The first turbine is a gas turbine that is driven by burning, for example, natural gas. The second turbine is a steam turbine that is driven by the steam that is heated by the residual heat from the exhaust gases of the gas turbine (see the figure). Both turbines drive a generator where the electricity is produced. The electrical yield of this system is considerably higher (approx. 60 %) than when only one turbine is driven.<\/p>\n<h3>Receive this Technical Bulletin<\/h3><div class=\"frm_forms  with_frm_style frm_style_formidable-style-2\" id=\"frm_form_10_container\" >\n<form enctype=\"multipart\/form-data\" method=\"post\" class=\"frm-show-form  frm_js_validate  frm_ajax_submit  frm_pro_form \" id=\"form_gated-content-technicalbulletin\" >\n<div class=\"frm_form_fields \">\n<fieldset>\n<legend class=\"frm_screen_reader\">Gated content - Technical Bulletin<\/legend>\r\n\r\n<div class=\"frm_fields_container\">\n<input type=\"hidden\" name=\"frm_action\" value=\"create\" \/>\n<input type=\"hidden\" name=\"form_id\" value=\"10\" \/>\n<input type=\"hidden\" name=\"frm_hide_fields_10\" id=\"frm_hide_fields_10\" value=\"\" \/>\n<input type=\"hidden\" name=\"form_key\" value=\"gated-content-technicalbulletin\" \/>\n<input type=\"hidden\" name=\"item_meta[0]\" value=\"\" \/>\n<input type=\"hidden\" id=\"frm_submit_entry_10\" name=\"frm_submit_entry_10\" value=\"687c4d81bb\" \/><input type=\"hidden\" name=\"_wp_http_referer\" value=\"\/en-uk\/wp-json\/wp\/v2\/technical-bulletin\/3187\" \/><div id=\"frm_field_108_container\" class=\"frm_form_field form-field  frm_required_field frm_top_container\">\r\n    <label for=\"field_ovtcv\" id=\"field_ovtcv_label\" class=\"frm_primary_label\">Company name\r\n        <span class=\"frm_required\">*<\/span>\r\n    <\/label>\r\n    <input  type=\"text\" id=\"field_ovtcv\" name=\"item_meta[108]\" value=\"\"  placeholder=\"Enter your company name\" data-reqmsg=\"Dit veld mag niet leeg zijn.\" aria-required=\"true\" data-invmsg=\"Text is invalid\" aria-invalid=\"false\"   \/>\r\n    \r\n    \r\n<\/div>\n<div id=\"frm_field_95_container\" class=\"frm_form_field form-field  frm_required_field frm_top_container\">\r\n    <label for=\"field_i0ku7\" id=\"field_i0ku7_label\" class=\"frm_primary_label\">Name\r\n        <span class=\"frm_required\">*<\/span>\r\n    <\/label>\r\n    <input  type=\"text\" id=\"field_i0ku7\" name=\"item_meta[95]\" value=\"\"  placeholder=\"Enter your name\" data-reqmsg=\"Dit veld mag niet leeg zijn.\" aria-required=\"true\" data-invmsg=\"Tekst is ongeldig\" aria-invalid=\"false\"   \/>\r\n    \r\n    \r\n<\/div>\n<div id=\"frm_field_96_container\" class=\"frm_form_field form-field  frm_required_field frm_top_container\">\r\n    <label for=\"field_5dtwb\" id=\"field_5dtwb_label\" class=\"frm_primary_label\">Email address\r\n        <span class=\"frm_required\">*<\/span>\r\n    <\/label>\r\n    <input  type=\"text\" id=\"field_5dtwb\" name=\"item_meta[96]\" value=\"\"  placeholder=\"Enter your email address\" data-reqmsg=\"Dit veld mag niet leeg zijn.\" aria-required=\"true\" data-invmsg=\"Tekst is ongeldig\" aria-invalid=\"false\"   aria-describedby=\"frm_desc_field_5dtwb\" \/>\r\n    <div class=\"frm_description\" id=\"frm_desc_field_5dtwb\">We will send the Technical Bulletin to this email address.<\/div>\r\n    \r\n<\/div>\n<div id=\"frm_field_97_container\" class=\"frm_form_field form-field  frm_top_container\">\r\n    <label for=\"field_cilho\" id=\"field_cilho_label\" class=\"frm_primary_label\">Phone\r\n        <span class=\"frm_required\"><\/span>\r\n    <\/label>\r\n    <input type=\"tel\" id=\"field_cilho\" name=\"item_meta[97]\" value=\"\"  placeholder=\"Optionally, enter your telephone number\" data-invmsg=\"Phone is ongeldig\" aria-invalid=\"false\" pattern=\"((\\+\\d{1,3}(-|.| )?\\(?\\d\\)?(-| |.)?\\d{1,5})|(\\(?\\d{2,6}\\)?))(-|.| )?(\\d{3,4})(-|.| )?(\\d{4})(( x| ext)\\d{1,5}){0,1}$\"  \/>\r\n    \r\n    \r\n<\/div>\n\t\t<input  type=\"hidden\" name=\"item_meta[98]\" id=\"field_technical_bulletin_post_id\" value=\"3187\"  data-frmval=\"3187\"   \/>\n\t\t\t\t<input  type=\"hidden\" name=\"item_meta[100]\" id=\"field_2y8p3\" value=\"Pre-commission cleaning of 5 Heat Recovery Steam Generators\"  data-frmval=\"Pre-commission cleaning of 5 Heat Recovery Steam Generators\"   \/>\n\t\t<div id=\"frm_field_99_container\" class=\"frm_form_field form-field  frm_none_container\">\r\n    <label for=\"g-recaptcha-response\" id=\"field_vn6xk_label\" class=\"frm_primary_label\">reCAPTCHA\r\n        <span class=\"frm_required\"><\/span>\r\n    <\/label>\r\n    <div  id=\"field_vn6xk\" class=\"frm-g-recaptcha\" data-sitekey=\"6LcepM4qAAAAAMz7wDwxASFEeQVkg_Hdo6gakGc2\" data-size=\"normal\" data-theme=\"light\"><\/div>\r\n    \r\n    \r\n<\/div>\n<div id=\"frm_field_111_container\" class=\"frm_form_field  frm_html_container form-field\"><small>We treat your data confidentially.
