Description
Technical field
This utility model belongs to field of boilers, is specifically related to a kind of gas fired-boiler.
Background technology
Boiler is important energy source conversion equipment, is also major power consumer and the main source of atmospheric pollution.China's boiler is based on fire coal, and coal-burned industrial boiler recoverable amount is big, and distribution is wide, energy consumption is high, pollute weight, efficiency and Environmental capacity integral level compared with abroad also certain gap, and energy-saving and emission-reduction have a high potential.China's coal-burning boiler runs use and there is a lot of problem, and one is that technical equipment falls behind, and boiler efficiency is low, and automatic boiler control technical merit is low, is unfavorable for regulating working conditions；Two is that economic operation level is the highest, and boiler type selecting nargin is excessive, and operating load fluctuation is big, and actual operating efficiency is low；Three is that fuel matching is poor；Four is that environmental protection facility is not in place.By country, the aspect such as boiler efficiency, fume emission is proposed higher pressure standard-required, be badly in need of DZLX-XX-A II coal-burning boiler is carried out upgrading, it is achieved the purpose of energy-conserving and environment-protective.
Utility model content
For solving the problem that above technology exists, this utility model provides a kind of gas fired-boiler that DZLX-XX-A II type coal-fired boiler reform forms environmental protection and energy saving, makes full use of DZLX-XX-A II coal-burning boiler original structure and transforms.
Its technical scheme is:
A kind of gas fired-boiler, including furnace body support, burner, drum, exhanst gas outlet, economizer, burner hearth and header, described furnace body support is provided above burner hearth, the front end of burner hearth is provided with burner, the burner of burner enters inside burner hearth, and the rear end (afterbody) of drum is connected to exhanst gas outlet, and exhanst gas outlet is connected to economizer, burner hearth both sides are provided with header, are provided with water screen tube and down-comer between drum and header.
This utility model utilizes natural gas to clean fuel, to changing gas transformation carrying out coal with DZLX-XX-A II type coal-burning boiler, is the boiler effective measures that reach energy-saving and emission-reduction, comprehensively improves coal-burning boiler energy-saving Environmental Protection Level, save burning cost.
This utility model forms from DZLX-XX-A II type coal-fired boiler reform.
1, removing the fire grate of coal on former coal-burning boiler, increase furnace bottom support and refractory brickwork, remaining position body of wall is built by laying bricks or stones again；
2, by applicable combustion of natural gas structure, former coal-burning boiler burner hearth is transformed, remove boiler front arch and rear arch, remove the partition wall between coal-burning boiler burner hearth and burning chamber；
3, newly-increased configuration burner, the size of burner, quantity is by calculating apolegamy accordingly, apolegamy Full automatic gas burner is optimum, this burner collection air blast, high tension electric ignition device, air supply system, burning blowing system, self closing door, cyclelog, Flame supervision and control system, automatic leak detection system is in one, by cyclelog control, the automatic follow procedure of burner starts burning, automatically burner hearth is pre-purged, automatic ignition, flame monitors automatically, load is automatically adjusted, the functions such as combustion failure automatic blowing out warning, cyclelog also can indicate that corresponding failure cause；
4, remove former cast iron gilled tube economizer, change economizer into；
5, setting up feedwater automatic control, boiler load is automatically adjusted, high-low water alarm and extremely low water level, superelevation vapour pressure, the automatic safety device such as flame-out.
After boiler improvement, natural gas is passed through in the burner hearth of boiler, is lighted the natural gas in burner hearth, the water in heating down-pipe by Full automatic gas burner, flow in header after hot water heating, finally flow back in drum.To be combusted fully after, flue gas enters economizer from gas exit, absorbs the heat of flue gas, reduces exhaust gas temperature, reduces flue gas loss, saves fuel.

Fig. 2 is the structural representation of DZLX-XX-A II coal-burning boiler；
Wherein, 1-furnace body support, 2-burner, 3-drum, 4-gas exit, 5-economizer, 6-burner hearth, 7-header, 8-face arch, 9-fire grate, 10-coal-burning boiler burner hearth, 11-fire coal drum, 12-rear arch, 13-burning chamber, 14-coal-burning boiler header.
Detailed description of the invention
As shown in Figure 1, a kind of gas fired-boiler, including furnace body support 1, burner 2, drum 3, exhanst gas outlet 4, economizer 5, burner hearth 6 and header 7, described furnace body support 1 is provided above burner hearth 6, and the front end of burner hearth 6 is provided with burner 2, and it is internal that the burner of burner 2 enters burner hearth 6, the rear end (afterbody) of drum 3 is connected to exhanst gas outlet 4, exhanst gas outlet 4 is connected to economizer 5, and burner hearth 6 both sides are provided with header 7, are provided with water screen tube and down-comer between drum 3 and header 7.
As shown in Figure 2, this utility model is to form according to DZLX-XX-A II coal-fired boiler reform, and coal-burning boiler changes into gas fired-boiler, and major technique is exactly that combustion system changes, no matter which kind of combustion system, the required condition of burning is burning time, combustion space, sufficient air capacity.There is time enough to burn at it in furnace cavity coal to be ensured of former coal-burning boiler, allow coal fully burn at this most.Concrete measure is: remove the fire grate 9 of coal on former coal-burning boiler, increases furnace bottom support and refractory brickwork, and remaining position body of wall is built by laying bricks or stones again；By applicable combustion of natural gas structure, former coal-burning boiler burner hearth 10 is transformed, remove boiler front arch 8 and rear arch 12, remove the partition wall between coal-burning boiler burner hearth 10 and burning chamber 13；Newly-increased configuration burner 2, the size of burner 2, quantity is by calculating apolegamy accordingly, apolegamy Full automatic gas burner is optimum, this burner collection air blast, high tension electric ignition device, air supply system, burning blowing system, self closing door, cyclelog, Flame supervision and control system, automatic leak detection system is in one, by cyclelog control, the automatic follow procedure of burner starts burning, automatically burner hearth is pre-purged, automatic ignition, flame monitors automatically, load is automatically adjusted, the functions such as combustion failure automatic blowing out warning, cyclelog also can indicate that corresponding failure cause；Remove former cast iron gilled tube economizer, change economizer into；Setting up feedwater automatic control, boiler load is automatically adjusted, high-low water alarm and extremely low water level, superelevation vapour pressure,
Stop working and wait automatic safety device.
After boiler improvement, by natural gas by burner at Boiler Furnace chamber inner combustion, produce heat and inhaled by burner hearth both sides water wall surface and convection bank heating surface, water heating in pot is produced steam.Flue gas enters economizer 5 from exhanst gas outlet 4, absorbs the waste heat of flue gas, reduces exhaust gas temperature, reduces flue gas loss, saves fuel.
