Abstract
A hot water boiler of preheated boiler cylinder is prepared as setting boiler cylinder with flue and heat absorber in combustion chamber independently and relatively, setting water outlet and inlet at top and bottom of boiler cylinder and setting water outlet and inlet at top and bottom of heat absorber in combustion chamber then connecting water outlet of boiler cylinder to water inlet of heat absorber in combustion chamber.
Description
Technical field
The present invention relates to a kind of industrial hot water boiler's technical field, especially relate to a kind of industrial water-fire tube hot water boiler that has the smoke pipe drum.
Background technology
Industrial hot water boiler's structure on the market is various, but a common principle is arranged: water at low temperature directly or indirectly enters earlier the heating of boiler furnace high temperature, and the water that obtains temperature heats with the low-temperature flue gas of drum smoke pipe again.The boiler of structural principle has two shortcomings: 1. because water at low temperature enters boiler furnace, can reduce chamber temperature, be unfavorable for the abundant burning of fuel, the dispensing of influence heat like this.2. the water that obtains temperature is again by the flue gas heating of low temperature, because both have a narrow range of temperature, the exchange rate of heat is low, and very big a part of heat can not be absorbed by water, and has been discharged to atmosphere with flue gas.Present boiler, exhaust gas temperature are all very high, and the utilization rate of heat is low, and the BTHE of industrial hot water boiler's heat is below 75%.
Summary of the invention
I am through years of researches, and constantly test has designed successfully the cylinder preheating type industrial hot water boiler.Its manufacture craft is simple, and boiler volume is constant, the manufacturing cost of the existing boiler that do not raise basically, and the thermal efficiency can improve 8 percentage points.This technology can be widely used in various industrial water-fire tube hot water boilers, steam boiler, reaches industrial combustion gas, oil burning boiler, and DEVELOPMENT PROSPECT is very wide.
The technical scheme of cylinder preheating type hot water boiler provided by the invention is:
Cylinder preheating type hot water boiler, form by heat dump in drum that has smoke pipe and the combustion chamber, it is characterized by: a dividing plate is set under the drum internal flue, drum is divided into upper drum district and lower drum district, the top in upper drum district has upper drum district delivery port, and the bottom in upper drum district has upper drum district water inlet; The lower drum district has lower drum district delivery port; The bottom of heat dump has heat dump water inlet in the combustion chamber in the combustion chamber; And the heat dump water inlet is connected in upper drum district delivery port and the combustion chamber, and the top of heat dump and lower drum district are connected in the combustion chamber.
Cylinder preheating type hot water boiler provided by the invention is compared with prior art and is had the following advantages:
The water inlet of the hot-water boiler of prior art is directly or indirectly at first to enter heat dump heat absorption in the combustion chamber, because inflow temperature is low, influences the burning of fuel; The flue gas that the water that temperature raises has reduced temperature with smoke pipe in the drum again carries out temperature exchange, because both temperature difference are less, is unfavorable for water absorption flue gas heat.The cylinder preheating type hot water boiler water inlet at first enters drum, and the low-temperature flue gas heating water at low temperature with smoke pipe helps the water heat absorption; The water that obtains uniform temperature delivers to that heat dump carries out the high temperature heating in the combustion chamber again, and such mode of heating helps the water heat absorption, and full combustion of fuel has improved the temperature of combustion chamber again.Cylinder preheating type hot water boiler can improve 8 percentage points than existing boiler thermal output.
Description of drawings:
As figure, be the structural representation of cylinder preheating type hot water boiler provided by the present invention.
Among the figure:
Heat dump 3-smoke pipe 4-dividing plate 5-lower drum district in the 1-drum 2-combustion chamber
6-upper drum district 7-upper drum district delivery port 8-upper drum district water inlet
Delivery port 10-combustion chamber, 9-lower drum district heat dump water inlet
The specific embodiment:
When installing and using cylinder preheating type hot water boiler, upper drum district water inlet 8 is connected with user's backwater mouth of pipe, lower drum district delivery port 9 is connected with user's delivery port.
In boiler when work,, water at low temperature is through in the water inlet 8 upper drum districts 6, upper drum district, with the low-temperature flue gas of smoke pipe 3 sufficient heat exchange takes place; The water that temperature raises is entered in the combustion chamber heat dump 2 by upper drum district delivery port 7 and combustion chamber heat dump water inlet 10, carries out the high temperature heating, and the water of rising temperature is arranged to the user through lower drum district delivery port 9 through lower drum district 5.
