Che cosa sono gli NOx?<\/h2>\n

[\/et_pb_text][et_pb_text admin_label=”Paragraph” _builder_version=”4.27.4″ text_font=”Montserrat||||||||” text_font_size=”16px” text_line_height=”2.2em” header_font=”||||||||” custom_margin=”|||” global_colors_info=”{}”]NOx refers to a collective term for pollutants composed of nitrogen oxides, primarily including nitric oxide (NO) and nitrogen dioxide (NO\u2082).
\nIn industrial combustion systems, NOx is typically formed at a ratio of 90\u201395% NO and 5\u201310% NO\u2082. The formation mechanisms of NOx are classified into three types: \u2460 Thermal NOx, generated by oxidation of atmospheric N\u2082 via the Zeldovich mechanism at temperatures exceeding 1,300\u00b0C; \u2461 Fuel NOx, formed from the oxidation of nitrogen-containing fuels; \u2462 Prompt NOx, produced in high-temperature zones with hydrocarbon radicals. NOx is a gaseous pollutant strictly regulated under the Dutch NEer and EU IED directives, with typical emission limits ranging between 30\u2013150 mg\/Nm\u00b3.[\/et_pb_text][\/et_pb_column_inner][\/et_pb_row_inner][\/et_pb_column][\/et_pb_section][et_pb_section fb_built=”1″ admin_label=”CTA Section” _builder_version=”4.16″ use_background_color_gradient=”on” background_color_gradient_direction=”90deg” background_color_gradient_stops=”rgba(242,246,249,0) 75%|#f2f6f9 75%” background_color_gradient_start=”rgba(242,246,249,0)” background_color_gradient_start_position=”75%” background_color_gradient_end=”#f2f6f9″ background_color_gradient_end_position=”75%” custom_padding=”120px|0px|120px|0px” animation_style=”slide” animation_direction=”right” animation_intensity_slide=”1%” saved_tabs=”all” global_colors_info=”{}”][et_pb_row column_structure=”1_2,1_2″ use_custom_gutter=”on” custom_padding_last_edited=”off|desktop” admin_label=”CTA Row” _builder_version=”4.16″ background_color_gradient_direction=”90deg” width=”100%” max_width=”100%” module_alignment=”center” custom_padding=”|||” custom_padding_tablet=”120px|||” custom_padding_phone=”120px|0px|0px|0px” use_custom_width=”on” width_unit=”off” custom_width_percent=”100%” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.16″ custom_padding=”80px|||12%” custom_padding_tablet=”|10%||10%” custom_padding_phone=”|10%||10%” custom_padding_last_edited=”on|tablet” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_text _builder_version=”4.27.4″ text_font=”||||||||” header_font=”||||||||” header_2_font=”Montserrat||||||||” header_2_font_size=”40px” header_2_line_height=”1.5em” max_width=”800px” custom_margin=”||20px|” custom_padding=”|||” custom_padding_tablet=”0px|10%||70px” custom_padding_phone=”0px|10%||50px” custom_padding_last_edited=”off|desktop” header_2_font_size_tablet=”35px” header_2_font_size_phone=”35px” header_2_font_size_last_edited=”on|phone” header_2_line_height_tablet=”1em” header_2_line_height_phone=”1.4em” header_2_line_height_last_edited=”off|desktop” global_colors_info=”{}”]<\/p>\n

I pericoli degli NOx<\/h2>\n

[\/et_pb_text][et_pb_text _builder_version=”4.27.4″ text_font=”Montserrat||||||||” text_font_size=”16px” text_line_height=”2.2em” header_font=”||||||||” header_2_font=”Montserrat||||||||” header_2_text_color=”#21323d” header_2_font_size=”40px” max_width=”800px” custom_margin=”|||” custom_padding=”|||” custom_padding_tablet=”|100px||70px” custom_padding_phone=”|||50px” custom_padding_last_edited=”off|desktop” text_line_height_last_edited=”off|desktop” global_colors_info=”{}”]<\/p>\n

Dal punto di vista ambientale, gli NOx sono precursori dell'ozono (O\u2083) e del particolato fine (PM2.5), contribuendo all'inquinamento atmosferico urbano e all'aumento dello smog. Combinandosi con il vapore acqueo, gli NOx possono anche generare piogge acide, acidificando il suolo, la vegetazione e le fonti idriche, con conseguente impatto sugli ecosistemi. Inoltre, gli NOx aggravano l'effetto serra e accelerano il cambiamento climatico. Per quanto riguarda la salute umana, gli NOx irritano l'apparato respiratorio, aumentando il rischio di asma, bronchite cronica e altre malattie; l'esposizione a lungo termine pu\u00f2 portare a una riduzione della funzionalit\u00e0 polmonare e al cancro.<\/p>\n
