Abstract

The utility model discloses a horizontal type condensing normal pressure hot water boiler, belonging to the field of heat exchange equipment. The horizontal type condensing normal pressure hot water boiler comprises a burner, a boiler body, a condenser and a front smokebox, wherein the condenser is arranged at the position which the flue gas flows through, a steel-aluminum composite finned tube or a stainless steel finned tube is arranged on the heating surface of the condenser, water is filled at the inner side of the finned tube, and a reversal chamber of the front smokebox adopts the water cooling mode. Compared with the bare pipe, the heat transfer area of the finned tube is increased by 5 times to 10 times thereby greatly improving the thermal efficiency of the boiler and reducing the emission of harmful substances, the temperature of the front smokebox is low, the service life is long, and the maintenance workload is low; the 8-shaped reversal chamber is used, so that the boiler has better heat exchange effect through the functions of entrainment and turbulence; and threaded pipes are used for convection heat transfer in a smoke pipe area, and the threaded pipes are centralized at the upper part of the smoke pipe area so as to be easy to collect the flue gas and maintain.

Description

Horizontal condensation normal-pressure hot-water boiler
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 horizontal condensation normal-pressure hot-water boiler of condensation effect.
Horizontal condensation normal-pressure hot-water boiler provided by the utility model, comprise burner, body of heater, condenser and front smoke box, 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-cooled is adopted in the front smoke box chamber of strile-bacing, and the water in the finned tube leads to water in the body of heater.Strile-back in burner hearth employing center.
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, water and heating system in the condenser in the finned tube, water in the body of heater is series connection, 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, the front smoke box chamber of strile-bacing is a full water cooling formula structure, with respect to the generic central boiler that strile-backs, the front smoke box temperature is low, long service life, advantages such as maintenance workload is little, adopt the figure of eight chamber of strile-bacing, entrainment action of turbulent flow, make the heat exchange better effects if, the smoke pipe district adopts the screwed pipe heat convection, the upside centralized arrangement is easy to flue gas and collects, and maintenance is convenient.
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 the body of heater rear portion, for oven body part, the burner hearth form of strile-bacing in the employing center, smoke box is positioned at the body of heater front portion, and front smoke box 4 chamber of strile-bacing is a full water cooling formula structure, with respect to the generic central boiler that strile-backs, the front smoke box temperature is low, have long service life, advantage such as maintenance workload is little adopts the figure of eight chamber of strile-bacing, entrainment action of turbulent flow, make the heat exchange better effects if.The smoke pipe district adopts the screwed pipe heat convection, and the upside centralized arrangement is easy to flue gas and collects, and maintenance is convenient.For condenser portion, condenser adopts steel-aluminum composite fin tube or stainless steel finned tube as main heating surface, the finned tube inboard is a water, communicate by system with the water in the body of heater, the high-temperature flue gas that discharge for body of heater in the outside, with the water in the high-temperature flue gas heating finned tube, realized 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 and heating system in the condenser in the finned tube, water in the body of heater is series connection, 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, the front smoke box chamber of strile-bacing is a full water cooling formula structure, with respect to the generic central boiler that strile-backs, the front smoke box temperature is low, long service life, advantage such as maintenance workload is little.Adopt the figure of eight chamber of strile-bacing, entrainment action of turbulent flow, make the heat exchange better effects if.The smoke pipe district adopts the screwed pipe heat convection, and the upside centralized arrangement is easy to flue gas and collects, and maintenance is convenient.
