MD3819C2 - Heating boiler (variants) - Google Patents

Abstract

The invention relates to the heat engineering and can be used in the water heating systems and for heating of household water.The heating boiler (variant I) contains a body with water jacket, a combustion chamber equipped with burner, water inlet and outlet branches, hollow horizontal elements with convective heating surfaces, communicating with the water jacket and forming a gas duct in the form of labyrinth, where in the lower part it is placed a branch for combustion materials, equipped with a valve, a vertical hollow partition with convective heating surfaces, communicating with the water jacket, a hollow element, equipped with an inclined convective heating surface and communicating with the water jacket, tubular heat exchangers, coupled with the water jacket and placed along the full length of the gas duct and into the combustion chamber, soot removal hatches and a safety valve, coupled with the gas duct, and a household water heater. The boiler additionally comprises an automated boiler operation regime management and control system, including a computerized unit, coupled with a control unit, connected in its turn to a block of the burner, a water distribution block, a household water heating block and a safety block. The block of the burner is connected to the valve with remote control and to the elements providing the draft in the gas duct, with which the branch for combustion materials is equipped, all blocks are connected between them and to the operating elements of the boiler, as well as to the power unit, and the computerized unit is connected to a computerized remote unit through the power unit.Into the heating boiler (variant II), the combustion chamber is equipped with a guide reflector, coupled with the water jacket, and is placed in the upper part of the gas duct.The heating boiler (variant III) contains two combustion chambers, one being placed in the upper part of the gas duct, the other - in its lower part, and two branches for combustion materials, one placed in the upper part of the gas channel, the other - in the lower part of the lower combustion chamber.The result consists in intensifying the heat transfer by increasing the time of contact of the combustion materials with increased temperature with the convective heating surfaces and the temperature difference of the heat-transfer agents, in the automation of the working and control regime of the boiler, in simplifying the construction, in reducing the specific quantity of metal of the boiler, in using different kinds of combustible without changing the burners and more energy sources for household water heating.
