Definitions
- the present invention is directed to the recovery of waste heat from chemical reactions. More particularly, the invention relates to a waste heat boiler with improved control of cooling effect.
- Waste heat boilers are most generally used for the generation of steam by waste heat recovered from hot process streams.
- those boilers are designed as shell-and- tube exchangers with a plurality of heat exchanging tubes arranged within a cylindrical shell.
- the characteristic components of the boiler are the tubes mounted in tubesheets at a front-end head and a rear- end head within the shell.
- steam production is accomplished on the shell side of the tubes by indirect heat exchange of a hot process stream flowing through the boiler tubes.
- the shell side is through a number of risers and down-comers connected to a steam drum, which may be arranged above or as an integral part of the boiler shell.
- Boilers handling fouling and/or corrosive process streams must be designed to a higher duty than required when clean in order to allow for satisfying lifetime under serious fouling and/or corroding conditions.
- the heat transferring surface of the boiler tubes has further to be adapted to expected corrosion and fouling factors in the stream. To provide for a desired and substantially constant cooling effect during long term operation of the boilers, appropriate heat transfer and temperature control is required.
- a major drawback of the known boilers of the above type is vigorous corrosion on the metallic surface of the by-pass, particularly the by-pass outlet and flow control valve, which are in contact with the un-cooled process stream at temperatures as high as 1000°C or even higher.
- Known art has sought to solve this problem in various manners such as cooling the control valve with a cooling fluid or to avoid a hot by-pass stream and in stead divide the heat exchanger in different sections with different heat-exchange level and therefore different process gas outlet temperatures. Examples of known art are disclosed in US5452686A, US2007125317A, US4993367A, GB1303092A, US1918966A and EP0357907A.
- An object of this invention is to avoid the drawbacks of the known waste heat boilers by providing a boiler of the shell- and-tube heat exchanger type with an improved heat transfer and temperature control.
- a further object of this invention is to provide a waste heat boiler with a simpler and less expensive design than known art waste heat boilers.
- a further object of this invention is to provide a waste heat boiler with a process gas by-pass tube and a control valve for simple control of the by-pass process gas stream and accordingly the process gas outlet temperature, without exposing the control valve to excessive temperatures leading to corrosion.
- a waste heat boiler for heat exchanging a relatively hot process gas with a cooling media
- the waste heat boiler comprises at least one shell part (a heat ex- change section second shell part) , and at least two tube sheets placed in an inlet end and an outlet end of the heat exchange section second shell part, whereby this second shell part and the two tube sheets enclose the heat exchange section of the waste heat boiler.
- a plurality of heat exchange tubes and at least one process gas by-bass tube are placed in the heat exchange section and are fixed in the first tube sheet near the first end of each tube and fixed in the second tube sheet near the second end of each tube.
- At least one cooling media inlet and at least one cooling media outlet are located on the waste heat boiler to enable a cooling media to flow into and out of the heat exchange section on the shell side of the tubes.
- the cooling media is thus enclosed by the second shell part and the first and the second tube sheet.
- a process gas inlet section is located near the first tube sheet, on the opposite side than the cooling media.
- the inlet section may further be enclosed by a first shell part at the process gas inlet end.
- a process gas outlet section is located near the second tube sheet also on the opposite side of the cooling media. Also the outlet section may further be enclosed by a third shell part.
- an outlet process gas collector is located such that it collects at least a part of the process gas exiting the at least one by-pass tube and also collects the cooled process gas exiting a part of the heat exchange tubes .
- Process gas flows from the first shell part, process gas inlet end, to the heat exchange tube inlets and the by-pass tube inlet, through the heat exchange tubes and the at least one by-pass tube, out of the heat exchange tube outlets and the at least one by-pass process gas outlet to the third shell part, process gas outlet end.
- a cooling media flows into the heat exchange section via the cooling media inlet and is in contact with the shell side of the heat exchange tubes and can be in contact with the shell side of at least one by-pass tube before the cooling media exits the heat ex- change section through the cooling media outlet.
- the process gas enters the process gas inlet section at a first temperature and exits the heat exchange tubes at a second relatively low temperature.
- the process gas exiting the by-pass tube has a third temperature which is lower or equal to the first temperature, but higher than the second temperature.
