Description
Technical field:
The present invention relates to a kind of boiler.Be specifically related to a kind of integral type band energy-saving appliance two return condensing fuel oil, combustion and steam boiler.Belong to the heating equipment technical field.
Background technology:
Boiler is a kind of heating equipment.It is to utilize coal, oil or gas to be fuel, produces heat through burning and produces steam.Flue gas, slag that coal type fuel produces pollute the environment, the harm people health, and also combustion technology and flue gas are handled comparatively complicated.Oil, gas type fuel are easy to carry and use, and are guaranteeing not produce environmental pollution basically, the calorific capacity height under the good burning condition.In recent years because oil-burning gas-fired boiler is small, automaticity is high, easy for installation, and under various heating agents, can be able to very convenient and use flexibly.
The most typical type of furnace of fuel-firing gas-firing Industrial Boiler in the past is horizontal three backhaul wetting back-type fire tubes, and its structure is seen Fig. 1.Mainly form by flue 1, the chamber 2 of strile-bacing, the first return-stroke type convection tube 3, cylindrical shell 4, front smoke box 6, burner 7, the second return-stroke type convection tube 8 and back smoke box 9.Convection tube has two groups, and the cylindrical shell internal heating surface is flue and two groups of convection tube three backhauls.Energy-saving appliance is in addition outside boiler.Dispatch from the factory, take up an area of less because of its compact conformation, volume are little, self-contained, the automaticity height, be subjected to user's favor, " horizontal three backhaul wetting back-type multitubular boilers " have almost become the synonym of fuel oil, gas fired-boiler.But this kind boiler structurally still has following deficiency:
1, energy-saving appliance is in addition outside boiler, complex structure, loose.
2, the cylindrical shell internal heating surface is flue and two groups of convection tube three backhauls, and flow process is comparatively complicated.
Because of being subjected to the restriction of its structure, boiler thermal output is generally 88%～91%, and exhaust gas temperature is higher than saturation temperature, is generally 220 ℃～260 ℃.This exhaust gas temperature is very uneconomic for boiler, and the exhaust gas temperature of coal-burning boiler is generally about 160 ℃.Large-scale use along with this boiler type of furnace has replaced coal-burning boiler to a great extent, improves the environmental pollution and the air quality of large-and-medium size cities, but also oil supply, gas resource have caused bigger waste.
In order to reduce exhaust gas temperature,, generally be outside boiler body 10, to add a joint energy-saving appliance 5 in addition as shown in Figure 2 at horizontal three backhaul wetting back-type multitubular boilers.This configuration mode makes that the boiler overall structure is more open.
Under the prerequisite that keeps tight, little, whole, the few advantage of horizontal three backhaul wetting back-type multitubular boilers, whether can further improve boiler thermal output, reduce exhaust gas temperature?
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, a kind of thermal efficiency height, exhaust gas temperature integral type band energy-saving appliance two return condensing fuel oil, combustion and steam boiler low, simple and compact for structure are provided.
The object of the present invention is achieved like this: integral type band energy-saving appliance two return condensing fuel oil, the combustion and steam boiler, it is characterized in that it comprises: cylindrical shell, flue, the chamber of strile-bacing, convection tube, front smoke box, coiled pipe energy-saving appliance and burner, described flue, strile-back chamber and convection tube all is arranged in the cylindrical shell, flue is horizontally placed on bottom in the cylindrical shell, the chamber of strile-bacing is arranged at the flue rear side, with the flue intracavity inter-connection, front smoke box is arranged at the outer front upper side of cylindrical shell, convection tube is horizontally placed on the cylindrical shell internal upper part, be connected with the front smoke box and the chamber of strile-bacing, the coiled pipe energy-saving appliance is arranged in the front smoke box, is connected with cylinder lumen, and burner is arranged at the flue front end.
The flue gas that burner combustion produces is successively through the coiled pipe energy-saving appliance in flue, the chamber of strile-bacing, convection tube and the front smoke box in the cylindrical shell, and partial fume produces condensation, and temperature enters atmosphere after dropping to and being lower than 160 ℃; Feedwater enters cylindrical shell after adding the heat absorption waste heat through the coiled pipe energy-saving appliance, and further heating produces steam in cylindrical shell, and the cylindrical shell internal heating surface is flue and convection tube two backhauls, realizes efficient operation with very-close-coupled structure.
Compare with three return-stroke type multitubular boilers in the past, the present invention has following characteristics:
1, be provided with the coiled pipe energy-saving appliance in the front smoke box, coiled pipe energy-saving appliance and boiler body are incorporated into one, absorb flue gas heat, and be simple and compact for structure.
2, cancelled the convection tube of the 3rd journey, utilize energy-saving appliance working medium temperature low, with the big characteristics of the flue gas temperature difference, absorbed the heat that absorbs more than former the 3rd backhaul convection tube with less heating surface, realized the discharging of the lower temperature of the simplification of flow process and horizontal steam boiler flue gas, improved boiler thermal output, improved 3～5 percentage points than in the past the three return-stroke type multitubular boiler thermals efficiency.Simplify the structure simultaneously, saved the steel consumption.
