Abstract
The utility model provides a high temperature and high pressure boiler. A high temperature and high pressure temperature-decreased pressure reducer is arranged on one side of a steam supply pipeline of the high temperature and high pressure boiler. The high temperature and high pressure temperature-decreased pressure reducer is arranged on the high temperature and high pressure boiler, when a back pressure unit fails or halts, high temperature and high pressure steam passes through the high temperature and high pressure temperature-decreased pressure reducer, and is reduced into medium-temperature and medium-pressure steam to drive a downstream blast furnace steam dragging fan for using steam, therefore, blast furnace production is ensured.
Description
Technical field
The utility model belongs to Boiler Steam decrease temperature and pressure field, relates to a kind of high-temperature high-pressure boiler.
Background technology
Conventional high-temperature high-pressure boiler steam reduces to medium temperature and medium pressure steam through the back pressure unit with high temperature and high pressure steam, removes to drive downstream blast furnace vapour and drags blower fan vapour.If back pressure unit fault or when shutting down, blast furnace vapour drag the blower fan must the underproduction or blowing out, can not guarantee blast furnace production, caused loss.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art; a kind of high-temperature high-pressure boiler is provided; this boiler comes on the feed channel and has connect the HTHP temperature-decreased pressure reducer existing high-temperature high-pressure boiler; when back pressure unit fault or shutdown; make high temperature and high pressure steam pass through the HTHP temperature-decreased pressure reducer; high temperature and high pressure steam is reduced to medium temperature and medium pressure steam, remove to drive downstream blast furnace vapour and drag blower fan vapour, thereby guarantee blast furnace production.
The purpose of this utility model solves by the following technical programs:
A kind of high-temperature high-pressure boiler comes steam pipe road one side that the HTHP temperature-decreased pressure reducer is installed at high-temperature high-pressure boiler.
Above-mentioned high-temperature high-pressure boiler come to be provided with at least one group of back pressure machine on the feed channel the large porthole of the row of being disposed with and steam discharge door on the blow-off line of back pressure machine.
Be provided with pressure-reducing valve and desuperheat valve on the above-mentioned HTHP temperature-decreased pressure reducer.
It is direct current 24V that above-mentioned pressure-reducing valve and desuperheat valve adopt operating voltage.The work bleed pressure remains on the pneumatic operated valve between the 0.45-0.6MPA.
Above-mentioned high-temperature high-pressure boiler come to be provided with two HTHP temperature-decreased pressure reducers on the steam pipe road.
The utility model is by installing the HTHP temperature-decreased pressure reducer at high-temperature high-pressure boiler; when back pressure unit fault or shutdown; make high temperature and high pressure steam pass through the HTHP temperature-decreased pressure reducer; high temperature and high pressure steam is reduced to medium temperature and medium pressure steam; remove to drive downstream blast furnace vapour and drag blower fan vapour, thereby guarantee blast furnace production.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Wherein: 1 is the HTHP temperature-decreased pressure reducer; 2 is back pressure machine; 3 is the steam discharge door; 4 are the large porthole of row.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1, this high-temperature high-pressure boiler comes steam pipe road one side that HTHP temperature-decreased pressure reducer 1 is installed at high-temperature high-pressure boiler.High-temperature high-pressure boiler come to be provided with at least one group of back pressure machine 2 on the feed channel the large porthole 4 of the row of being disposed with and steam discharge door 3 on the blow-off line of back pressure machine 2.Be provided with pressure-reducing valve and desuperheat valve on the HTHP temperature-decreased pressure reducer 1.It is direct current 24V that pressure-reducing valve and desuperheat valve adopt operating voltage.The work bleed pressure remains on the pneumatic operated valve between the 0.45-0.6MPA.High-temperature high-pressure boiler come to be provided with two HTHP temperature-decreased pressure reducers 1 on the steam pipe road.
Referring to Fig. 1, the course of work of the present utility model is achieved in that
At high-temperature high-pressure boiler the HTHP temperature-decreased pressure reducer is being installed; when back pressure unit fault or shutdown; the back pressure unit steam flow amount of advancing is passed through temperature-decreased pressure reducer within 3 seconds; high temperature and high pressure steam is reduced to medium temperature and medium pressure steam; be transported to downstream blast furnace vapour and drag blower fan; drive the work of blast furnace vapour holder blower fan, thereby guarantee blast furnace production.
The utility model optimal case adopts two HTHP temperature-decreased pressure reducers, a continuous firing, and another is as unit for subsequent use.By adopting tracing and fault method, within 3 seconds, make the back pressure unit steam flow amount of advancing reach the required steam flow of downstream user, temperature and pressure by temperature-decreased pressure reducer, reduced unnecessary production loss.
