Embodiment Construction

[0019] figure 1 It is a side sectional schematic diagram of a traditional dry-back two-pass shell boiler. Refer to the following figure 1 The steam production process of a conventional boiler is explained.

[0020] figure 1 It is a schematic diagram of the side section of a traditional dry-back two-pass shell boiler. In the figure, 100: combustion chamber, 101: front smoke box, 102: smoke box, 103: burner interface, 104: furnace, 105: corrugated furnace, 106: convection tube bundle.

[0021] The following is the steam making process in a traditional boiler. The burner connected to the burner interface 103 ignites the gas or oil and burns it in the furnace 104. In order to prevent the furnace from expanding due to heat, it is generally designed as a corrugated furnace 105 that can relieve thermal expansion. The burned flue gas passes through the combustion chamber 100 enters the convection tube bundle 106, and through the flue gas flowing back and forth, the water in the b...

Abstract

The invention provides a superheated steam combined boiler and a superheated steam making method. The superheated steam combined boiler comprises a combustor arranged in front of a hearth, an inner furnace for combusting fuel in the hearth, a boiler shell, a flow pipe bundle arranged on the hearth, and a reversal chamber located at the tail end of the flow pipe bundle and the hearth. The built-in heat exchanger type superheated steam boiler shell combined boiler comprises at least two boiler bodies which include the frequently-used boiler body and the standby boiler body, wherein a heat exchanger is arranged in the standby boiler body, and the steam outlet of the frequently-used boiler body is connected with the heat exchanger of the standby boiler body. By means of the superheated steam combined boiler and the superheated steam making method, the rising speed of the water temperature in a water pipe can be increased, the time from saturated steam generation to superheated steam generation is shortened, the energy waste caused by different volumes of steam consumption of different time periods is eliminated, the failure rate of devices in the boiler is decreased, the normal production is ensured, the energy consumption is lowered, and the service life of the boiler is prolonged.

Description

technical field [0001] The invention relates to a combined superheated steam boiler and a method for producing superheated steam, in particular to a combined superheated steam boiler and a method for producing superheated steam, belonging to the field of boilers. Background technique [0002] For a long time, boilers as heating equipment mainly use coal energy for heating. Because coal-fired boilers will produce a large amount of flue gas, which will pollute the air, at the same time, the burned slag is also a kind of environmental pollutants. [0003] In recent years, my country has discovered and exploited a large amount of natural gas, and established a large-scale west-to-east gas transmission project. At the same time, it has introduced foreign natural gas and fuel pipelines, providing relatively rich oil and gas resources. [0004] With the improvement of environmental protection awareness and the continuous progress of science and technology, oil and gas fuels are ea...
