Abstract

The article considers the search for alternative fuel relevant for the present question. For example, the use of wood pellets or biomass. The use of biofuels can also put a stop to the biggest environmental problem - climate change on the planet. Biofuels have less effect on the greenhouse effect, because plants that then use as biofuels absorb carbon from the atmosphere and produce oxygen. The properties of Trapa natans spread and multiply rapidly, make it possible to consider it as an alternative fuel for boiler houses of the hot water supply system (HWS). Coal combustion is usually characterized by high combustion temperatures and contains more sulfur and nitrogen than wood and other biomass. This means that the burning of coal leads to the release of sulfur oxide and nitrogen oxides, as well as toxic pollutants that are bound by adsorption or absorption. Wood combustion smoke also contains gaseous air pollutants, which may have a number of adverse health effects. Among these gases are carbon monoxide, nitric oxide, acrolein, formaldehyde, benzene, and other organic compounds, including carboxylic acids, numerous saturated and unsaturated hydrocarbons, aromatic compounds, and oxygen organic compounds. Combustion of biomass, which, for example, as a result of salt water treatment or transport by sea, contains chlorine, can also lead to emissions of chloro-organic compounds. To establish a connection between the combustion heat and the calorific value of the substance, the equations of the chemical combustion reaction are analyzed. The calorific value of the fuel is calculated using the empirical formula proposed by D.I. Mendeleev. To do this, an analysis of the elementary composition of the fuel is performed, that is, the percentage of oxygen, hydrogen, carbon, sulfur, nitrogen, ash, water in it. The necessary amount of Trapa natans, firewood and coal required to heat 500 liters of water from 30 to 100 °C has been established. It has been proved that Trapa natans can be used as an alternative fuel for boiler systems of HWS for enterprises adjacent to reservoirs.
