BOILER heating water CAST IRON GAS

摘要

Cast iron hot water boiler heating gas for heating individual dwellings (houses) equipped with water heating system with a working fluid pressure to 0.3 MPa (3 kgf / cm ²⁾ and temperatures up to 95 degrees ° C, with forced or gravity (natural) circulation coolant at low pressure natural gas combustion in automatic mode on the coolant temperature.; The technical result of the claimed utility model is:; -increasing the heating efficiency of the boiler water heating steel in comparison with gas boiler taken as the prototype hot-water heating boiler with hot water extraction;; - energy saving and resource saving (the gas flow rate decreases to 30%);; - improving the accuracy of regulation predetermined heating parameters that provide the required comfort in the room;; - small size and low weight allow for installation of the boiler heating boiler water heating iron gas without increasing the floor structure.; The technical result in the claimed utility model is achieved by the fact that, compared to a useful model adopted as prototype, the boiler heating water with selection of hot water, comprising a body with a base, a compound pipe with a chimney, introduced into the internal volume of the boiler heat exchanger adheres to the combustion chamber and forming with cavity closed loop water jacket of coolant medium collector main burners with pilot burner, a viewing window for monitoring the operation of pilot and main burners and ignition zap Flax burners, nozzles for connection to the heating system in the claimed utility model boiler heating hot water cast iron gas is formed as a block of the assembly of rectangular shape sealed decorative tonkolistovyh panels with insulation, comprising a top panel, a front panel, a removable front panel and the instrument panel, wherein said heat exchanger is made of cast-iron sections with side edges and needle heat exchanger surfaces, forming convective flues for passage glowing GOVERNMENTAL flue gases, wherein the iron section of the heat exchanger are interconnected by sealed conical nipples and fixed pins ties, wherein said combustion chamber is laterally limited water cooled sections of the heat exchanger and the front and rear fireproof thermal insulation, wherein said pilot burner is mounted on said front panel, and said main burner manifold with nozzles mounted on said removable front panel, which also holds said observation window for observation Ia the operation pilot and main burners and ignition pilot burner, and on top of said heat exchanger is installed dymosborny collector configured as a welded box structure to said pipe for connection to the flue, the boiler is provided with safety automatics with gas burner device comprising a traction sensor mounted the front of the front surface of said collector dymosbornogo configured to disable the boiler in the absence of the chimney draft, the flame sensor smonti Rowan on said front panel and adapted as a thermocouple, mounted on said dash panel temperature indicator and coolant pressure regulation and safety unit, hermetically screwed on the threaded end of said collector main burners gas burner device, wherein the housing of said safety and regulation unit mounted tasks handle coolant temperature, said regulating and safety unit comprises a safety valve, a control valve Art stabilizer of gas pressure, coolant temperature controller and an apparatus for controlling power of said pilot burner, said control unit and security associated with the sensor of traction sensor of the flame, with a temperature gauge and coolant pressure, and said safety valve control unit and security with its input connected to the network gassing, which is located in the gas valve supplying the gas to the gas burner with automatic safety device and output the control valve unit controls Nia safety connected to the collector of main burners gas burner device, wherein the safety equipment with gas burner device is arranged to automatically control the water outlet temperature from the boiler supply stop of gas at pilot burner flame extinction, the absence of thrust and lowered in the network is below the minimum pressure.
