Description
Technical field
The invention belongs to field of boilers, relate generally to a kind of vertical fuel oil, combustion gas automatic steam boiler that improves steam-water separation structure.
Background technology
Boiler is a kind of heating equipment, it is to utilize coal, oil gas, living beings etc. to be fuel, produce steam, hot water or other thermal medium through the heat that burning produces, thereby satisfy all kinds of demands in the social production, the flue gas meeting serious environment pollution that coal burning produces, harm humans healthy, and combustion technology and flue gas are processed more complicated; The biomass fuel calorific value is excessively low, and it is larger that layout of boiler takes up an area the space; Fuel-oil or fuel-gas boiler, fuel are easy to carry and use, and the combustion product environmental pollution is minimum, and calorific value is very high, and with respect to the boiler of other fuel type, its volume is very little, it adopts automatic burning equipment simultaneously, makes its automaticity high, but unmanned.
Small fuel oil, gas industry boiler often adopted horizontal three return stroke wet back type multitubular boilers and three novel return stroke vertical through-flow water-tube boilers in the past.Compact conformation, volume littlely, self-contained dispatch from the factory, take up an area less although horizontal three return stroke wet back type multitubular boilers have, the automaticity advantages of higher, but three novel return stroke vertical through-flow water-tube boilers are more outstanding than the former in these areas, therefore in a lot of big cities, exactly because the advantage of the novel three return stroke vertical through-flow water pipe steam boilers of a large number of users and order one after another this kind of boiler.
Its structure is mainly separated header A1, carbonated drink separation dividing plate A2, heating surface tube A3, upper, annular header A4, lower annular header A5, combustion chamber A6, burner A7, corrugated sheet A8 and steam trap connection A9 by secondary carbonated drink and is formed as shown in Figure 1 and Figure 2.Heating surface tube A3 and burner and furnace bottom form combustion chamber A6, and convection section has two backhauls, and the first backhaul is the inner ring of heating surface tube A3 and the exhaust gases passes between the centre circle, and the second backhaul is the centre circle of heating surface tube A3 and the exhaust gases passes between the outer ring.Arranged carbonated drink separation dividing plate A2 among the upper, annular header A4, the steam that produces among the heating surface tube A3 collects in the upper, annular header A4, steam runs into the deadening that carbonated drink is separated dividing plate A2, separate dividing plate A2 both sides from carbonated drink and detour and enter secondary carbonated drink through the steam connection tube on the upper, annular header A4 and separate the header A1, supply with again the user after the separation via corrugated sheet A8 and use.
But also there is following weak point in above-mentioned novel three return stroke vertical through-flow water pipe steam boilers:
1, because the reason of boiler structure, can't arrange enough carbonated drink separation equipments in this kind of upper boiler annular header, this kind of boiler requires characteristics of compact layout simultaneously, it is large and complicated that secondary separation device also can not be arranged, thereby cause this kind of boiler steam-water separation effect not good, other steam boiler of arranging sufficient carbonated drink separation equipment is higher relatively for steam moisture;
2, the steam trap connection in the outside water separator is that high-temperature water is directly drained, and does not add effective utilization, and boiler efficiency is decreased.
Summary of the invention
In order to overcome defects, the invention provides the vertical automatic steam boiler of a kind of carbonated drink divergence type fuel-firing gas-firing, the vertical automatic steam boiler of this carbonated drink divergence type fuel-firing gas-firing is not changing on the integrally-built basis of original boiler, inside and outside to boiler is improved appropriately, the carbonated drink separative efficiency of boiler is improved, simultaneously can utilize again isolated high-temperature water in the steam that emits, improve boiler efficiency, also realize energy-saving and emission-reduction.
