Abstract:
The invention relates to a sectional boiler made from cast iron or aluminum, and particularly, a condensing boiler, having substantially annular sections, a front section (1), at least one rear section (2) and at least one central section (3) being provided, said annular sections forming a combustion chamber (4) with a substantially circumjacent heat exchanger configured from a sectional block having interconnected annular water chambers (5, 5', 5") connected to each other and gap-like heating gas flues (6) that extend approximately radially between two neighboring sections (1, 2, 3) of mutually adapted geometry, and that discharge into an exhaust collecting chamber (9). The sectional boiler further comprises a return port (7) and a feed port (8). The invention aims to optimize a sectional boiler made from cast iron or aluminum as a condensing boiler in particular in terms of compactness and robustness. The invention is characterized in that: the return port (7) and feed port (8) are disposed on opposite sides of the sectional block; the fluid passes through the water chambers (5, 5', 5") of the sections in sequence, starting from the return port (7); and, the individual sections (1, 2, 3) are each hydraulically provided with overflow openings (14) at only one point of the circumference, the individual sections being connected by the overflow openings (14) to a neighboring section (1, 2, 3) on at least one side.
Abstract:
A heat exchanger (1) has an exchanger unit (20), comprising at least one first coiled conduit and one second coiled conduit (21, 23) that are substantially coaxial, and a casing (2) for housing the exchanger unit (20). The casing (2) has a first end wall (3), a second end wall (4), and a peripheral part (5) between the two end walls (3, 4). Each conduit (21 -23) has an inlet and an outlet, where the outlet of the first conduit (21, 23) is connected substantially in series to the inlet of the second conduit (22). The exchanger unit (20) is supported by the first end wall (3) of the casing (2), with the inlet of the first conduit (21) and the outlet of the second conduit (22) which are substantially at the first end wall (3) of the casing (2)·

본 발명은 원형으로 감겨진 인접하는 파이프가 서로 밀착되도록 코일을 가공하여 감겨진 코일에 의해 형성되는 원통형의 내부공간을 따라 연소생성물이 흐르도록 유로를 형성함과 아울러 코일 내부를 따라 흐르는 난방수와의 전열효율을 극대화함으로써 열교환기 구조의 간소화 및 소형화와 더불어 열교환기 내부의 청소작업 또한 용이하게 수행할 수 있도록 하는 열교환기에 관한 것이다. 이를 실현하기 위한 본 발명의 열교환기는, 파이프를 원형으로 감아서 만든 코일 형상의 열교환기에 있어서, 인접하는 파이프를 밀착시킴으로써, 상기 인접하는 파이프 사이로 연소생성물의 흐름이 차단되고, 상기 감겨진 파이프의 코일에 의해 형성되는 원통형의 내부공간으로만 연소생성물이 흐르도록 이루어진 것을 특징으로 한다.
Abstract:
A heat exchanger (1) with improved thermal efficiency comprising a container body (2) crossed by a forced flow of hot fluid (7) and at least one coiled duct (3) crossed internally by at least one fluid to be heated (6), the coiled duct (3) being accommodated inside the container body (2) and being struck by the hot fluid (7) in order to heat the fluid to be heated (6), the heat exchanger comprising a plurality of fins (30) which are formed on the outer surface of the coiled duct (3) and which run substantially along the entire longitudinal length of the coiled duct (3) in order to guide the hot fluid (7) along the coiled duct (3) so as to increase the heat exchange between the hot fluid (7) and the fluid to be heated (6).

Abstract:
A tank-tankless water heater includes primary and secondary heat exchangers, and a combustor for the production of flue gases. In operation, water is first heated as the water and flue gases flow through primary heat exchanger. The water flows into the tank where it is stored and again heated as the flue gases flow through the secondary heat exchanger. A pump moves the water from the secondary heat exchanger, through the primary heat exchanger, and back to the secondary heat exchanger for storage as needed to maintain the stored water at a desired temperature Water is drawn from the secondary heat exchanger during initial demand to provide a ready source of hot water, and the hot water supply is maintained by the primary heat exchanger during sustained hot water draws. The primary heat exchanger may include a temperature or temperature differential control system.
