Abstract

The invention discloses an efficient energy-saving combustion boiler technique. Most existing thermal power plants use pulverized coal for blasting of boilers, and great improvement is made compared with coal briquette combustion; however, part of unburnt residues still exist in the combustion process of the pulverized coal and flutter to the sky, so that the atmosphere is polluted. In order to achieve the best state of pulverized coal combustion preferably, reduce pollution, reduce the cost, save energy and increase the benefits, the design scheme is formed according to the oxygen jet steel making theory, the oxygen blowing combustion-supporting technique is utilized, the hearth temperature is increased, the gas production rate is increased, and the residues are burnt; in this way, coal can be saved by 15%-25% based on the original coal consumption. If the method is adopted by all the coal thermal power plants and departments using boilers in China, the coal-saving amount will be immeasurable.

Description

Energy-efficient burning boiler technology

Technical field:

The technical field that the present invention relates to steam power plant is a kind of " energy-efficient burning boiler technology "

Background technology:

Thermal power plant be a kind of job facilities transferring electric energy to heat energy with coal for main fuel, the generating of pushing turbine drive electrical generators is carried out with boiler develops steam vapor, because steam power plant is that consumption coal rich and influential family is called for short coal tiger, along with the development of national economy, whole nation power plant and other increase with coal unit, coal source is reduced year by year, and coal-saving measures seems particularly important for this reason.

Summary of the invention:

In order to solve the problem, the present invention's open a kind of high " effect energy-saving combustion boiler technology "

The present invention is the design formed according to the principle of oxygen furnace steel, be characterised in that adding oxygen lance in the coal pipe of torch firing boiler simultaneously combustion-supporting, flame temperature is surged, boiler gas production increases simultaneously, because flame temperature is extra-high therefore the former residuals burnt incompletely substantially all can be burnouted, the pollution level of air is reduced greatly.Save coal consumption again, particularly coal-fired steam power plant with coal rich and influential family and use the unit of boiler be transformation newly-built all can good method.

The technique effect that the present invention can reach

1, the present invention is the design formed according to the principle of oxygen furnace steel, because the raising of fire box temperature increases quantity of steam, increases gas-turbine motive force, thus reaches multiple electricity saving coal, reduces costs increase economic benefit.

2, due to the raising of the temperature of burner hearth, combustible burnouts substantially, reduces the pollutants such as NO to the discharge of air, purifies air, be conducive to the healthy of the mankind.

Accompanying drawing illustrates:

Fig. 1, be invention implement structural representation

In figure: 1, safety valve 2, boiler 3, deliver coal tube cell 4 wind, coal dust

5, oxygen hose 6, send oxygen switch

Concrete enforcement:

One, with reference to Figure of description, former leading in the pipeline that dusts of boiler is added oxygen hose and coal dust and form mixture and spray into hearth combustion.

Two, when installing oxygen hose, safety valve must be housed and guarantee safety.

Three, installing engineers and technicians' operation that must have wide experience to oxygen blast technique in oxygen lance and process on probation, can not jump the gun.

Four, oxygen lance have to pass through the product of national detection department acceptance(check) can.

Five, concrete enforcement is then determined in conjunction with actual conditions according to each factory boiler model used and size structure etc.

Finally illustrate:

More than implement only in order to illustrate the present invention and and unrestricted scheme described in the invention, those skilled in the art is to be understood that and still can modifies to the present invention or equivalent replacement and all do not depart from the technical scheme of the spirit and scope of the present invention and improvement thereof etc. and all should be recorded among right of the present invention.

Claims

1. " energy-efficient burning boiler technology " feature 1, be will add in the pulverized coal channel of former torch firing boiler oxygen lance combustion-supporting technology improve fire box temperature increase gas production.

2., because fire box temperature is very high, feature 2 decreasing pollution that residuals most for past possible trouble substantially all can be burnouted purifies air, and is of value to health.

3. due to the raising of fire box temperature, feature 3 increases boiler gas production, improves the multiple electricity of power of gas-turbine drive electrical generators.

4. owing to increasing oxygen blown factor, feature 4 burnouts all residuals, saves coal dust conveying capacity, thus reaches the effect of energy-saving and emission-reduction.

5. due to the raising of furnace temperature, feature 5 increases generating capacity, and what economize energy finally obtained is reduce cost of electricity-generating, increases economic benefit.

In sum, increase oxygen blast combustion-supporting technology, overall superiority improves fire box temperature, increases gas production, saves coal, multiple electricity, increases economic benefit, reduces cost of electricity-generating, purifies air, be beneficial to man.
