Description

The oil field Steam-injection Boiler Burning Pulverized Coal

Technical field:

The utility model belongs to boiler, relates to the oilfield injection boiler by it.

Background technology:

At present, the fuel of oilfield injection boiler all adopts self-produced crude oil in oil field or natural gas both at home and abroad, and the operating cost height has consumed a large amount of extremely valuable crude oil or natural gases.Crude oil that consumes or natural gas (hereinafter to be referred as oil (gas)) account for about 10% of total field putput.

Summary of the invention:

The purpose of this utility model is replace oil with coal (gas), the requirement that provides a kind of oil field Steam-injection Boiler Burning Pulverized Coal can satisfy the oilfield steam injection technology, and compactness rational in infrastructure again is a fuel with the coal, fire coal is meant raw coal and moulded coal, energy-saving and environmental protection, safety.

The technical scheme that the utility model is adopted for achieving the above object is: uphole steam generator, bottom of furnace body is coal-fired fire grate, the fire grate below is a distribution plenum, the top is a burner hearth, and the burner hearth body of wall is a fin panel casing, and fire grate top, burner hearth middle part is provided with water-cooled hogging, the fire grate afterbody is provided with the burner hearth hermatic door, the burner hearth rear portion is provided with dust chamber, and economizer is equipped with on dust chamber top, and economizer exit is communicated with dust-removal and desulfurizing equipment.

Described fire grate is a traveling-grate stoker.

Described dust chamber bottom is communicated with the slagging-off water tank.

Described distribution plenum is provided with horizontal bellows.

Described fire grate afterbody burner hearth hermatic door is that fixed rotating shaft is arranged at top, and the bottom is a swing type burner hearth hermatic door.

Described burner hearth body of wall is fin panel casing, refractory concrete layer, heat insulation layer, heat-insulation layer and stove clothing decorative layer from inside to outside successively.

Described economizer is the two-stage economizer, and for body of wall cuts off, the secondary economizer exit is communicated with dust-removal and desulfurizing equipment in the middle of one-level economizer and the secondary economizer top.

The utility model is a subcritical pressure boiler direct current combustion coal chain boiler, compares with traditional both at home and abroad oil field fuel oil (gas) injection boiler, and replace oil with coal (gas) is saved a large amount of valuable oil (gas) energy fully.China is the country of many coals, oil-poor, weak breath.Oil field fuel oil (gas) injection boiler replace oil with coal (gas), oil field can obtain huge fuel price difference expense, again national strategic oil inventory are had important support effect.The utility model solves the coal combustion technology problem and the application problem of the complete replace oil with coal of uphole steam generator (gas) at home and abroad first.Prove that through actual motion the utility model traveling-grate stoker Steam-injection Boiler Burning Pulverized Coal reaches the requirement of oilfield oil recovery steam injection technology fully.Accomplish that boiler thermal output height, energy-saving and environmental protection are all up to standard effective.With certain oil field is example, injection boiler year consumes 700,000 tons of crude oil, and natural gas 3 billion cubic meters are used Steam-injection Boiler Burning Pulverized Coal instead and substituted former fuel oil (gas) boiler, 17.5 hundred million yuan of Spring Festival holidays fuel consumption conservations can additionally provide the natural gas of 700,000 tons of crude oil and 3 billion cubic meters again for country more.

Description of drawings:

Fig. 1 is the utility model structural representation.

The specific embodiment:

Oil field Steam-injection Boiler Burning Pulverized Coal as shown in Figure 1, be subcritical pressure boiler direct current chained coal fired boiler, steam pressure is 17.5MPa, vapor (steam) temperature is 355 ℃, horizontal single tube circle of fin panel casing square burner hearth and multitube circle forced circulation direct current cooker, body of heater 1 bottom is coal-fired traveling-grate stoker 2, traveling-grate stoker has vertical, horizontal air compartment 3, air compartment has adjusting, indication wind pressure measurement table, can observe wind direction, blast at any time, five road air compartments all are provided with horizontal bellows under the fire grate, can guarantee that fire grate broad ways air distribution is even.The fire grate top is square membrane type water-evaporating furnace 5, and the burner hearth body of wall is fin panel casing 17, refractory concrete layer 16, heat insulation layer 15, heat-insulation layer 14 and stove clothing decorative layer 13 from inside to outside successively.Burner hearth face arch 6 is a tilting, the burner hearth middle part is provided with arc refractory concrete water-cooled hogging 7, part flame guiding stokehold, hogging below with face arch 6 actings in conjunction, guarantees that fire coal in time catches fire, hogging 7 is with a large amount of radiant heat, radiation is in the fire grate coal seam, and what guarantee fire coal burns hogging 7 small part radiant heat all-radiant furnace end exhausting part slag blankets, make it further to burn, reduce boiler slag carbon content.Fire grate afterbody top is provided with swing type burner hearth hermatic door 4, temperature is about 700 ℃ in front of the door, temperature is about 100 ℃ behind the door, form high thermograde, guarantee coal in the timely completing combustion of burnt zone, the swing type hermatic door can reduce burner hearth and leak out, and improves boiler thermal output, reduce the fire grate resistance again, increase the fire grate reliability of operation.The burner hearth rear portion is provided with dust chamber 11, and the dust chamber bottom is communicated with slagging-off water tank 12, and the burner hearth afterbody is provided with the two-stage economizer, and for body of wall cuts off, economizer exit is communicated with dust-removal and desulfurizing equipment 10 in the middle of one-level economizer 8 and secondary economizer 9 tops.
