Este modelo foi aprimorado do decorrer dos anos no qual foi reivindicado através do modelo de utilidade BRMU8203312-9U2 descrita abaixo na integra que trata de uma disposição introduzida em caldeira móvel a diesel idealizada em um recipiente metálico cilíndrico compartimentado e trocador de calor mobilizável, destinado a aquecer água e produzir vapor em áreas rurais, a ser utilizado para o aquecimento de ambiente e esterilização do solo, sendo para isso dotada de original disposição construtiva, com o objetivo de melhorar a sua utilização e desempenho em relação aos outros modelos usualmente encontrados no mercado, agregando a característica de mobilidade, visto ser constituída de um corpo cilíndrico (1) disposto horizontalmente sobre um chassi contendo corpos retangulares alongados (2) e corpos retangulares transversais (3), no qual ostenta em sua outra extremidade um engate (4) com trava, sendo que a base é apoiada sobre um eixo contendo pneumáticos (5) em seus respectivos extremos, e que o corpo cilíndrico (1) é constituído centralmente um dispositivo injetor-queimador (9) alimentado com óleo diesel dos reservatórios cilíndricos (10), que insere os bicos queimadores por dentro dos tubos cilíndricos, queimando o óleo diesel, fornecendo o calor por condução térmica induzida por chama direta e pela fumaça produzida. In the present art we can cite document BRPI7802819-1 of 5/7/1977 which describes a gas water heater in which it operates with an externally heated cylinder container so that cold water enters on the one hand and exits on the other. hot. This model has been refined over the years in which it was claimed through utility model BRMU8203312-9U2 described below in its entirety which deals with an arrangement introduced in a mobile diesel boiler idealized in a compartmentalized cylindrical metal container and movable heat exchanger, intended for to heat water and produce steam in rural areas, to be used for space heating and soil sterilization, having for this purpose an original constructive disposition, aiming to improve its utilization and performance in relation to the other models usually found in the market. , adding the mobility feature, since it consists of a cylindrical body (1) arranged horizontally on a chassis containing elongated rectangular bodies (2) and transverse rectangular bodies (3), in which at its other end a coupling (4) with the base is supported by an axle containing tires (5) in its and that the cylindrical body (1) is centrally constituted diesel-fueled burner nozzle (9) from the cylindrical reservoirs (10), which inserts the burner nozzles into the cylindrical pipes, burning the diesel oil, providing the heat by direct flame-induced thermal conduction and the smoke produced.

[004] Para melhorar os modelos acima descritos, o autor idealizou um sistema de aquecimento de água industrial potável descrito no documento BRPI1105376-3A2 projetado com uma bomba (1) de recalque instalado externamente à fonte de calor, a qual suga a água do interior do reservatório do aquecedor de água industrial (2) por meio de uma tubulação de aço inox (3) provida de uma pluralidade de furos e recalca para circulação na serpentina de troca térmica (4) em contato com o trocador de calor a gás (5) ou trocador de calor a vapor (6) sendo que ao finai essa água de recirculação aquecida é despejada no fundo do reservatório mantendo a temperatura desejada para cada processo mantendo-a estável.  [004] To improve the models described above, the author devised a potable industrial water heating system described in document BRPI1105376-3A2 designed with a booster pump (1) installed outside the heat source, which sucks water from inside. the industrial water heater reservoir (2) by means of a stainless steel tubing (3) provided with a plurality of holes and repressions for circulation in the heat exchange coil (4) in contact with the gas heat exchanger (5 ) or steam heat exchanger (6) whereby at the end this heated recirculating water is poured into the bottom of the reservoir keeping the desired temperature for each process keeping it stable.

[006] No modelo aqui proposto o aquecimento primário da água é realizado pelo trocador água/vapor e a manutenção desta temperatura é feita pelo trocador água/condensado.  [006] In the model proposed here the primary heating of water is performed by the water / steam exchanger and the maintenance of this temperature is done by the water / condensate exchanger.

[007] já o foco do presente requerimento consiste no reaproveitamento do calor que ocorre quando a água condensada nos equipamentos externos é reaproveitada através do seu bombeamento novamente para a caldeira para aproveitar o percentual de energia térmica que está presente nesta água condensada.  [007] Already the focus of the present requirement is the reuse of heat that occurs when condensed water in external equipment is reused by pumping it back to the boiler to take advantage of the percentage of thermal energy that is present in this condensed water.

Ou seja, o presente modelo traz como novidade inventiva um sistema que tem como novidade inventiva o reaproveitamento da água quente que durante a sua utilização por equipamentos externos, gera externamente ao equipamento o condensa mento da água no qual é coletada e bombeada para que a mesma seja reaproveitada enquanto ainda está aquecida, para ser novamente superaquecida e retornar ao sistema de alimentação dos equipamentos externos. Thus the model proposed here was designed with a supplementary changer to harness the energy contained in the condenser, improving the heating capacity of water with less use of combustible material. That is, the present model brings as inventive novelty a system that has as inventive novelty the reuse of hot water that during its use by external equipment, generates externally to the equipment the condensation of water in which it is collected and pumped so that it be reused while it is still heated, to be overheated again and return to the external equipment supply system.

Desta forma autor busca coletar a água que foi convertida de vapor latente para água condensada em alta temperatura e reintroduzir este condensado novamente no sistema reaproveitando a sua energia térmica.  [010] The recuperator exchanger claimed here is an innovation for industries that use the latent heat of steam as energy for equipment operation. Thus, the author seeks to collect water that has been converted from latent steam to condensed water at high temperature and reintroduce this condensate back into the system by reusing its thermal energy.
