Description
Technical field
The present invention relates to a kind of hot-water boiler, particularly a kind of employing is divided into the high cold ambient pressure water boiler that multizone burns.
Background technology
Along with the fast development of economic construction, the people's living standard is steadily improving, and people constantly increase the demand of the energy.The speed of economic development rapid development is the level of utilizing based on the growth rate of the energy and the energy.Formation and reserves for conventional energy resource, be since millions upon millions of years, through very long accumulation and differentiation, just provide real genus the pitiful limited energy of this point point for us, under we several generations' consumption and waste, be about in the not long time, also can become ruins, wherein hot-water boiler mainly is used in North China, northeast and the Northwest, account for more than 93% of total amount, the present boiler of China is a main fuel with the raw coal without washing still, and the boiler major part is traditional structure, and this must cause some problems: mainly show:
(1) low, the coal consumption cauldron of boiler thermal output is main fuel with the coal, evenly heat efficient about 60%, and than low 15-20 percentage point of developed country, cause the low main cause of boiler thermal output: raw coal is low in grate furnace internal combustion efficient; Burning is organized bad; It is improper that furnace heating surface is arranged; Heat-transfer effect is poor; The convection heating surface utilization rate is low, the exhaust gas temperature height; Ature of coal is changeable, not by the design operating fuel.
(2) smoke abatement device imperfection causes most of boiler chimney discharging black smokes, and oke exhaust blackness, dust concentration and S0 concentration of emission seriously surpass national environmental standard.Burn natural gas energy safe operation afterwards for guaranteeing that existing coal-burning boiler changes, must carry out necessary transformation boiler body, combustion system.
Because normal-pressure boiler is suitable for characteristics such as coal is wide, coal consumption is low, be widely used.Be that present coal gas technological process is the simplest, equipment and construction investment is minimum, Operation and Maintenance environmental protection equipment the most simply and easily, be the energy-efficient green product that all kinds boiler of direct combustion coal updates.
And the subject matter that exists at present is, how to improve the abundant burning of coal, and coal is fully burned, and just can improve environment protecting.
Summary of the invention
The objective of the invention is to,, adopt repeated combustion,, make it discharge environmental protection more so that fire coal is fully burned by a kind of high cold ambient pressure water boiler is provided.
The present invention adopts following technological means to realize:
A kind of high cold ambient pressure water boiler includes: body of heater (1), fire door (7), cyclic water jacket (80), flue (90); Be provided with at least four dividing plates in the described body of heater, body of heater is isolated into five combustion zones at least; Its median septum (3) and dividing plate (5) were put the end of for, and the bottom is isolated, and top is open space; Dividing plate (4), dividing plate (6) are overhead, and the top is isolated, and the bottom is an open space; Described combustion zone is respectively: coal-fired district (30), the coal-fired district of bulky grain thing (40), small-sized particle combustion zone (50), smoke combustion district (60), the economizer thermal treatment zone (70).
Aforesaid cyclic water jacket (80) is arranged on both sides in the body of heater, and several water pipes of upside connect in the body of heater by being arranged between both sides cyclic water jacket (80).
Described water pipe can be straight tube, also can be bending.
Aforesaid flue (90) is connected with the exhaust opening of the described economizer thermal treatment zone (70).
Also be provided with safety valve ((8), Pressure gauge (10), thermometer (11) on the aforesaid body of heater (1).
Be respectively equipped with the removing dust and clearing ash door between aforesaid combustion zone (40) and (50) and between combustion zone (60) and (70).
The present invention compared with prior art has following remarkable advantages and beneficial effect:
A kind of high cold ambient pressure water boiler of the present invention, owing to be provided with coal-fired district (30), the coal-fired district of bulky grain thing (40), small-sized particle combustion zone (50), smoke combustion district (60), a plurality of combustion zones, the economizer thermal treatment zone (70), be provided with many places ability of swimming dedusting area, economizer simultaneously, therefore, make coal in body of heater, obtain sufficient burning, the low pollution of discharging, smokeless substantially, reached environmental requirement, exhaust gas temperature 80-100 ℃, because rational in infrastructure, long service life need not be keeped in repair within 5 years.
