler K-7 typ Vesko B for wood chips combustion	Hot water boilers for NG combustion type Rapido

Summary: The project is to convert a hot water boiler from coal to biomass combustion. Boiler house of company Handlovská energetika s.r.o. with total installed heat input 127,12 MW is located in area of mine facility -Handlovské bane. The generated heat is supplied to this facility as for district heat demand of other residential users.

The installed boilers K-5 and K-6 are dedicated for coal combustion and auxiliary fuel - NG is used for combustion stabilization, but that are able to operate at 100% NG input too. andor NG combustion Boiler K-1 is furnished by pre= combustion fluidised bed reactor and is used for coal combustion only. The above configuration represents the baseline of projects. In new project for CO₂ abatement framework were in year 2006 installed boiler K-7 type Vesko B 3 MW for hot water generation with thermal input 3,49 MW, dedicated for wood chips combustion and 4 hot water boilers for NG combustion type RAPIDO Three of them have thermal input 0,600 MW and one of them 0,320 MW. This new configuration enable to decrease the share of cial input, that lead to CO₂ decrease.

Aims:

• increase the efficiency
• decrease the amounts of air pollution compounds such as SO₂, PM, NO_x and CO₂.
• decrease the fuel costs
• decrease of solid waste

Summary of Results: By using wood chips as fuel instead of coal, several positive results have been achieved. The amount of CO₂ and SO₂ emissions have decreased. It has also decreased the heat production costs.
