Abstract

Inventia se refera la termotehnica si poate fi utilizata in sistemele de incalzire cu apa, precum si pentru incalzirea apei menajere. Cazanul de incalzit apa contine un corp cu manta de apa, dotat cuun racord pentru gaze de ardere, o camera de ardere dotata cu arzator, racorduri de debitare si evacuare a apei, elemente cave orizontale cu suprafete de incalzire prin convectie, care sunt cuplate cu mantaua de apa si formeaza un canal de gaze in forma de labirint, si un incalzitor de apa menajera. Cazanul suplimentar contine o portiune descendenta a canalului de gaze, unde in partea inferioara este amplasat racordul pentru gaze de ardere, schimbatoare de caldura cu tevi, cuplate cu mantaua deapa si amplasate pe toata lungimea canalului de gaze si in camera de ardere, guri pentru evacuarea funinginii, care sunt cuplate cu canalul de gaze, si un sistem automatizat de dirijare si control a regimului de lucru al cazanului, care include un bloc computerizat, conectat cu un bloc de control, la randul sau, conectat cu un bloc al arzatorului,un bloc de distribuire a apei fierbinti, un bloc de incalzire a apei menajere si un bloc de securitate. Toate blocurile sunt conectate intre ele si elementele de lucru ale cazanului, precum si la un bloc de alimentare, iar blocul computerizat este conectat la un bloc computerizat la distanta cu bloc de alimentare. Rezultatul inventiei consta in intensificarea transferului de caldura prin majorarea timpului de contact al gazelor de ardere cu suprafetele de incalzire prin convectie, in majorarea randamentului, in automatizarea dirijarii si controlului regimului de lucru al cazanului si in posibilitatea folosirii catorva surse de incalzire a apei menajere.The invention relates to thermotechnics and can be used in water heating systems, as well as for domestic water heating. The water heating boiler contains a body with a water jacket, equipped with a connection for combustion gases, a combustion chamber equipped with a burner, water discharge and discharge connections, horizontal cavity elements with convection heating surfaces, which are coupled with the water mantle and forms a maze-shaped gas channel, and a domestic water heater. The additional boiler contains a descending portion of the gas channel, where in the lower part is located the connection for combustion gases, heat exchangers with pipes, coupled with the lower mantle and located along the entire length of the gas channel and in the combustion chamber, mouths for evacuation. soils, which are coupled to the gas channel, and an automated system for directing and controlling the boiler operating mode, which includes a computerized block, connected with a control block, in turn, connected with a burner block, a hot water distribution block, a domestic water heating block and a security block. All the blocks are connected to each other and to the working elements of the boiler, as well as to a power supply block, and the computerized block is connected to a remote computerized block with power supply block. The result of the invention consists in the intensification of the heat transfer by increasing the contact time of the flue gases with the heating surfaces by convection, in increasing the efficiency, in the automation of the management and control of the boiler working regime and in the possibility of using several sources of domestic water heating.
