Description
Affiliated technical field
The present invention relates to a kind of high temperature automatic forced-circulation boiler.It can be at no pump, do not have to press (normal pressure) or have under the pressure condition, and the leaving water temperature height, the radiator temperature is high and can make water in the whole heating system make the hot-water boiler of automatic forced circulation.
Background technology
At present, the hot-water boiler in usefulness all exists both at home and abroad: leaving water temperature is low, circulation rate is slow, the radiator temperature is low or with water pump pressure cost height, big, the use inconvenience of investment are arranged, and is easy to generate drawbacks such as mechanical breakdown or power failure cause the accident.As everyone knows, boiler is to utilize each several part water temperature in the system different and the temperature difference (being gravitational difference) that forms and the difference in height of stove center line and radiator center line realize circulating under atmospheric pressure state.Though natural cycle system is simple, operation is convenient, not being subjected to have a power failure influences, and also mechanical accident can not occur, still: " it is also hiding huge waste; the radiator upper and lower temperature difference is bigger under the situation of Natural Circulation, can be up to 40-60 ℃, and hot or not down phenomenon is commonplace in the formation.This is in low-temperature condition with regard to the radiating surface that makes considerable part, be difficult to play a role, have at least 1/4th heat not bring into play, this is a huge waste ... therefore, solve the circulatory problems of Household water heating boiler (coal stove) circulatory system, the running quality that improves heating installation to economizing on resources is significant " (the content system in the above quotation marks draw the 1st edition 170 pages of " the practical energy-saving cooking " published from Chemical Industry Press October in 2004 with 171 pages).Also doing a large amount of research aspect the raising thermal efficiency abroad.For example: under the configuration that pressure and water pump are arranged, adopt submerged combustion, intermittent combustion and condenser boiler, as " the MAXIMAGAS integrated condensation gas boiler structure that UItragas that Switzerland's Hoval (Hoval) company produces and the graceful Robbie of Britain's prestige (WeIImanRobey) company produce " (the content system in the quotation marks draw the 1st edition 90 pages of " the middle-size and small-size fuel oil combustion boiler furnace operation and the maintenance " of publishing March in 2003 with 91 pages) from China Machine Press.The burner that also has some foreign corporations to produce is inverted boiler etc.They all are with the burner upside down, the method heat exchange of following water inlet, upper water-out, down smoke-discharging.These structures have played good effect to a certain extent.But bigger waste and trouble are being arranged all aspect materials, structure, the use, for example: have pressure boiler to need thicker steel plate, water pump being arranged or be inverted burner needs complicated structure and increase cost, also can bring inconvenience in use, has a power failure and the water pump fault can cause the accident etc.So just bring certain obstacle for popularizing to use.In order to overcome these shortcomings, the domestic boiler that energy forced circulation under no pump state occurred can also have certain deficiency on structure and effect, and the power that has is faint; The structure that has is too complicated; What also have can not use the heat that discharges in its boiler fully.
For example: in the China Patent No. 85201185 " a kind of forced circulation plumbing fixture of home furnace ", be the forced circulation power source that is cooking stove with a tiny tubulation in the heat exchanging pipe, " produce interrupted injection power " (this patent specification language) to the water outlet direction during operation.China Patent No.: 95119318.X " heated driving unit " is that the U font that is provided with in the furnace chimney or the steel pipe of δ font are heat dynamic resource, " back and forth produces motive force " (this patent specification language) to the water outlet direction during operation.
And for example: China Patent No.: 92240510.7 " no pump automatic circulating hot water heating boilers " are above preheating, water outlet down, and middle finishing with frame for movement changed water or moisturizing, and depended on pressure steam makes the method for system water circulation; This patent is at the thermal efficiency, and there is certain progress water circulation aspect, and shortcoming is a complex structure, and cost is too high.
For another example: China Patent No.: 99114150.4 " a kind of new methods of hot water circuit " is characterized in that: be provided with down-comer in the heat absorption upper of furnace body and communicate with the tedge of body of heater inside, supply with radiator heating behind the tedge process body of heater outer heat-exchanger, as " heat exchanger (5) is installed between heat absorption body of heater (1) and the radiator (2); make the body of heater outlet pipe (4) and the water outlet of radiator outlet pipe (7) carry out heat exchange in 1: 1 therein; thus improved the temperature of water inlet in the body of heater water inlet pipe (3); reduced the temperature of the water inlet in the radiator inleting pipe (6); the turnover temperature difference of heat absorption and heat release reduces synchronously like this; reach and absorb heat and the synchronous increase of heat release flow, increased the interior flow of heating system " (in the quotation marks patent specification second page) for this reason.China Patent No.: 91205520.0 " Pumpless forced circulation boiler for hot-water heating " this patent is to form one with direct heating clamber and indirect chamber two parts, following water inlet, upper water-out structure, with water inlet pipe the check check valve is housed all between two Room, water temperature by direct heating clamber during operation raises, water and steam are entered the indirect chamber through check valve, to system's water supply of exerting pressure.More than two patents all ignored thermal efficiency problem in design, do not utilize well and vow the heat of putting in the boiler.
