Recent two decades comes, and on the one hand, the development rate of oil, natural gas improves greatly, and country has cancelled the restriction that large-and-medium size cities use oil product and natural gas; On the other hand along with the enhancing of global environmental consciousness, Chinese national economy develops rapidly, living standards of the people improve constantly, China adjusts the fuel policy, be environmental pollution and the air quality of improving large-and-medium size cities, government begins to encourage public enterprises and institutions to use oil product or natural gas, has accelerated the development of oil-burning gas-fired boiler greatly.
In the development of fuel-firing gas-firing Industrial Boiler, the fuel-firing gas-firing Industrial Boiler type of furnace that China mainly produces is horizontal three backhaul wetting back-type fire tube structures, 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 manufacturer and 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 is because of being subjected to the restriction of its structure, and boiler thermal output is generally at 88%-91%, and exhaust gas temperature is higher than saturation temperature, is generally 220-260 ℃, and this exhaust gas temperature is very uneconomic for boiler.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 has caused bigger waste also for oil, the gas resource of China.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of under the prerequisite that keeps tight, little, whole, the few advantage of horizontal three backhaul wetting back-type multitubular boilers, further improve boiler thermal output, reduce the integral type band energy-saving appliance three backhaul fuel-firing gas-firing steam boilers of exhaust gas temperature.
The purpose of this utility model is achieved in that a kind of integral type band energy-saving appliance three backhaul fuel-firing gas-firing steam boilers, comprise shell, flue, the chamber of strile-bacing, front smoke box, back smoke box, the second backhaul convection tube and the 3rd backhaul convection tube, described flue, the chamber of strile-bacing, the second backhaul convection tube and the 3rd backhaul convection tube all are arranged in the shell, flue is horizontally placed on bottom in the 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 shell front side, back smoke box is arranged at the shell rear side, the second backhaul convection tube and the 3rd backhaul convection tube are horizontally placed on the shell internal upper part, the tube side of the second backhaul convection tube is connected with strile-back chamber and front smoke box, the tube side of the 3rd backhaul convection tube is connected with front smoke box and back smoke box, be provided with the coiled pipe energy-saving appliance at smoke box top, described back, be provided with exhaust pass at coiled pipe energy-saving appliance top, the shell side of coiled pipe energy-saving appliance is connected with back smoke box and exhaust pass.
The utility model integral type band energy-saving appliance three backhaul fuel-firing gas-firing steam boilers, described coiled pipe energy-saving appliance heating surface is a light pipe, and by arranging along row.
The utility model integral type band energy-saving appliance three backhaul fuel-firing gas-firing steam boilers, described back smoke box adopts bolt to be connected between the two with the coiled pipe energy-saving appliance, and is detachable.
The flue gas that burner combustion produces is successively through flue, the chamber of strile-bacing, the second backhaul convection tube, front smoke box, the 3rd backhaul convection tube, coiled pipe energy-saving appliance, back smoke box and exhaust pass, enters atmosphere after dropping to 160 ℃.Realized the lower temperature discharging of the simplification of flow process, horizontal steam boiler flue gas, improved boiler thermal output, improved about 3 percentage points than three times traditional horizontal tubular boiler thermals efficiency.The shell internal heating surface is three backhauls.Realize efficient operation with very-close-coupled structure, application widely.
The beneficial effects of the utility model are:
The utility model has further improved boiler thermal output under the prerequisite that keeps tight, little, whole, the few advantage of horizontal three backhaul wetting back-type multitubular boilers, reduced exhaust gas temperature.
