The following describes operation of the present invention with above-mentioned structure.
The fuel (oil or gas) that injects from burner (B) burns at combustion chamber (5), rises via toxic emission passage (5a), and accumulates in the toxic emission chamber (5c) by waste gas outlet (5b), discharges via flue (5d) then.Because the intensive interior water pipe group (3A) that forms of the confined space that is arranged in combustion chamber (5) of flat horizontal water pipe (3), height through the toxic emission passage (5a) that close clearance constituted between the horizontal water pipe (3) is directly contacted with the surface of horizontal water pipe (3) well with flame by hot combustion gas, thereby realizes that by the surface of horizontal water pipe efficient heat receives operation.Although the heat receiving area of horizontal water pipe (3) increases, the amount of water is very little in the horizontal water pipe (3), and therefore, water (w) is heated fast, causes the internal pressure of horizontal water pipe (3) to raise.Therefore, hot water is circulated to level water pipe group (3An) by water channel (3r) fast from following level water pipe group (3A), and flows into the top of water cavity (2) with the heat that increases.In the bottom of water cavity (2), the high temperature of water is kept along with level water pipe group (3A) under the water inflow.Hot water is fed to the outside via feed pipe (p, p '), and cooling water flows back to water cavity (2) via water inlet (K).
Burning gases are introduced the core of toxic emission passage (5a) by guide plate (4d).Although (5a) is narrow for the toxic emission passage, but make its even distribution, thereby when keeping the good combustion operation, reduce exhaust resistance with straight grid lines.In addition, toxic emission chamber (5c) is by forming than the wideer space of toxic emission passage (5a), and then postponed the discharging of the burning gases of inflow exhaust gas discharge chamber (5c), and during this period, the after-heat that is contained in the burning gases is reclaimed by top water cavity (2b) at last.This has obviously reduced the loss via the heat energy of flue (5d) discharge.
In addition, owing to arrange toxic emission passage (5a), therefore, water jet can be placed in the combustion chamber (5) in order to injecting water with straight grid lines, thus dirt and dust that cleaning is heaped as far as the superiors' level water pipe groups (3An).Clean the dirt and the dust of horizontal water pipe (3), the heat of having kept water pipe well receives operation, thereby improves the performance of boiler.Because the water that is used to clean is discharged via discharge outlet (d), therefore, can clean boiler well.
Industrial applicibility
In boiler according to the present invention, a plurality of flat horizontal rectangular water tubes are arranged in water pipe up and down thick and fast around being communicated with inner water cavity in the confined space of the combustion chamber that forms.Therefore, the heat receiving area of horizontal water pipe is greater than the amount of water in the horizontal water pipe, and this makes that can receive operation by the heat of horizontal water pipe carries out Fast Heating to the water in the horizontal water pipe.
In addition, because the toxic emission passage is formed by the close clearance between the horizontal water pipe, therefore, the burning gases of flame that highly is heated and process toxic emission passage contact well with the surface of horizontal water pipe and realize that efficient heat receives operation, thereby improve the heat energy utilization rate of boiler.
In addition, most of heat of the burning gases of being discharged was recovered before the burning gases of being discharged arrive the toxic emission chamber.Because burning gases are postponed via the discharge of flue, thereby reclaim after-heat by the top water cavity at last when inflow exhaust gas discharge chamber.At this moment, because the temperature of the burning gases of discharging via flue is no more than 100 ℃ to 200 ℃, therefore, for watertube boiler, heat energy recovery rate is very high.
