Evaporation 15 ton vehicle mounted type steam generator

Abstract

The invention provides a vehicular steam generator with 15 ton evaporation capacity, comprising a radiation section furnace body, a transition section furnace body and a convection section furnace body which are arranged on a trailer; the inner wall of a furnace body is applied with a wall lining which is compounded with six layers of insulation materials, wherein, the first layer of the insulation materials and the second layer of the insulation materials are general aluminum silicate fiber blankets; the third layer of the insulation materials and the fourth layer of the insulation materials are standard aluminum silicate fiber blankets; and the fifth layer of the insulation materials and the sixth layer of the insulation materials are high-purity aluminum silicate fiber blankets; adjacent insulation materials are adhered together through high-temperature resistance adhesive, a stainless steel lacing net is arranged between the fourth layer of the insulation materials and the fifth layer of the insulation materials; a plurality of stainless steel anchoring bars are alternately arranged outside the stainless steel lacing net, while a plurality of stainless steel bolts are alternately arranged inside the stainless steel lacing net. The vehicular steam generator adopts a novel insulation structure so as to reduce radiation loss and lighten weight of equipment, is capable of bearing mechanical vibration during transporting, and the rated evaporation increased remarkably to 15t / h.

Description

technical field [0001] The invention relates to thermal extraction equipment in the petroleum industry, in particular to a steam generator. Background technique [0002] The steam generator is also called steam injection boiler, which is mainly composed of three sections, three systems and three auxiliary machines. Three major sections: radiation section, convection section, and transition section; three major systems: water vapor system, combustion system, and automatic control system; three auxiliary machines: high-pressure feed water pump, burner and blower. [0003] Steam generators can be divided into two categories: fixed and vehicle-mounted. Vehicle-mounted steam generators are easy to use, can reduce the workload of oilfield ground construction, and reduce the heat loss of pipeline transportation. With the continuous deepening of heavy oil exploitation in our country, oil fields have more and more diversified requirements for steam generators. According to different...

Problems solved by technology

[0004] At present, the maximum rated evaporation of the vehicle-mounted steam generator is 11.2t / h, which is far lower than the rated evaporation of the fixed steam generator. The furnace lining for heat preservation in the vehicle-mounted steam generator is composed of heavy refractory materials, which is heavy , large thickness, limited by the weight of the trailer, the furnace body cannot be made very large, and the heavy refractory material is easy to fall off when it is vibrated during transportation. These factors limit the further enlargement of the vehicle-mounted steam generator, and further Increase rated evaporation
