Some aspects of use of organic containing waste for electrical and thermal energy generation

Abstract

<jats:p>This article is devoted to the problem of energy generation from the non-processed part of waste, both industrial and municipal. Some aspects of use of gasification products of organic-containing wastes and landfill gas are considered. The presented comparison shows that landfill and generator gases can be attributed to the group of medium-calorific gases used both as boiler fuel and for production of liquid synthetic fuels. It should also be noted that generator and landfill gases contain a significant proportion of inert gases (from 22% to 60%), which is significantly higher than that of natural gases. Inert gases in landfill and generator gases are different. In the first case it is CO<jats:sub>2</jats:sub>, in the second it is N<jats:sub>2</jats:sub>. Unlike solid fuel boilers, in a boiler designed to burn gaseous fuels (natural gas), synthetic gases can also be burned without significant additional reconstruction. Due to the difference in gas calorific value, the ratio of fuel to air (with a constant coefficient of excess air α) will change to obtain the necessary thermal power, however, the volume of flue gases will differ slightly. Therefore, the flow sections of the boiler furnace can be saved.</jats:p>

Use of Heat Pumps in the Hydrogen Production Cycle at Thermal Power Plants

“…In the Russian Federation, in order to reduce the harmful impact of the produc and energy sectors on the environment, the Federal Law "About Limiting Greenh Gas Emissions" was issued [9]. Such a policy of Russia stimulates research in the fiel using secondary energy resources [10][11][12][13][14], in particular, heat pump units (HPU) [12-By 2020, fossil resources accounted for 96% of the main sources of hydrogen, of w steam reforming of natural gas is about 48% [15]. With the implementation of Net Zero E sions Scenario-the pathway for the global energy sector to achieve net zero CO2 emiss by 2050 [16]-by the International Energy Agency, as hydrogen production increases share of hydrogen produced by electrolysis will increase significantly (Figure 1).…”
