Перевод малой теплоэлектроцентрали на сжигание местного топлива в объемах, обеспечивающих ее работу в летнее время

The paper gives characteristics of local fuel. It presents the results of the technical and economic assessment of the project of transfer of one boiler unit of the small CHPP from natural gas to local solid fuel, which is proposed to be burned in the furnace with "fluidized bed". It shows that the simple payback time of such a reconstruction of the boiler with a capacity of 50 t/h of steam with the parameters of 3.4 MPa, 440 °C for the main groups of local fuel will pay off in less than two years. In order to increase economic indicators of the CHPP with steam turbines working with poor vacuum during summer time it is proposed to install an additional circuit based a small turbine with a low-boiling working fluid.
