Abstract
The utility model discloses a round fuel oil/fuel gas vacuum water heater unit, which comprises a burner, a unit body, a built-in heat exchanger, a vacuum pressure meter, a rupture disk, a front smoke box, a rear smoke box, a smoke outlet, a water outlet and a return water inlet; the unit body is of a horizontal internal combustion three-pass full wet back type structure, and both the unit body and the unit are round; the heat exchanger is arranged in the upper part of the boiler, and both ends of the heat exchanger are provided with detachable end enclosures. Since the unit body adopts the horizontal internal combustion three-pass full wet back type structure and a corrugated furnace which can absorb heat to expand is adopted as the furnace, the heat efficiency of the unit is larger than or equal to 92 percent; since both the unit body and the unit are of the round structures and do not need to be disassembled, the wholeness of the shape is strong, the layout is compact, and the style is beautiful; both the front and the rear smoke boxes are of detachable structures, so the unit body can be conveniently overhauled; since the heat exchanger is arranged in the upper part of the boiler and both ends of the heat exchanger are provided with the detachable end enclosures, heat exchange tubes can be conveniently dismounted and replaced; and because intelligent man-machine conversation control is adopted to control the unit, the operation is simple.
Description
Technical field
The utility model relates to a kind of fuel-firing gas-firing hot water unit.
Background technology
At present, the cigarette system of hot water unit is dried back of the body formula structure, this cigarette system process complexity, and heating surface area is little, flue bulk strength deficiency, tube sheet causes weld cracking because of the thermal deformation meeting, and the flue gas sealing difficulty is big, and air leakage coefficient is big, and the thermal efficiency is low; Existing in addition gas and hot water unit body is an oval shape, and profile then is square, wants plug-in panel mask in the outside of front and back smoke box, exchanger head; Need take panel earlier apart during maintenance, also inconvenient when causing the cost of overhaul; Also increase cost; Also be not easy to change.
The utility model content
The utility model purpose is to provide a kind of thermal efficiency height; Convenient and the integral layout compactness of body maintenance and replacing, a kind of cylinder type fuel-firing gas-firing vacuum hot water unit that the outside is beautiful.
The technical solution of the utility model is: comprise combustor, body body, built-in heat exchanger, pressure vacuum gauge, burst disk, front and back smoke box, exhanst gas outlet; Delivery port; Water return outlet; It is characterized in that described unit body is the full wetting back-type structures of horizontal internal combustion three backhauls, unit body and unit external form are round; Described heat exchanger places upper boiler, and the heat exchanger two ends are provided with removable end socket.
Described flue is a corrugated internal furnace.
Described burner hearth rear portion is provided with the inspection door of explosion prevention function.
The smoke box body of described front and back smoke box is that hinge is connected with smoke box door, constitutes removable structure.
The body body is provided with interactive Based Intelligent Control.
The utility model unit body adopts the full wetting back-type structure of horizontal internal combustion three backhauls, and flue adopts corrugated internal furnace to absorb thermal expansion, so generatine set heat efficiency 〉=92%; Unit body and unit external form are round structure, need not dismantle, and the shape integral sense is strong, and compact in design is attractive in fashion; , the front and back smoke box is removable structure, and the body maintenance is convenient; Heat exchanger places upper boiler, and two ends are provided with removable end socket, and heat exchanger tube splits out to be changed conveniently; Interactive Based Intelligent Control is adopted in unit control, and is simple to operate.
