Emission of Air Pollutants in the Hot Water Production

Abstract

Optimisation of the parameters of a pump chamber for solid-state lasers with diode pumping by the optical boiler method V V Kiyko, V I Kislov, E N Ofitserov et al. Abstract. The result of the deteriorating condition of the environment and climate change is to increase the efficient use of fuel and energy and the rational use of energy resources. Great potential for reducing consumption of fossil fuels are stuck in heating systems ranging from generation, transmission and distribution and ending with the recipients rationalize their consumption of heat. Efficient production of heat is obtained during optimal boiler load. The boiler type WR operates with the highest efficiency of 80-85%, the rate of fuel consumption is the lowest, and the process is close to complete combustion. In such conditions to the atmosphere are emitted mainly: SO 2 , CO 2 and NO X . Pollutants such as CO, CH 4 , HF, HCl, NH 3 , etc., are the result of incomplete and imperfect combustion, that is, when the boiler is working inefficiently [1][2][3]. Measurements of pollutant concentrations were performed using an analyzer FTIR Gasmet DX4000. Fourier Transform Infrared Spectroscopy is a technique of measuring that allows a very precise identification of qualitative and quantitative range of compounds, including gaseous pollutants. Device used to measure the concentrations of gaseous pollutants allow determining the amount of carbon, sulphur and nitrogen compounds, which measurement is not defined any rules, including chlorine compounds, hydrogen, methane, ammonia and volatile organic compounds. In this publication presents part of the literature the use of heat for domestic hot water production in summer and heating demand in winter. Described the characteristics of the water boilers WR type used for heating. Presents the results study of the emissions in the production of hot water for the summer and winter seasons.

Assessment of Reducing Pollutant Emissions in Selected Heating and Ventilation Systems in Single-Family Houses

“…In Poland, the existing research is also dispersed, and most studies compare the emissions from modern heating systems that rely on renewable energy sources with conventional systems that are fired by fossil fuels. However, the number of the analyzed variants and/or pollutants are relatively small, which narrows down the scope of these analyses [30,[32][33][34]. Some studies focus on a single energy source or a single pollutant [35,36].…”

Influence of Emissions from the Stationary Heat Sources upon the Atmospheric Precipitation Pollution with Inorganic Nitrogen in the Sevastopol Region

“…The authors of [4] calculated that the volumes of emissions of nitrogen oxides during the hot water production significantly vary in the warm and cold periods. Thus, in summer, the emissions are 539 mg/s and in the heating season -3,175 mg/s.…”

“…Consequently, the city's boiler-houses changing over to gaseous fuels should have a positive effect on atmospheric air quality, since there are no emissions of sulfurous substances and mercury when burning natural gas. Nitrogen oxides per unit of energy are also released several times less than when using oil, petrol or coal 4 .…”
