Abstract

The invention discloses a condensing cast iron modular boiler, which includes a boiler body, a burner, a condenser and a controller, and is characterized in that: the boiler body includes a front furnace piece, a rear furnace piece, and There are multiple middle furnace pieces; the front furnace piece, the middle furnace piece and the rear furnace piece are equipped with a combustion chamber, a main flue, a side flue, etc. for supplying high-temperature flue gas flow; at the same time, the furnace piece is also equipped with a cooling water supply flow water channel; the surface of the furnace is also provided with a heat conduction cone to increase the heat conduction area. The furnace slices are connected through the fixed part, and the connection between the furnace slices is through the cast iron ring joint, which realizes no leakage and seals under the state of thermal expansion and contraction, forming a closed container; Matching, the flue gas flow path is in an "S" shape, which prolongs the residence time of the flue gas in the furnace, thereby increasing the heat exchange process. The invention has the characteristics of reasonable structure, light weight, large output, reasonable overall structure, small volume and beautiful appearance.

Description

technical field [0001] The invention relates to the field of gas boilers, in particular to a condensing cast iron modular boiler. Background technique [0002] Traditional cast iron boilers have factors such as short combustion process, high exhaust gas temperature, water vapor waste, and large air excess coefficient in flue gas, which lead to problems such as low boiler thermal efficiency, waste of fuel, and excessive emissions. The main reason is that reducing the exhaust gas temperature will produce condensed water. Since the condensed water is weakly acidic, it is easy to corrode the boiler body. Therefore, boiler manufacturers often increase the exhaust gas temperature to evaporate the condensed water. The problem of high exhaust gas temperature can be solved by improving the form of the boiler. Under the premise of controlling smog, saving energy and reducing consumption, it is urgent to design a new type of gas-fired boiler to solve the above disadvantages, so that t...
