In this design, the flue gases are routed through the furnace and the smoke pipe three times, and this superpass construction helps the boiler achieve even more reliable operation. The efficiency of the boiler is enhanced by the large combustion space and the internal combustion system. The exhaust smoke is minimized, and steady operation for a long time is achieved.<\/p>\n                    <\/div>\n                <\/div>\n            <\/div>\n\n            <div class=\"cwns-item\">\n                <button class=\"cwns-trigger\" aria-expanded=\"false\">\n                    <h3 class=\"cwns-question-text\">What is the purpose of the safety protection devices installed in the boiler?<\/h3>\n                    <div class=\"cwns-icon\"><\/div>\n                <\/button>\n                <div class=\"cwns-answer\">\n                    <div class=\"cwns-answer-content\">\n                        <p>The safety protection devices installed in the CWNS series boilers are designed to guarantee the safety of the boilers and to help prevent issues of overtemperature and overpressure. In the series of protection safety devices, there are pressure valves, interlock protection valves, and the addition of a cut off valves for low water. All of these devices, in conjunction, help to ensure safe water operation, and if water reaches dangerously low levels, combustion is stopped, and so is the feed system. These systems help to ensure personnel safety, as well as the safety of the equipment in the case of a malfunction.<\/p>\n                    <\/div>\n                <\/div>\n            <\/div>\n\n            <div class=\"cwns-item\">\n                <button class=\"cwns-trigger\" aria-expanded=\"false\">\n                    <h3 class=\"cwns-question-text\">What is the impact of the large-diameter corrugated furnace and furnace liner on the furnace heat transfer efficiency?<\/h3>\n                    <div class=\"cwns-icon\"><\/div>\n                <\/button>\n                <div class=\"cwns-answer\">\n                    <div class=\"cwns-answer-content\">\n                        <p>In the design of CWNS oil gas-fired hot water boilers, large diameter corrugated furnaces help increase the turbulent flow and the surface area available for heat absorption.
