Abstract
The utility model discloses a fuel and gas organic heat-carrier boiler which comprises a fuel and gas burner, a top cover, a burner interface, a heating surface of a boiler body, a barrel body, a heat insulating layer and a base, wherein the burner interface is arranged on the middle part of the top cover and connected with the top cover by a bolt, and the burner interface is provided with a viewing mirror. The fuel and gas burner is arranged on the top cover through the burner interface and connected with the burner interface through a bolt. The heating surface of the boiler body is composed of two layers of inner coil pipes and outer coil pipes or three layers of inner coil pipes, middle coil pipes and outer coil pipes. Two layers of heat-resistant stainless steel annular sealing sleeve rings are welded on the inner coil pipes of the heating surface of the boiler body, and the lower side of the top cover is welded with a circular heat-resistant stainless steel sealing plate and a pressing plate. The utility model has the advantages of novel design and simple idea. The utility model solves the technical problems that the top cover of the boiler and the coil pipes in the heating surface of the boiler body have poor sealing performance, easy formation of fume short circuit, barrel body burnout, etc. The utility model is a quite ideal fuel and gas organic heat-carrier boiler.
Description
Technical field the utility model belongs to the boiler technology field, is specifically related to a kind of fuel-firing gas-firing boiler of organic heat carrier.
Background technology is along with fast development of market economy, a lot of industries are increasing to the demand of boiler, because boiler of organic heat carrier has low-voltage high-temperature, can realize the adjusting of stable heating and precise dose, advantages such as heat energy, heat loss are little are carried in closed cycle, liquid phase, have obtained swift and violent development in recent years.Boiler of organic heat carrier is still based on coal-burning boiler at present, and the coal-burning boiler existence is burnt, the thermal efficiency is low, and environmental protection index is difficult to reach problems such as class area environmental requirement.Along with the pay attention to day by day of country to environmental protection, a lot of flourishing coastal cities and medium-sized city propose, and do not allow to use the coal burning organic heating medium boiler, allow to use the fuel-firing gas-firing boiler of organic heat carrier.At present, the fuel-firing gas-firing boiler of organic heat carrier of China is owing to be subjected to the structural limitations of boiler of organic heat carrier, exists between top cover and the boiler body heating surface inner coil pipe sealing bad, easily causes the flue gas short circuit, burns out problems such as cylindrical shell.
The summary of the invention the purpose of this utility model provides the fuel-firing gas-firing boiler of organic heat carrier of good seal performance between a kind of boiler top cover and the boiler body heating surface inner coil pipe, to remedy the deficiencies in the prior art.
The utility model is to improve realization on the basis of existing technology, is the circular discs tubular construction, can vertically place, and also can horizontally place; It comprises fuel-firing gas-firing burner, top cover, burner interface, boiler body heating surface, cylindrical shell and heat-insulation layer and base, and the burner interface is located at the top cover middle part, connects by bolt and top cover, which is provided with visor; The fuel-firing gas-firing burner is arranged on the top cover by the burner interface, connects with the burner interface by bolt; Said boiler body heating surface by in two-layer inside and outside coil pipe or three layers, domestic and abroad coil pipe forms; Its main points are to be welded with two-layer heat-resistance stainless steel ring packing lasso on the boiler body heating surface inner coil pipe, are welded with circular heat-resistance stainless steel sealing plate and pressing plate below the top cover.
In order further to improve the sealing property between top cover and the boiler body heating surface inner coil pipe, prevent to cause the flue gas short circuit, burn out sealing plate and cylindrical shell, and guarantee that boiler body can free wxpansion after being heated, adopt socket fitting type structure between sealing plate below the top cover and pressing plate and the inner coil pipe, the resistant to elevated temperatures aluminosilicate fiber cotton of ring packing lasso chock off, driving two-layer ring packing lasso behind the boiler body expanded by heating moves up, because being connected as a single entity, sealing plate and pressing plate and top cover keep motionless, aluminosilicate fiber cotton is further compressed, thereby guaranteed the sealing at this place.
In order to increase the service life of fuel-firing gas-firing burner, the length that the fuel-firing gas-firing burner stretches in the burner hearth is shorter than burner interface, makes the fuel-firing gas-firing burner significantly reduced by radiation of burner hearth heat.
In order to prevent that sealing plate and ring packing lasso from being burnt out, be lined with a circle refractory brick or a refractory concrete in the burner interface, the burner interface stretches into the thickness that the interior length of burner hearth surpasses sealing plate and ring packing lasso, can shelter from sealing plate and ring packing lasso like this, make sealing plate and sealing ring significantly reduced by radiation of burner hearth heat.
Convenient for the dismounting maintenance, top cover and burner interface and cylindrical shell all adopt Bolt Connection.
Operation principle of the present utility model is: fuel such as light oil or natural gas burn through the fuel-firing gas-firing burner, the chemical energy of fuel is converted to heat energy, become high-temperature flue gas, organic heat carrier is circulating in the coil pipe of boiler body heating surface, absorb the radiant heat of high-temperature flue gas earlier by the inner coil pipe tube wall, after being entered the convection heating surface district that reaches between the inside and outside coil pipe between cylindrical shell and the outer coil pipe by the high-temperature flue gas after the radiation heating-surface heat absorption, its heat continues to be absorbed by organic heat carrier in the coil pipe.High-temperature flue gas has become low-temperature flue gas after the heating surface heat absorption of radiation area and convective region, discharged out of the furnace through chimney row to atmosphere by outlet flue.
The utility model modern design, design tube are single, solved between boiler top cover and the boiler body heating surface inner coil pipe sealing bad, easily cause the flue gas short circuit, burn out technical problem such as cylindrical shell, be a kind of more satisfactory fuel-firing gas-firing boiler of organic heat carrier.
