Abstract
The utility model discloses a vertical condensation constant-pressure water heating boiler, which belongs to the field of heating equipment. The vertical condensation constant-pressure water heating boiler comprises a burner, a furnace body and a condenser. The condenser is arranged at a position of a flue through which gases pass, the heating surface of the condenser adopts a steel-aluminum composite fin pipe or a stainless steel fin pipe, and water is filled in the fin pipe. Since the condenser adopts the steel-aluminum composite fin pipe or the stainless steel fin pipe as a main heating component, compared with light pipes, the heat transfer area can be enlarged by 5-10 times, the fluid turbulence on the fin surface can be enhanced, the heat transfer coefficient can be increased by once to three times, the utilization rate of heat energy is greatly increased, the thermal efficiency of the boiler is improved significantly, and the emission of harmful substances is reduced.
Description
Technical field
The utility model relates to a kind of boiler, and particularly a kind of condensation normal-pressure hot-water boiler belongs to heat transmission equipment and makes the field.
Background technology
Contain a large amount of protiums during present boiler is fuel used, burning produces a large amount of water vapours.Can produce the 1.55Kg water vapour behind every cubic metre of combustion of natural gas, have the considerable latent heat of vaporization, be approximately 3600KJ/Kg, account for natural gas low heat valve about 10%.When exhaust gas temperature was higher, water vapour can not be condensed, and with fume emission, heat is wasted.Simultaneously, high-temperature flue gas also has a large amount of heats (obvious heat of smoke), and discharging is referred to as flue gas loss together.The main purpose of condensation heating surface is exactly to reduce exhaust gas temperature and the water vapour condensation in the flue gas is got off, absorption portion sensible heat and latent heat, conventional boiler is with most of sensible heat transfer feedwater or steam in the flue gas, and condenser boiler not only feeds water bigger a part of sensible heat transfer or steam, but also absorbed the latent heat of vaporization that discharges behind the water vapor condensation in the partial fume, realize energy recovery, improve the thermal efficiency of steam generator system, the condensing normal-pressure hot-water boiler thermal efficiency improves about 8～15% than the thermal efficiency of ordinary hot homogeneous solution-type reactor, a large amount of energy have been saved, and the emission of harmful substances in the flue gas also significantly reduces, the main condenser that relies on of condenser boiler heat absorption, the shape of condenser and material play crucial effects to the utilization of the thermal efficiency.
Summary of the invention
The utility model is for providing a kind of energy-efficient, better vertical condensation normal-pressure hot-water boiler of condensation effect.
Vertical condensation normal-pressure hot-water boiler provided by the utility model, comprise burner, body of heater and condenser, at flue gas stream through locating to be provided with condenser, the condenser heating surface is steel-aluminum composite fin tube or stainless steel finned tube, the finned tube inboard is a water, water and the water in the body of heater in the finned tube are logical, and burner hearth is arranged vertically, and the smoke pipe district adopts the turbolator heat exchange.
The beneficial effects of the utility model are: with respect to light pipe, the finned tube heat transfer area can increase 5 ~ 10 times, increase the fin surface fluid turbulent, heat transfer coefficient improves 1 ~ 3 times than light pipe, and the water in the condenser in the finned tube and heating system, the interior water of body of heater are and connect, and jumbo hot water passes through condenser, heat exchange is abundant, reclaim a large amount of latent heats of vaporization of water vapour in the flue gas, thereby improve the thermal efficiency of boiler greatly, and reduced emission of harmful substances.
Description of drawings
Accompanying drawing 1 is the structural representation of this device.
The specific embodiment
For better understanding the utility model, the specific embodiment is provided, but the utility model be not subject to concrete must this embodiment.
Be described with reference to the accompanying drawings the specific embodiment of the present utility model, as shown in drawings, burner 1 of the present utility model and body of heater 2 link, condenser 3 is positioned at flue gas stream through the position, for oven body part, burner hearth is arranged vertically, and the smoke pipe district adopts turbolator to strengthen heat convection, upside centralized arrangement, being easy to flue gas collects, maintenance is convenient, flame and flue gas all in body of heater upwards nature walk, running resistance is little, for condenser portion, condenser adopts steel-aluminum composite fin tube or stainless steel finned tube as main heating surface, and the finned tube inboard is a water, communicates by system with water in the body of heater, the high-temperature flue gas that discharge for body of heater in the outside, water with in the high-temperature flue gas heating finned tube reduces exhaust gas temperature, reaches the purpose of energy-conserving and environment-protective.
During the utility model work, condenser adopts steel-aluminum composite fin tube or stainless steel finned tube as main heated element, can increase 5 ~ 10 times with respect to the light pipe heat transfer area, increase the fin surface fluid turbulent, heat transfer coefficient improves 1 ~ 3 times than light pipe, improved the utilization rate of heat energy greatly, water in the condenser in the finned tube and heating system, the interior water of body of heater are and connect, jumbo hot water passes through condenser, heat exchange is abundant, reclaim a large amount of latent heats of vaporization of water vapour in the flue gas, thereby improve the thermal efficiency of boiler greatly, and reduced emission of harmful substances.