- the outlet process gas collector mixes at least a part of the by-pass process gas and a part of the heat exchanged process gas.
- the mixed process gas temperature has a fourth temperature which is higher than the second temperature, but lower than the third temperature.
- the amount of heat exchanged process gas and the amount of by-pass gas in this mix is com- posed such that this fourth temperature is low enough to prevent excessive corrosion of the control valve which is located downstream of the collected by-pass and heat-exchanged process gas.
- the control valve controls the amount of mixed process gas in the total process gas stream exiting the waste heat boiler.
- the total process gas stream exiting the waste heat boiler should be of a certain fifth temperature, which is higher than or equal to the second temperature, but lower than the fourth temperature.
- the control valve can control the volume flow of mixed process gas as compared to the total exiting process gas volume flow and thus control the fifth temperature even with varying second and fourth temperatures and volume flows.
- the fifth temperature can be kept constant by use of the control valve to decrease the volume flow of the by-pass process gas having a fourth temperature.
- the mix- ing of the heat exchanged process gas and the by-passed process gas in the outlet process gas collector can be enhanced by mixing means located in the collector up-stream of the control valve.
- the mixing means can be of any known function and materials.
- the collector collects the process gas exiting the one by-bass tube and the heat-exchanged process gas exiting at least one of the heat exchange tubes.
- the process gas inlet section is lined with a ceramic liner for protecting the first shell part from the relative hot process gas.
- the mixing means and the process gas collector can be lined with a ceramic liner.
- the cooling media can be water or it can be steam.
- the cooling media can be water when entering the heat exchange section and a part of the water or all of the water can be heated by the indirect heat-exchange with the relative hot process gas such that all or a part of the cooling media exiting the heat exchange section via the cooling media outlet is steam.
- the second shell part or both the first, the second and the third shell part can be substantially cylindrical.
- the cylindrical shape can be advantageous as it is a pressure robust and material saving shape. By substantial is meant any shape which is oblong in one cross sectional view and any shape. which is not far from circular in another cross sectional view, such as circular, elliptic, square, pentagonal, hexagonal etc.
- a plurality of heat exchange tubes are placed in a substantially circular array in the tube sheets and the by-pass tube or the at least one by-pass tube is placed substantially in the center of the array.
- substantially meant, that the location does not have to be mathematically accurate, the shapes can vary to a large extent as long as consideration to heat-exchange effectiveness and material costs are respected.
- the waste heat boiler is used in a process plant producing wet sulphuric acid.
- Waste heat boiler for heat exchanging a relatively hot process gas with a cooling media comprising
- the relatively hot process gas enters the heat exchange tubes and the at least one by-pass tube in the process gas inlet section, flows through the heat exchange section where at least the process gas flowing in the heat exchange tubes is in indirect heat exchange with the cooling media and exits in the process gas outlet section, wherein said waste heat boiler further comprises a control valve and an outlet process gas collector, said control valve is enabled to control the volume stream of the process gas which flows through said outlet process gas collector, the process gas collector collects at least a part of the process gas exiting the at least one by-pass tube and the cooled process gas exiting a part of the heat exchange tubes.
- outlet process gas collector further comprises mixing means located up-stream of the control valve, for mixing the relatively hot process gas exiting the at least one by-pass tube with the cooled process gas exiting a part of the heat exchange tubes.
- Waste heat boiler according to any of the preceding features comprising one by-pass tube, wherein the outlet process gas collector collects the process gas exiting the bypass tube gas and the exiting process gas of at least one of the heat exchange tubes.
- Waste heat boiler according to any of the preceding fea- tures, wherein the process gas inlet section is lined with a ceramic liner.
- Waste heat boiler according to feature 4 wherein further the inside wall of the bypass tube is lined and at least part of the outlet process gas collector is lined with a ceramic liner. 6. Waste heat boiler according to any of the preceding features, wherein the cooling media is water or steam or both water and steam.
- Waste heat boiler according to any of the preceding features, wherein said shell has a substantially cylindrical shape and said at least two tube sheets have a substantially circular shape.
- the waste heat boiler comprises a first shell part, process gas inlet end 110; a second shell part, heat exchange section 120 and a third shell part, process gas outlet end 130; all having a substantially cylindrical shape and substantially the same diameter, but as can be seen on the figure, not necessarily the same material thickness.
