Description
Technical field:
The utility model belongs to boiler, especially relates to hot-water boiler.
Background technology:
Present big or small heating boiler mostly partly is made up of body of heater, burner hearth and furnace wall etc., inconsiderate for heat transfer structure with the effective area size of being heated, fuel combustion is insufficient, and heat dissipates serious, fails to be fully used, smoke content is big in the flue gas, contaminated environment, in addition, general boiler volume is big, furnace wall adopts brick thorough, and installation period and furnace drying time are long.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of novel hot water boiler is provided, and volume is little, installation period and furnace drying time short; Safety, energy-saving and environmental protection.
The technical scheme that the utility model is adopted for achieving the above object is: the novel hot water boiler, bottom of furnace body is a fire grate, the fire grate below is a distribution plenum, the top is a burner hearth, the fire grate afterbody is provided with the burner hearth hermatic door, burner hearth A type is arranged, be provided with water-cooled pipe type hogging in the burner hearth, the burner hearth rear portion is provided with burning chamber and flue gas expansion chamber, the flue gas barricade is arranged between the burning chamber, and the flag form convection bank is fixed on the furnace wall and the gilled tube convection bank, flue, economizer and air preheater are formed n type furnace binding, and air preheater is communicated with exhanst gas outlet, soot blower is arranged below the exhanst gas outlet, and soot blower one end is communicated with slag notch.
Described furnace wall is fin panel casing, thermal insulation layer and decorative layer from the inside to the outside; Air preheater is the outer fin cast iron pipe of internal thread; Fire grate is provided with the vertical and horizontal air compartment.
The utility model is compared with existing hot-water boiler, have the following advantages: boiler volume is little, and the big assembly of boiler body dispatches from the factory, the on-the-spot installation soon, light boiler setting does not have brickwork builds by laying bricks or stones to shorten greatly and installs and furnace drying time, can guarantee that the boiler room makes, installs operation then then.Than the heavy boiler setting boiler erection duration in bulk, can reduce about 45 days, keep ashless running in the boiler room.Each air compartment of fire grate all is provided with horizontal bellows, guarantee that fire grate broad ways air distribution is even, the fire grate afterbody is provided with swing type burner hearth hermatic door, form high thermograde, guarantee that burnt zone is in high temperature and burns state, swing type hermatic door baffle plate stops and to leak out to burner hearth, and the drag of fire grate is far smaller than eagle iron, has increased the fire grate reliability of operation.Back-end surfaces partly adopts high-performance heat transfer components ribbed pipe type economizer and the outer fin cast iron pipe regenerative air heater of internal thread, has the heat transfer efficiency height, advantages such as the low temperature resistant burn into life-span is long, in the cast iron gilled tube screw thread is arranged, effectively strengthened heat-transfer effect, and can guarantee not dust stratification, wear-resistant, outer fin increases heating surface, makes the heated surface at the end of boiler large volume little.Adopt the mechanical ashing method, replace the defeated ash of gravity type gravity flow, reduce the body of heater height.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is A-A among Fig. 1, B-B cutaway view.
The specific embodiment:
Novel hot water boiler as shown in Figure 1 and Figure 2, put frameless for single drum is vertical, from the supporting type boiler, crossbeam type chain-grate 2 is arranged at body of heater 1 bottom, fire grate 2 has vertical and horizontal air compartment 3, and each air compartment 3 is regulated indication, and the wind pressure measurement table is arranged, can observe the air compartment blast at any time, fire grate 2 afterbodys are provided with swing type burner hearth hermatic door 4, and the temperature before the hermatic door is lower than 100 ℃ behind the hermatic door about 700～800 ℃; The burner hearth 5 that the fire grate top is arranged for the A type, burner hearth face arch 6 is a tilting, the burner hearth middle part is provided with water-cooled pipe type hogging 7, most of flame guiding stokehold under hogging will be encircleed catches fire and combustion-supporting burning in order to improvement, fraction flame guiding afterbody radiation ash bed, overheavy firing, reinforcement burn, and reduce boiler slag carbon content; The burner hearth rear portion is provided with burning chamber 8 and flue gas expansion chamber 9, in order to strengthen burning and improving dust-laying effect in the stove of combustible; Hosted-type flue gas barricade is arranged between the burning chamber 8, furnace wall 10 is fin panel casing 11, attached wall fibrofelt thermal insulation layer 12 and metal Sealing furnace plate and decorative panel decorative layer 13 from the inside to the outside, it is little to increase furnace wall sealing and volume, heat-proof quality in light weight is good, good springiness, the body of heater radiation loss is little, and the thermal expansion of body of heater is had compensation ability; Flag form convection bank 14 on the furnace wall is formed n type furnace binding with the outer fin cast iron pipe regenerative air heater 18 of gilled tube convection bank 15, flue 16, fin steel tube economizer 17 and internal thread, and flue gas was turned 90 ° centrifugal depositing dust after high-temperature flue gas entered burning chamber; Enter convection tube again, 180 ° of flue gas vertical turns, centrifugal depositing dust; Enter economizer then and connect flue, flue gas half-turn, centrifugal depositing dust; Dust-laying effect is good in the stove.The soot blower 19 of the cigarette ash at economizer, air preheater place below exhanst gas outlet.
The experiment proved that the utility model product boiler thermal output 83.4%; Boiler smoke initial ejection concentration 1679mg/m
3, smoke dust discharge concentration 71mg/m
3Blackness of exhaustion: lingemann grade＜1 grade; Sulfur dioxide emissioning concentration 776mg/m
