Description

Vertical fuel oil (coal) heat pipe hot water boiler

The utility model provides a kind of vertical fuel oil (coal) heat pipe hot water boiler, and belonging to has the fluid heater of heat generator preparing technical field.

Used boiler in the industrial production or in the civilian heating, most of hot-water boilers are calandria structures of strengthening convection current.Boiler oil consumption (coal) amount of this structure is big, and thermal conversion efficiency is low, and programming rate is slow, the exhaust gas temperature height.

For solving the deficiency of above four aspects, the invention provides that a kind of oil consumption (coal) amount is little, thermal conversion efficiency is high, quick heating, vertical fuel oil (coal) heat pipe hot water boiler that exhaust gas temperature is low.

Elaborate below in conjunction with the vertical fuel oil of accompanying drawing (coal) heat pipe hot water boiler:

Accompanying drawing 1 is the vertical fuel oil of the utility model (coal) heat pipe hot water boiler vertical section schematic diagram.

The structure of vertical liquid fuel (coal) heat pipe hot water boiler be by base [1], silk seat [2], Foundation ring [3], burner port [4], combustion chamber [5], heat pipe [6], lower perforated plate [7], urceolus Body [8], upper hose [9], rib-loop smoke pipe [10], low temperature water tank [11], upper inferior horn circle [12], upper perforated plate [13], smoke-box girth sheets [14], upper sieve bolt [15], spoiler [16], Acidproof smokejack [17], upper water seat [18], backwater base [19] and look fire hole [20] and form. Pot The stove outer cylinder body is the garden tubular, and combustion chamber [5] connect with the inferior horn lap welding with outer cylinder body [8], and descend The angle circle is united with base [1] welding again, and angle circle [12] and upper pipe are used in outer cylinder body [8] upper end Plate [13] welding is united, and forms the water jacket boiler of two-layer body, and burning is formed at the bottom in the water jacket Chamber [5], and the loam cake of combustion chamber [5] is lower perforated plate [7] by several rib-loop smoke pipes by lower Tube sheet [7] and the welding of upper perforated plate [13] two ends, the calory burning passage of formation boiler, on A garden shape low temperature water tank [11] is welded and the top of several rib-loop smoke pipes in the bottom of tube sheet [13] By low temperature water tank [11], water tank upper welding upper hose [9], upper hose [9] vertically by Upper and lower until lower perforated plate [7] is equipped with several vertical super heat-conductive pipes in the water jacket around the boiler [6], and sentence in 35 ° of insertion combustion chambers, angles [5] lower end 1/4th of heat pipe [6], The interface seal welding, cigarette in top welding smoke-box girth sheets [14] formation of Shang Jiaoquan [12] The chamber is fastened on the smoke-box girth sheets [14] with sieve bolt and smokejack base plate [17] adds asbestos pad, Form complete vertical heat water boiler structure. This boiler belongs to efficient, energy-conservation Novel pot Stove. Its characteristics:

1, heat pipe effect: several super heat-conductive pipes [6] are housed in the water pipe of boiler border, 1/4 place, lower end of heat pipe is welded in the combustion chamber, and the heating surface area with 1/4 obtains 3/4 The isothermal radiation area. After making ignition of the boiler, stove water heats up rapidly.

The present invention is with 40 * 10 ⁴The boiler of Kcal/n is an example: water capacity is 1380Kg, and the 10 minutes stove water of lighting a fire reaches 95 ℃, and miniature boiler can reach 95 ℃ in 8 minutes.

2, twice temperature difference is subjected to thermal technology: the general character of boiler is: the fuel high-temperature region is at boiler bottom, and the high-temperature region of water is at the top of boiler, and when fuel heat was up, because the water temperature of upper boiler is too high, it was few to absorb heat, and the heat loss of discharge increases.The exhaust gas temperature of vertical boiler is generally 260～310 ℃.

This boiler structure is: with circulating pump backwater (relatively water at low temperature) is squeezed into the low temperature water tank [11] at boiler top, absorb the principle of heat with the temperature difference.The heat absorption that will discharge.Heat is by behind the low temperature water tank, and exhaust gas temperature is generally all below 120 ℃.

3, scouring type upper hose [9] upper boiler water tank [11] is closed water tank, and after water at low temperature was squeezed into low temperature water tank [11] and made, low temperature water tank was heated.By upper hose [9] water is sprayed on the highest lower perforated plate of boiler heat load [7] again.Oxygenous bubble is washed and changes water, prevent oxide etch smoke pipe and tube sheet.2. prevent that because of water flow velocity is low excessively tube sheet produces Cold Boiling and rises and fouling, stress is concentrated and is caused the bridge cracking.3. after reaching boiler blow-down water, keep water temperature in the stove, the purpose of no significant hypothermal.

4, make things convenient for boiler to repair: to go up smoke-box cover plate and furnace bottom plate washer and adopt sieve bolt fastening means.At any time demolition when boiler is repaired and cleared up.
