Abstract

The invention discloses an efficient coal-burning and gas-burning grading and layering energy-saving steam boiler. Because a gas-producing furnace principle is adopted, and air inflows and oxygen is provided from the bottom, the utilization ratio of coal burning and gas burning is improved effectively, and temperature rises rapidly; water is supplied from top to bottom and from outside to inside, and residual heat is transferred; and simultaneously secondary air inlet and oxygen supply are adopted for the secondary burning, carbonic oxide and coke are burnt fully and effectively, so the utilization ratio of coal burning and gas burning is improved greatly, and environment pollution is reduced effectively.

Description

Efficient fuel coal combustion gas hierarchical classification energy-saving steam boiler

Technical field:

The present invention relates to a kind of efficient fuel coal fuel gas energy-saving steam boiler, especially can improve coal utilizaton rate, reduce the environmental pollution energy savings.

Background technology:

At present, known coal-fired steam boiler on the market is coal to be put into lean on the chimney draught of boiler self combustion-supporting in the boiler; The consequence one that produces like this is that carbon monoxide and coal tar can not completing combustion produce environmental pollution, the 2nd, and coal utilizaton rate is low, and the 3rd, it is slow to heat up; The 4th, no matter how much water you will use that whole water are boiled, wasted a large amount of resources and time like this, moreover boiler is a heat dump; It is again a radiator simultaneously, and utilization rate therefore coal-fired and combustion gas is low.

Summary of the invention:

For the deficiency that overcomes existing coal burning and gas burning boiler (produce environmental pollution, the coal gas utilization rate is low, slow, carbon monoxide waste heats up); The present invention provides a kind of brand-new efficient fuel coal combustion gas hierarchical classification energy-saving steam boiler; To effectively carbon monoxide and coal tar fully be burnt, effectively improve the utilization rate of coal burning and gas burning and be rapidly heated.

Technical scheme:

With boiler be divided into top, middle part, bottom and inside and outside two-layer: a producer is set in the boiler bottom; Producer is positioned at the boiler bottom center; On every side by water ring around, be to contain scuttle and activity grate below, above and what place between the quick heater is the burner noz(zle) device; Inside is inner quick heater; Quick heater is to be made up of internal layer and skin, is water between two-layer, and the middle part is several horizontal water tubes; Top is to penetrate ectonexine by several hot gas escape pipes; Water sealing (sealing water) pipe is positioned at the quick heater top center and passes from upper of furnace body and chimney, stretches out, and the steam pipe on the quick heater, water thermometer, boiled water pipe are to stretch out through the boiler centre exit; Boiler middle part is that two-layer to constitute the inside be water by inside and outside, and it is peripheral to be positioned at the boiler internal quick heater, has water level to take into account the extended centre exit of steam pipe on middle part gathering hole and the boiler quick heater, water thermometer, boiled water pipe above; The boiler internal quick heater is to connect the private water supply pipe by many root beads to be connected with the bottom, by the bottom water source is provided upwards.Upper boiler is two-layer inside and outside being to be constituted with the up-small and down-big taper shape of horizontal water tube, is positioned on the boiler middle part under the chimney, adopts bayonet socket, screw to connect maintenance between them; The boiler middle part is to be positioned on the producer of boiler bottom, is fixedly connected with screw by bayonet socket, and their joint portion is separated by with resistant to elevated temperatures heat-preservation cotton its temperature can not directly be transmitted; Hearth door is advanced coal from the middle part, again from the bottom with the oxygen supply of blower fan air intake, producing high temperature in the boiler internal combustion is that boiler is heated; When carbon monoxide and coal tar get into the burner noz(zle) device above the boiler; Be its secondary oxygen supply again, it is fully burnt, heat is provided for boiler internal produces high temperature.

The beneficial effect of the present invention's technology:

Because boiler has adopted hierarchical classification and coal-fired producer principle; From the bottom air inlet oxygen supply boiler is rapidly heated and the secondary air oxygen supply, tar and carbon monoxide is fully burnt, when waste heat through top with when spreading all around; Because what adopt is to intake with top; Supply water for the boiler internal layer through outer circulation, therefore further improved the utilization rate of coal burning and gas burning, reduced environmental pollution simultaneously.
