Abstract
The utility model discloses an automatic coal gasification control energy saving boiler comprising a boiler body and a combustion chamber, wherein the combustion chamber is provided with a coal bin, a slag discharge port and an air inlet; the combustion chamber is internally provided with an inclined air inlet coal retaining grate bar below a coal port of the coal bin; the inclined air inlet coal retaining grate bar is formed by the arrangement of a plurality of metal rods or metal tubes and forms an inclined surface with an inclined angle being 40-45 degrees with the horizontal surface; and each of the metal rods or the metal tubes is provided with an air retaining sheet. The automatic coal gasification control energy saving boiler can perform smokeless, and dustless combustion during use, combines the common characteristics of a back fire furnace and a reverberatory furnace, changes coal combustion into gas combustion, thereby improving the combustion valve; the operation of the boiler is convenient as coal is supplied freely and slag falls free after burning out.
Description
Technical field
The utility model relates to a kind of coal-fired hot-water boiler.
Background technology
At present, the hot-water boiler that uses on the market, based on straight burning and back firing boiler, their coal consumptions are big, and flue dust is many, and is seriously polluted, and the thermal efficiency is low, and needing to be equipped with dust-removal and desulfurizing equipment can use.Because coal gasification boiler is wide in variety, the coal gasification boiler that has in the process of promoting the use of is comparatively strict to the requirement of fuel, can only use lump coal, raw coal comparatively in small, broken bits can't use, the coal gasification boiler that has need be equipped with complicated auxiliary device, increase manufacturing cost and operating cost, be unfavorable for the popularization and the extensive use in market.The patent No. is that 200620029307.5 Chinese patent discloses a kind of staged fire bars and can realize the loose burning in coal seam, but can not realize not having the cigarette ash burning.
Summary of the invention
The utility model provides a kind of coal gasification auto-control energy-saving boiler in order to remedy the deficiencies in the prior art, and this kind boiler structure is simple, and is compact to design, easy to use, energy-conserving and environment-protective.
The utility model is achieved by the following technical solution:
Coal gasification auto-control energy-saving boiler, comprise body of heater, combustion chamber, on the combustion chamber, be provided with coal bunker, slag notch, air inlet, be provided with inclined air intake retaining coal stove bar below the inherent coal bunker coal feed point in combustion chamber, inclined air intake retaining coal stove bar is arranged by many metal bars or metal tube and is formed, be arranged in horizontal by the inclined-plane of 40 ° of-45 ° of angles, metal bar or metal tube are provided with blinker.
Being provided with first backhaul of three backhaul fireworks channels in the described body of heater is the boiler wall interlayer, and the 3rd backhaul is the steel pipe of central core, and second backhaul is the steel pipe between boiler wall interlayer and the central core.
Described body of heater is provided with temperature sensor and links to each other with the computer temperature control system.
Fire bars structure welding blinker, the oxygen air will flow to side-lower, combustion-supporting coal seam to enter indoor the containing of boiler combustion.Make the flare operation downwards earlier after the burning, run parallel again, discharge body of heater along first, second and third backhaul passage upward at last.
The beneficial effects of the utility model are:
Owing to adopt inclined air intake retaining coal stove bar, behind the coal bunker coal, coal is evenly spread the coal seam of 20 centimetres of one decks along fire bars 5, light back coal seam oxidation, reduction, destructive distillation, dry, coking, behind the after-flame ashes, cinder drops to the bottom, and the coal of coal bunker replenishes the vacancy circulating combustion that the coal seam burns automatically, the producer gas process of this similar gas generator in combustion system fire bars top, middle part and bottom are the carry out mode of side air intake in conjunction with flow-down burning, whole process smokeless and dust free burns, and has had the common feature of anti-burning stove and reverberatory furnace concurrently, becomes the coal-fired combustion gas that is, improved the combustion value, the free-falling of slag after-flame, coal-fired effect of freely replenishing makes boiler attendance more convenient.Install simultaneously and can realize that temperature controls voluntarily behind the computer temperature control device, the overtemperature alarm function reduces boiler bar thermal discharge, better realizes purpose of energy saving.
