Abstract
The utility model discloses a dual-fuel energy-saving environment-friendly boiler, which comprises a boiler casing, a water inlet valve, a blowoff valve, a discharge flue, a chimney, a water level gauge, a main gas pipe, a pressure gauge and a safety valve, wherein the boiler casing, the water inlet valve, the blowoff valve, the discharge flue and the chimney are arranged on a combustion chamber, and the main gas pipe, the pressure gauge and the safety valve are arranged at the top of the boiler casing. A plurality of heat exchange pipes are arranged in the boiler casing; the lower end of each heat exchange pipe is fixedly connected with the bottom of the boiler casing and communicated with the combustion chamber; the upper portion of each heat exchange pipe is bent; the upper end of each heat exchange pipe is fixedly connected with the lateral wall of the boiler casing and communicated with the discharge flue; a combustor is arranged in the combustion chamber and communicated with a natural gas pipe; an accessory steam pipe is arranged at the top of the boiler casing; and the lower end of the accessory steam pipe is communicated with the combustor. The dual-fuel energy-saving environment-friendly boiler has the advantages that energy consumption of the boiler can be reduced remarkably and emission of harmful gas is decreased obviously as steam is used for contacting with combusting fuel to obtain water gas or mond gas for directly participating in combustion.
Description
Technical field
The utility model relates to boiler, is specifically related to a kind of energy-saving double-fuel environment-protection boiler.
Background technology
Energy savings, protection environment are the problems of developing the economy and must consider.Boiler is the common equipment in producing, living, and it makes fuel with coal, natural gas or oil, produces steam and provides thermal source for producing, living, and discharges burnt gas and flue dust simultaneously, atmosphere pollution.For many years, people seek to reduce the boiler energy consumption with working with perseverance, and the thermal efficiency is provided, and reduce the method for noxious gas emission, have obtained a lot of achievements with practical value, but can't reach the requirement of current energy-saving and environmental protection.Therefore, also need to explore new approach.
Summary of the invention
The purpose of this utility model provides a kind of energy-saving double-fuel environment-protection boiler, it partly utilizes steam to obtain water-gas or semiwater gas and participate in burning with just contacting in burnt fuel, can significantly reduce the energy consumption and the operating cost of boiler, obviously reduce discharge of harmful gases, obtain both energy-conservation, the double effects of environmental protection again.
A kind of energy-saving double-fuel environment-protection boiler described in the utility model, comprise the combustion chamber, be located at the boiler shell above the combustion chamber, be located at the water intaking valve and the blowoff valve of boiler shell lower sidewall, be located at the smokejack and the chimney of boiler shell sidewall middle and upper part, be located at the water level meter of boiler shell side wall upper part, be located at main tracheae, Pressure gauge and the safety valve at boiler shell top, it is characterized in that:
In boiler shell, be provided with many heat exchanger tubes, fixedly connected with the bottom of boiler shell in the lower end of every heat exchanger tube, and communicate with the combustion chamber, fixedly connected with the sidewall of boiler shell in the upper bend of every heat exchanger tube and end, and communicate with smokejack, many heat exchanger tubes are immersed in the water in the boiler shell.
Be provided with a burner in the combustion chamber, this burner places on the dolly and with natural gas tube and communicates, and is provided with natural gas adjusting valve on natural gas tube, enters the amount of the natural gas of burner with adjusting.
Be provided with an auxiliary steam pipe at the top of boiler shell, the lower end of this auxiliary steam pipe communicates with burner, is provided with steam control valve on auxiliary steam pipe, enters the amount of the steam of burner with adjusting.
Described a kind of energy-saving double-fuel environment-protection boiler also comprises the steam-water separator 17 that is located at boiler shell 2 internal upper parts.
Described a kind of energy-saving double-fuel environment-protection boiler also comprises manhole cover that is located at the boiler shell top and the hand hole cover that is located at the boiler shell lower sidewall.
Described a kind of energy-saving double-fuel environment-protection boiler, the wheel of its described dolly cooperates with track on being laid on burner bottom.
This boiler is fuel at the initial stage of operation with the natural gas, after boiler operatiopn is normal, the steam that produces is exported from main tracheae, for producing or/and life use, at this moment, the steam control valve of open auxiliary steam pipe, in the combustion chamber, feed steam, make it to contact and obtain water-gas or semiwater gas, and participate in burning, can regulate natural gas adjusting valve simultaneously with burned flame, reduce the input quantity of natural gas, thus the purpose that realizes saving natural gas and reduce noxious gas emission.
The utility model is compared with prior art and is had the following advantages: owing to utilized steam to obtain water-gas or semiwater gas is participated in burning directly with just contacting in burnt fuel, so, the energy consumption and the operating cost of boiler can have significantly been reduced, simultaneously, obviously reduced discharge of harmful gases, obtained both energy-conservation, the double effects of environmental protection again.
