Feature : Distri ct energy New 70 MW waste to energy power plant commissioned Bioenergy International Internat ional No 81, 5-2015 17 Italian boilers heating up Russian northwest Heat and power from low or even zero cost wood waste fuels is something that Italian biomass boiler manufacturer Uniconfort is finding a growing interest for in northwestern Russia. a district heating system is currently being assembled near the city of Oktyabrskiy and will soon supply biomass heat to homes, shopping centres, schools, kindergartens and other buildings. The project is being achieved in cooperation with District Heating Ustiyanskiy (UTK) and includes the installation of five GLOBAL 800 boiler models, each with thermal output of a power of 9 million kcal (≈ 37.7 GJ) per hour. The plant will use sawmill residues and bark supplied by Ustiyanskiy Wood Company (ULK), a sister company to UTK. The plant will be operational by the end of 2015. – We are also building a co-generation plant for Ustiyanskiy Wood Company (ULK) in the district of Arkangelskiy. This plant will use wood residues and bark from the sawmill to provide heating for the wood kilns and pellet dryer and electricity for the complex. It is scheduled to be operational by the end of 2016, affirmed Davis Zinetti Davis, CEO, for Uniconfort. These are not the first biomass heat projects in northwestern Russia for the Italian boiler manufacturers, the company has already completed a district heating plant in the town of Severoonezhsk for the Russian oil and gas major Gazprom. – We were contacted by Gazprom that has operations in the Siberian oil and gas fields, explained Zinetti. These fossil fuels are widely used throughout Russia in city district heating systems. However many places are not connected to an oil or gas pipeline network as it is often uneconomical to construct the network needed. – Not to mention problems that turn up when you find yourself having to cross the countryside in extreme weather conditions, he said. Severoonezhsk reaches 40 degrees Celcuis below zero, and is not served by a pipeline. Moreover it is cut off from the road and rail freight network for several months of the year. All the buildings are connected to a district heating network, which used a very old and highly polluting boiler. – At the same time the city is surrounded by thousands of miles of forests and the wood processing industry is thriving here. However many sawmills just dumped their wood waste only 10 km from the heat plant as there was no market for such residues. This we could use as boiler fuel, said Zinetti. In just 18 months, Uniconfort installed a plant consisting of four 6 MWth boilers and it was possible to use the distribution networks already present, by applying apparatus exchangers to adjust the pressure. As for maintenance, technicians were trained on site for ordinary maintenance programmes with a dedicated team of Italian experts to provide assistance in case of extraordinary measures. – The presence of the plant has triggered a series of synergies and partnerships for the supply of fuel and the management of the plant, leading to a gradual growth of prosperity in the town. This has increased the overall demand for electric power, which is maxing out the power line that feeds the site. – Constructing a new connection was too expensive and difficult to implement in the short term considering the climate, which is why we have designed a new biomass cogeneration plant that will render the facility completely self-sufficient by the end of 2015, ended Davis Zinetti. Although there are no committed incentives in Russia, Gazprom and other parties, including regional government agencies, are observing this type of investment with keen interest. Especially in regions with harsh climatic conditions and an abundant availability of forest biomass.

Built next to the Ferrybridge ‘C’ Power Station near Knottingley in West Yorkshire the 70 MWe plant uses waste-derived fuels from various sources of municipal solid waste, commercial and industrial waste. The GBP 300 million plant has been under construction for over three years by Swiss engineering, procurement and construction (EPC) contractor Hitachi Zosen Inova (HZI). MEL and the FM1 plant is a 50:50 joint venture project between SSE plc, one of the UK’s largest energy utilities and US-based Wheelabrator Technologies Inc., a world leading energy from waste (EfW) company operating in North America, Europe and China. BI81/4964/AS DP Cleatech and China Everbright sign fourth biomass power plant deal China-based biomass combustion technology specialist DP CleanTech and China Everbright International, a major business conglomerate have announced the development of a new 30 MWe straw-fired biomass power plant in Nanqiao City, Anhui, China. This marks the fourth project for DP and Everbright International in 2015 and the sixth project between the two companies. DP’s advanced technology boiler will be optimized to handle locally abundant agricultural residues, thereby ensuring high availability throughout the year and a consistent source of additional income for local farming communities. – We work closely with Everbright and other key customers to ensure that the ongoing development of core technologies is matched ever more closely with individual customer requirements. Our knowledge and capabilities are enhanced through close collaboration with forward thinking clients such as Everbright Inter- national, commented Simon Parker, CEO, DP CleanTech. There are currently four DP and Everbright International biomass power plants in Anhui, and the Nanqiao plant will be the second such plant in the city. The plant will utilize DP’s patented high pressure, high temperature (HPHT) technology to reach annual availabilities of up to 7800 hours per year. DP has supplied over 50 projects in China, and over 80 projects around the world. – DP CleanTech is a world leading renewable energy solutions provider. By cooperating with DP CleanTech, we are going to achieve a winwin situation. Systematically utilizing agricultural straws will greatly improve China’s rural eco-environment and efficiency of agricultural productivity, Mr. Chen Xiao Ping, CEO, Everbright International in a statement.
