Description
Technical field
The present invention relates to the local structure parts of a kind of fuel-firing gas-firing steam water boiler, the exogenous damp back of the body device of especially a kind of external wet back type fuel-firing gas-firing steam water boiler; The present invention also relates to a kind of boiler, especially a kind of external wet back type fuel-firing gas-firing steam water boiler.
Background technology
Existing fuel-firing gas-firing steam water boiler adopts pan shell type three backhaul to wet back structure usually, stove courage centrosymmetry or arranged off-centre. Fuel pressurized firing in the first backhaul stove courage, high-temperature flue gas along stove courage to after turn back through wetting back-type return combustion chamber and to flow through two return smoke pipe, transferring 180 �� through compression type front smoke chamber enters the 3rd backhaul smoke pipe, eventually passes through the smoke outlet in rear smoke chamber and discharges.
As depicted in figs. 1 and 2, comprising the first backhaul stove courage 1, two return smoke pipe 2 and the 3rd backhaul smoke pipe 3, described first backhaul stove courage 1 and two return smoke pipe 2 are connected existing a kind of fuel-firing gas-firing steam water boiler by little smoke-box 4. This kind of fuel-firing gas-firing steam water boiler radiation heating surface all adopts little smoke-box (the interior wet back of the body) structure to the excessive section of convection heating surface, its structure design must form red flame (fuel oil) radiation heating surface deficiency and blue flame (combustion gas) radiant-type furnace courage curtailment, and what bring is exactly that flue gas temperature of hearth outlet is higher. When flue gas temperature of hearth outlet is higher, or increase convection heating surface, steel quantity consumption can be made like this to increase; Boiler body funnel temperature is higher, and the boiler thermal output being so just reduces. Simultaneously because above-mentioned reason and tube sheet can cause flue gas circulating resistance bigger with smoke pipe employing Type of Welding.
Existing another kind of fuel-firing gas-firing steam water boiler, as disclosed in Chinese utility model patent that publication number is CN2292245Y, which employs a kind of exogenous damp back structure with water wall so that flue gas is cooled with smoke box after protecting at water wall. But this kind of structure comparison complexity, and need to take bigger volume.
Summary of the invention
Technical problem to be solved by this invention is to provide the exogenous damp back of the body device of a kind of fuel-firing gas-firing steam water boiler, and a kind of fuel-firing gas-firing steam water boiler, make fuel-firing gas-firing steam and hot water pot furnace structure simpler, it is convenient to processing safeguard, and improves the efficiency of fuel-firing gas-firing steam water boiler.
For solving the problems of the technologies described above, the technical scheme of the exogenous damp back of the body device of fuel-firing gas-firing steam water boiler of the present invention is, comprise smoke-box, described smoke-box is by being positioned at the exogenous damp penstock plate before smoke-box, it is positioned at smoke-box two sides backboard wet with side below and it is positioned at and surround with wet backboard above after smoke-box and become, described interior wet backboard skin is also provided with exogenous damp backboard, the housing of described exogenous damp backboard and boiler is surrounded as room, a chamber, described chamber chambers contain smoke-box, described smoke-box internal space is connected with the first backhaul stove courage and the two return smoke pipe of boiler, cavity space outside described smoke-box is filled by water to be heated in boiler.
Invention further provides a kind of fuel-firing gas-firing steam water boiler, its technical scheme is, being arranged with the first backhaul stove courage, two return smoke pipe and the 3rd backhaul smoke pipe that head and the tail S shape connects in boiler from top to bottom in parallel, described first backhaul stove courage is connected by the exogenous damp back of the body device of above-mentioned fuel-firing gas-firing steam water boiler with two return smoke pipe.
The present invention, by adopting above-mentioned exogenous damp back structure, reduces fuel consumption and improves boiler thermal output, reduce running cost. Exogenous damp back structure can avoid flame directly to wash away heating surface in addition, and simultaneously interior wet backboard is separated by this structure with exogenous damp backboard, makes the steel plate fatigure failure that boiler back tube plate operationally can not produce temperature stress and causes, greatly improves boiler life.

Embodiment
The present invention discloses the exogenous damp back of the body device of a kind of fuel-firing gas-firing steam water boiler, as shown in Figure 3 and Figure 4, comprise smoke-box 5, described smoke-box 5 is by being positioned at the exogenous damp penstock plate 6 before smoke-box, it is positioned at smoke-box two sides backboard 7 wet with side below and it is positioned at and surrounded with wet backboard 8 above after smoke-box, described interior wet backboard 8 skin is also provided with exogenous damp backboard 9, described exogenous damp backboard 9 is surrounded as room, a chamber with the housing of boiler, described chamber chambers contain smoke-box 5, described smoke-box internal space is connected with the first backhaul stove courage and the two return smoke pipe of boiler, cavity space outside described smoke-box is filled by water to be heated in boiler.
As shown in Figure 4, described smoke-box 5 bottom is the arc corresponding with boiler casing shape.
As shown in Figure 3, the upper side section of described interior wet backboard 8 and exogenous damp backboard 9 is arc.
Shown in composition graphs 3 and Fig. 4, post 10 is connected with boiler housing and exogenous damp backboard 9 by connecting for the wet backboard 7 in described side and interior wet backboard 8, thus fixes indoor in chamber for described smoke-box 5.
The invention also discloses a kind of fuel-firing gas-firing steam water boiler, as shown in Figure 3 and Figure 4, being arranged with the first backhaul stove courage 1, two return smoke pipe 2 and the 3rd backhaul smoke pipe 3 that head and the tail S shape connects in boiler from top to bottom in parallel, described first backhaul stove courage 1 is connected by the exogenous damp back of the body device of above-mentioned fuel-firing gas-firing steam water boiler with two return smoke pipe 2.
Described two return smoke pipe 2 is arranged on the top or around of described first backhaul stove courage 1, or top and around.
The present invention adopts the exogenous damp back of the body device of above-mentioned fuel-firing gas-firing steam water boiler, when making boiler overall volume constant, first backhaul stove courage can take longer space, so that fuel burns more fully, and the flue gas burnt heat exchange abundant with water to be heated in the exogenous damp back of the body device of described fuel-firing gas-firing steam water boiler, thus improve the efficiency of fuel-firing gas-firing steam water boiler.
Fuel-firing gas-firing steam water boiler provided by the present invention, when boiler total length is identical, owing to exogenous damp carries on the back apparatus structure closely, therefore the length of stove courage is made to lengthen, not only add radiation heating surface, the length of flame is conducive to launch, for the abundant after-flame of fuel provides condition, and make two return input gas temperature relative reduction 30-50 DEG C, combine with the back of the body wet in arc and exogenous damp back structure, reduce flue gas backhaul resistance 5-10 millimeter water column further, thus reduce fuel consumption, improve boiler thermal output, burner fan efficiency is thus also brought to improve and the increase of burner type selecting face, the power of fan of coupling is needed to reduce, reduce running cost. the exogenous damp back structure lengthened in addition can avoid flame directly to wash away heating surface, and simultaneously interior wet backboard is separated by this structure with exogenous damp backboard, makes the steel plate fatigure failure that boiler back tube plate operationally can not produce temperature stress and causes, greatly improves boiler life.
