overcritical W flame boiler; Its composition comprises: the furnace arch, furnace nose district buckstay that is connected with water-cooling wall; Described water-cooling wall front side connects the face arch erecting by overhang; Described water-cooling wall rear side connects the rear arch erecting by overhang; Described face arch erecting by overhang comprises the face arch tube panel that is connected with described water-cooling wall; Described face arch tube panel connects the L template; Described face arch tube panel connects load-bearing otic placode T template; Described T template connects the bottom truss by suspension rod; Described load-bearing otic placode connects main suspension rod by U type folder, and described main suspension rod connects the preceding suspension and support that has spring hanger.
The front and back arch erecting by overhang of
described overcritical W flame boiler; Described rear arch erecting by overhang comprises bottom, back truss; Truss bottom, bottom, described back connects suspension rod down; Described suspension rod down connects back U type folder; Truss top, bottom, described back connects upper hanger; Described upper hanger connects the back suspension and support, and described back suspension and support connects the rear spring suspension bracket.
A kind of manufacturing approach of front and back arch erecting by overhang of overcritical W flame boiler; This hangar system is divided into two major parts, and the truss hanging structure double as that the bottom is used to hang front and back arch tube screen and increase the tube panel rigidity is that the truss and the top of hot bellows is used to suspend in midair the hanging structure that hangs the bottom truss;
Truss inboard, bottom is fixed on the front or rear water water-cooling wall of boiler; Conduction portion load is born by forward and backward water-cooling wall; Downside is through U type folder; T template, L template, load-bearing otic placode, be connected before and after on the arch tube screen, the outside is suspended by suspension rod then in midair to prop up hanging beam to the boiler top be to be the rear arch erecting by overhang on face arch erecting by overhang or the furnace arch, furnace nose district buckstay;
top is used to suspend in midair the hanging structure that hangs the bottom truss, is composed in parallel by suspension rod and constant force disc spring hanger; Through the various annex load on arch tube screen and the tube panel before and after the suspention of bottom truss structure; The downward thermal walking of arch tube screen before and after discharging.
Beneficial effect:
A compound suspending way that overlaps brand-new form has been adopted in
1. the present invention; Both solved the deficiency that conventional in the past suspending way rigidity is big, load is uneven; Strengthened the rigidity of overcritical W flame boiler front and back arch again; Be the special research and development of first the overcritical W flame boiler in the exploitation world; Have good security and market potential, be domestic initiation, product advanced in the world.
2. the invention solves before and after the overcritical W flame boiler in first of the world arch tube screen and hang that difficulty is big, load is uneven, and the difficult problem of tube panel poor rigidity can satisfy the requirement of arch suspention before and after the overcritical W flame boiler.
3. the present invention can strengthen overcritical W flame boiler front and back arch tubes screen rigidity, satisfy the requirement that tube panel thermal expansion displacement is big, load is uneven.
4. the present invention are divided into two major parts, and the truss hanging structure (double as is the truss of hot bellows) and the top of arch tube screen and increase tube panel rigidity were used to suspend in midair the hanging structure that hangs the bottom truss before and after the bottom was used to hang.
Before and after
truss structure 5. of the present invention can discharge arch tube screen about, the thermal expansion of former and later two directions, prevent tube panel because thermal expansion destroys; The rigidity of arch tube screen before and after this truss structure can increase, the transient load that reasons such as quick-fried owing to boiler furnace in the arch tube screen before and after bearing, urgent blowing out produce prevents that tube panel is destroyed; The intrinsic frequency of arch tube screen made tube panel not produce resonance before and after this truss structure can change, and the arch tube screen produces destruction because of resonance before and after preventing; This truss structure can be used as the truss structure of hot bellows, has simplified boiler structure.
Description of drawings:
accompanying drawing 1 is mounted in the face arch erecting by overhang structural representation of this product on the water-cooling wall.
accompanying drawing 2 is mounted in the rear arch erecting by overhang structural representation of this product on the water-cooling wall.
