Abstract
The utility model discloses a stainless steel boiler, belonging to the boiler field; the technical problem to be solved is to provide a stainless steel boiler which has simple structure, can recover heat and reduce production cost; the technical scheme for solving the technical problem is as follows: a stainless steel boiler is characterized in that: the furnace comprises a furnace body, wherein an air inlet channel is arranged at the upper part of the furnace body, a flue gas box is arranged at the lower part of the furnace body, the furnace body is a square cylindrical barrel, a full premix burner, a round tube bundle and a finned tube bundle are sequentially arranged in the furnace body from top to bottom, a water-cooled wall is arranged on the outer surface of the furnace body, and an inlet of the round tube bundle is connected with an outlet of the finned tube bundle; the utility model discloses but wide application in boiler field.
Description
Technical Field
The utility model relates to a stainless steel boiler belongs to boiler technical field.
Background
Common filtration in the market now, fuel burn the back in the stove courage, and the flue gas passes through the smoke box and arranges the people in the atmosphere, and water gets into the drum from pot shell upper portion or lower part, is full of around stove courage and tobacco pipe, so filter each part temperature difference of temperature not big, but the play water temperature of boiler is higher, has a large amount of heats to discharge, and this part waste of heat is serious, has increased safe risk, has improved manufacturing cost.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes the defects of the prior art, and provides a stainless steel boiler which has simple structure, can recover heat and reduce the production cost.
In order to solve the technical problem, the utility model discloses a technical scheme be: a stainless steel boiler is characterized in that: the furnace body is a square cylindrical barrel, a full premix burner, a round tube bundle and a finned tube bundle are sequentially arranged inside the furnace body from top to bottom, a water-cooled wall is arranged on the outer surface of the furnace body, and an inlet of the round tube bundle is connected with an outlet of the finned tube bundle.
The outer surface of the furnace body is provided with a water inlet pipe seat and a water outlet pipe seat, the water inlet pipe seat is connected with the inlet of the finned tube bundle, and the water outlet pipe seat is connected with the outlet of the round tube bundle.
The furnace body is made of 316L stainless steel.
Compared with the prior art, the utility model following beneficial effect has: the furnace shaft is made of stainless steel, corrosion-resistant and long in service life, the round tube bundle and the finned tubes are used for countercurrent heat exchange, the low-temperature medium is used for absorbing heat in low-temperature flue gas, the high-temperature medium is used for absorbing heat in high-temperature flue gas, heat exchange efficiency is high, heat can be effectively recovered, and sufficient combustion is guaranteed.
Drawings
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a right side view of fig. 1.
In the figure, 1 is a furnace body, 2 is an air inlet channel, 3 is a flue gas box, 4 is a full premix burner, 5 is a round tube bundle, 6 is a finned tube bundle, 7 is a water wall, 8 is a water inlet tube seat, and 9 is a water outlet tube seat.
Detailed Description
As shown in fig. 1 and 2, the utility model relates to a stainless steel boiler, including furnace shaft 1, 1 upper portion of furnace shaft sets up intake duct 2, and the lower part sets up flue gas case 3, and furnace shaft 1 is the square column shape barrel, and furnace shaft 1 is inside from last to having set gradually full premix combustor 4, pipe tube bank 5, finned tube bank 6 down, and 1 surface of furnace shaft is provided with water- cooling wall 7, and 5 imports of pipe tube bank and 6 exports continuously with the finned tube bank, and 1 surface of furnace shaft is provided with inlet tube seat 8 and outlet tube seat 9, inlet tube seat 8 and 6 imports of finned tube bank link to each other, outlet tube seat 9 and 5 exports continuously with pipe tube bank, furnace shaft 1 material is the 316L stainless steel.
The utility model discloses when using, gas and air mixture burn in getting into the full premix combustor through the intake duct, produce the high temperature flue gas, then after the high temperature flue gas loops through pipe tube bank and finned tube bank, become the low temperature flue gas and discharge, use water inlet tube seat and water outlet tube seat to let in recirculated cooling water for pipe tube bank and finned tube bank when the high temperature flue gas gets into the furnace body, carry out the heat transfer to the flue gas, use the water-cooling wall to absorb remaining heat simultaneously, adopt this kind of countercurrent flow's principle, the heat in the low temperature flue gas is absorbed to the low temperature medium, the medium in the high temperature flue gas is absorbed to the high temperature medium, heat exchange efficiency is high, use the finned tube to reduce area simultaneously, reduce the boiler size, use stainless steel, it is corrosion-resistant.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