- the material thickness as well as the choice of material can be varied depending on the process conditions.
- a first tube sheet, process gas inlet end 115 separates the first shell part from the second shell part.
- a second tube sheet, process gas outlet end 125 separates the sec- ond shell part from the third shell part.
- the internal surface of the process gas inlet section can have a liner 111, for instance a ceramic liner to protect the internal surfaces from the high temperatures of the inlet process gas.
- the first and the second tube sheets have corresponding bores to accommodate heat exchange tubes 123.
- the heat exchange tubes stretch at least from the first tube sheet through the heat exchange section and at least to the second tube sheet.
- the connection between each heat exchange tube and each of the tube sheets are made gas and liquid tight.
- Each heat exchange tube has a heat exchange tube inlet 114 located in the process gas inlet section and a heat exchange tube outlet 134 located in the process gas outlet section.
- the first and the second tube sheets also have at least one corresponding bore for at least one process gas by-pass tube 124.
- the connection between the process gas by-pass tube and the first and the second tube sheet is made gas and liquid tight.
- the process gas by- pass tube has a by-pass process gas inlet 113 located in the process gas inlet section and a by-pass process gas outlet 133 located in the process gas outlet.
- the process gas bypass tube can be provided with a lining (not shown) which can protect the tube from the relative high process gas tempera- tures and which may also reduce the indirect heat exchange between the cooling media and the by-passed process gas.
- a cooling media inlet 121 provides fluid connection of a cooling media to the heat ex- change section.
- the at least one cooling media inlet can be located in any position on the second shell part or even on the first or the second tube sheet, as long as fluid connection to the heat exchange section is provided.
- a location on the shell part of the heat exchange section is shown on fig. 1.
- a cooling media outlet 122 located in fluid connection to the heat exchange section provides outlet of the cooling media from the heat exchange section.
- Each of the heat exchange tubes and the process gas by-pass tube thus provides fluid connection from the process gas inlet section through the heat exchange section and to the process gas outlet section, thereby enabling the process gas to flow through the heat exchange section without direct contact to the cooling media.
- the process gas flowing in the heat exchange tubes is in indirect heat-exchange with the cooling media, whereas the part of the process gas which is by-passed, i.e.
- the process gas by-pass tube is in less or relative low or substantially no indirect heat- exchange with the cooling media: If the by-pass tube is not lined, the by-passed process gas will have some heat-exchange with the cooling media, but the heat-exchange in the by-pass tube will be relative lower than the heat-exchange in the heat exchange tubes due to the by-pass tube's higher volume to surface ratio. If the by-pass tube is lined, for instance with a ceramic liner, the indirect heat-exchange between the by-passed process gas flowing in the by-pass tube and the cooling media will be relative low or close to zero. In any case, the temperature of the heat-exchanged process gas exiting the heat exchange tube outlets is considerably lower than the temperature of the by-passed process gas exiting the bypass process gas outlet.
- an outlet process gas collector 136 is located in the process gas outlet section. It collects the by-passed process gas and a part of the heat-exchanged process gas.
- the process gas collector collects the by-passed process gas and the heat-exchanged process gas exiting the heat-exchange tubes located nearest to the bypass tube in a circular array around the by-pass tube.
- Outlet process gas mixing means are located inside the process gas collector ensuring mixing of the by-passed and the part of the heat-exchanged process gas to an extent so the control valve, by-pass tube outlet 135 is not exposed to a critical amount of process gas with a temperature so high it will lead to substantial corrosion of the control valve.
- Said control valve controls the amount of mixed process gas which is exited from the outlet process gas collector to the process gas outlet section.
- the control valve can vary the temperature of the process gas exiting the process gas outlet section within an interval between the temperature of the heat-exchanged gas and the mixed by-pass gas. Or more important, the control valve can keep the temperature of the process gas exiting the process gas outlet section on a certain level, even though the temperature of the heat-exchanged process gas vary due to for instance reduced indirect heat-exchange because of for instance fouling in the heat-exchange tubes.
- Fig. 2 shows the waste heat boiler of fig. 1 with the temperatures noted. The temperatures have the following relations :
