Problems solved by technology

[0004] CN201720498910.6 discloses a condensing boiler with an atmospheric boiler plus a condenser unit. The way of adding a condenser cannot realize integrated condensation, which significantly increases the side resistance of the flue gas, makes the waterway more complicated, and increases the number of failure points
CN201810668419.2 discloses a coil-type condensing boiler. The burner is placed in the center of the coil, and the flue gas flows to the surroundings. There is a risk of carbon deposit

Example Embodiment

[0033] The invention will be described in detail below with reference to the drawings and specific embodiments.

[0034] Such as figure 1 in Figure 1a , Figure 1b with figure 1 As shown in c, a tube-type gas condensing boiler of the present invention, the boiler body consists of a round tube water wall 1-1, a radiation cooling section 1-2, a convection cooling section 1-3, a deep cooling section 1-4, and a deep condensing section 1. -5. Fully premixed burner 1-6, dew plate 1-7, inlet and outlet side shell 1-8, turning side shell 1-9, etc. The materials can be austenitic stainless steel 304L, 316L, etc., ferritic stainless steel 430, 434, etc., extruded aluminum 6000 series, etc. The high-temperature flue gas generated after the ignition of the fully premixed burner 1-6 washes the round pipe water wall 1-1 and the radiation cooling section 1-2, and then passes through the convection cooling section 1-3, the deep cooling section 1-4, and the deep condensation section in sequence ...

Abstract

The invention discloses a tubular gas condensing boiler and system. A boiler body is composed of a round tube water cooling wall, a radiation cooling section, a convection cooling section, a deep cooling section, a deep condensation section, a full pre-mix burner, a dew bearing disc, an inlet and outlet side shell body, a steering side shell body and the like, and a water way system coupled by theboiler and a water source heat pump is composed of a condensation section inlet, a condensation section outlet, a convection section inlet, a radiation section outlet, the water source heat pump, a water pump, a plate-type heat exchanger, a pressure stabilizing tank, a three-way valve and the like. The boiler adopts integrated condensation design, the convection and condensation parts adopt the small-section layer-flow reinforced design concept, the boiler rated thermal efficiency can be over 103%, and the boiler rated thermal efficiency after coupling with the heat pump can be over 110%.

Description

technical field [0001] The invention relates to the field of gas-fired boilers, in particular to a tube-type gas-fired condensing boiler and a system using stainless steel and extruded aluminum as materials. Background technique [0002] In recent years, the problem of smog has persisted, and it has become more frequent after entering the heating season. In order to control smog and protect the blue sky, the heating industry has put forward the "Winter Clean Heating Plan in Northern China 2017-2021", which requires that by 2021, the clean heating rate will be 70%, and clean energy will replace 150 million tons of scattered coal for heating. In 2016, the natural gas consumption for heating in winter reached 36.3 billion m 3 , it is estimated that by 2021, the heating gas consumption will reach 64 billion m 3 above. Natural gas boiler heating replaces scattered coal heating, resulting in a continuous shortage of natural gas for heating in winter. By 2021, natural gas heatin...
