Description

Band new and effective horizontal fuel oil of shell-and-tube energy-saving appliance or combustion and steam boiler

(1) technical field

The utility model relates to a kind of boiler.Be specifically related to new and effective horizontal fuel oil of a kind of band shell-and-tube energy-saving appliance or combustion and steam boiler.Belong to the heating equipment technical field.

(2) background technology

For sustainable development and the requirement on environmental protection that adapts to national economy, coal type fuel is progressively changed into oil, gas type fuel.Oil, gas type fuel are easy to carry and use, and are guaranteeing not produce environmental pollution basically under the good burning condition, the calorific capacity height, and this makes fuel oil, gas fired-boiler realize operation automation, high efficiency.In recent years because oil-burning gas-fired boiler is small, automaticity is high, easy for installation, and under various heating agents, can obtain very convenient and use flexibly, oil-burning gas-fired boiler has obtained developing widely and using.

At present, the existing fuel-firing gas-firing Industrial Boiler type of furnace mostly by not being with the energy-saving appliance design, has the band energy-saving appliance also can only acquire mainly based on horizontal three backhaul wetting back-type fire tube structures temporarily.Along with improving constantly that national energy-saving and emission-reduction require, boiler band energy-saving appliance will be an inexorable trend, to reach the purpose that reduces exhaust gas temperature.The domestic correlative study that band energy-saving appliance two return fuel oil (gas) steam boiler is also arranged is illustrated below:

ZL200610085893.X discloses a kind of integral type band energy-saving appliance two return condensing fuel oil, combustion and steam boiler.It mainly is made up of flue, the chamber of strile-bacing, convection tube, integral type coiled pipe energy-saving appliance, shell and front smoke box.Its operation principle is: feedwater adds the heat absorption waste heat through integral type coiled pipe energy-saving appliance, and further heating produces steam in shell, and the shell internal heating surface is two backhauls.This boiler is realized the boiler of efficient operation with very-close-coupled structure.The weak point of this boiler is:

1) conventional art is still used in the chamber of strile-bacing, and strile-backs to use the Drag link stay bolt between chamber back tube sheet and the cylindrical shell back tube sheet, and as Fig. 2, the welding job amount is big;

2) energy-saving appliance is arranged in the front smoke box, is the coiled pipe structure, and water capacity is little, the maintenance difficulty.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of new and effective horizontal fuel oil of band shell-and-tube energy-saving appliance or combustion and steam boiler that the welding of a large amount of Drag links, water capacity are big, be easy to overhaul that need not is provided.

The purpose of this utility model is achieved in that new and effective horizontal fuel oil of a kind of band shell-and-tube energy-saving appliance or combustion and steam boiler, comprise cylindrical shell, flue, the chamber of strile-bacing, convection bank, front smoke box 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, the tube side of convection tube is connected with the front smoke box and the chamber of strile-bacing, burner is arranged at the flue front end, it is characterized in that above described front smoke box, being provided with a shell-and-tube energy-saving appliance, the shell side of this shell-and-tube energy-saving appliance is connected with cylinder lumen, and the tube side of shell-and-tube energy-saving appliance is connected with front smoke box.

Through flue, the chamber of strile-bacing, convection tube tube side and shell-and-tube energy-saving appliance tube side in the cylindrical shell, flue-gas temperature enters atmosphere after dropping to and being lower than 160 ℃ to the flue gas that burner combustion produces successively; Feedwater adds through shell-and-tube energy-saving appliance shell side that heat absorption is laggard goes into cylindrical shell, and further heating produces steam, cylindrical shell internal heating surface flue and convection tube two backhauls in cylindrical shell.Boiler thermal output height, manufacturing process are simple.

Compared with prior art, the utlity model has following advantage:

1) cancels the chamber back tube sheet that strile-backs, no longer welded Drag link.

2) energy-saving appliance adopts the shell-and-tube energy-saving appliance, and water capacity is big, is easy to maintenance.
