Abstract
The utility model relates to a vertical type fixed fire grate coal-burning smoke gas three backhaul pressure-bearing steam and hot water boiler, which belongs to the technical field of boiler devices. The utility model is characterized in that a horizontal water tube is disposed in the internal furnace of the boiler; a smoke-proof firebrick is fixed on the horizontal tube; three smoke-proof firebricks and a horizontal tube are fixed in order from top to bottom, thereby three smoke-proof layers are formed in the boiler. The utility model has advantages of compact structure, easy producing and convenient use.
Description
One, technical field
The utility model relates to vertical fixed grate coal-fired flue-gas three backhaul pressure-bearing steam, hot-water boiler, belongs to the boiler plant technical field.
Two, background technology
At present, (0.07MW～0.63MW), the flue gas flow of rated operating pressure in the coal-fired pressure-bearing steam of the vertical fixed grate of 0.1MPa～0.7MPa, hot-water boiler are one to two return to rated capacity at 0.1t/h～0.9t/h, the exhaust gas temperature height, the flue gas heat loss is big, boiler thermal output is low, undercapacity causes the environment temperature height.
Three, summary of the invention
Goal of the invention of the present utility model provides a kind of smoke three-pass pressure-bearing steam, hot-water boiler that addresses the above problem.
The utility model adopts following technical scheme:
Vertical fixed grate coal-fired flue-gas three backhaul pressure-bearing steam, hot-water boiler, it is characterized in that: at boiler furnace flue (6) assembling horizontal water tube (7), be fixed on the horizontal water tube (7) every cigarette refractory brick (8), the order of pressing from top to bottom fixes every cigarette refractory brick (8) and horizontal water tube (7) one by one with 3, forms three roads every smoke stratification in boiler.
Operation principle:
Boiler is in running, coal is by firing door (5), drop on the fixed grate (2), through behind the ignition combustion, make down the combustion-supporting chimney arch of accumulation of heat (4) heat temperature raising, behind high-temperature heat accumulation, make the new coal active combustion in combustion chamber (3) that adds again, thermal-flame that is produced and flue gas and boiler heating surface carry out radiation and heat convection then, under the effect of draft that boiler draft produces with at 3 under the obstruct of cigarette refractory brick (8), naturally form smoke three-pass, fully realize the exchange heat process.
3, advantage of the present utility model:
In the coal-fired pressure-bearing steam of vertical fixed grate, hot-water boiler, smoke three-pass is set, can be by sufficient exchange heat process, reach and reduce exhaust gas temperature and flue gas heat loss, improve boiler thermal output and exert oneself, realize energy-saving and cost-reducing and improve the purpose of ambient air temperature.
The utility model compact conformation is convenient to make, and result of use is very convenient.
Four, description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: the 1-base, the 2-fixed grate, the 3-combustion chamber, the combustion-supporting chimney arch of accumulation of heat under the 4-, 5-firing door, 6-boiler furnace flue, 7-horizontal water tube, 8-be every cigarette refractory brick, 9-boiler body, 10-chimney flange.
Five, the specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
During boiler furnace flue (6) assembling horizontal water tube (7), will be every cigarette refractory brick (8) pack into the earlier top of horizontal water tube (7), after horizontal water tube (7) assembling finished, to be fixed on the horizontal water tube (7) every cigarette refractory brick (8), the order of pressing from top to bottom fixes every cigarette refractory brick (8) and horizontal water tube (7) one by one with 3, horizontal water tube (7) adopts manual solid welding with boiler furnace flue (6) assembling back, after the parts assembling solid welding on the whole cooker furnace body (9), carry out the qualified back of the whole water pressure test and carry out solid welding with base (1).The combustion-supporting chimney arch of following accumulation of heat (4) adopts the mould high temperature resisting refractory concrete, and is integrated poured on the inwall of base (1).Use fire clay every cigarette refractory brick (8), adopt the mould compacting, high temperature sintering forms.
