Method for combusting fuel reburning low-nitrogen oxide

ActiveCN102252324AImprove the mixing effectLong reduction reaction timeCombustion apparatusLow nitrogenEvaporation
The invention discloses a method for combusting a fuel reburning low-nitrogen oxide and belongs to a clean combustion method for a coal-fired boiler. Secondary medium air is used as a powder conveying medium of a combustor on the upper layer of the main combustion area of the boiler, coal powder used as a reburning fuel is conveyed into the boiler, the secondary medium air is used as distributed air of the combustor, the secondary air of the combustor on the upper layer is reduced correspondingly, the distributed air in the reburning area is reduced correspondingly, low excess air combustion is formed, the distributed air in a hearth is not enough, and finally over fire air (OFA) complements the required air; and the mixed medium of air and fuel gas is used as the conveying medium of the coal powder of the combustor of the upper layer, and the coal powder with the conventional fineness is conveyed into the boiler from the combustor on the upper layer by using a coal mill and a powder making system and is re-burnt and denitrated, and is burnt out by OFA. The problem that the reburning fuel and the fuel gas are not mixed uniformly, the reduction time is short, and the denitration efficiency is low is solved, the original design working conditions of maximum continuous evaporation capacity of the boiler and the like are not influenced, transformation is easy to realize, and the running cost is low.

High-separation multilayer joint-extrusion shrink film

The invention discloses a high-separation multilayer joint-extrusion shrink film, which comprises an outer surface layer, a separation layer, a heat sealing layer and two bonding layers. The two bonding layers are respectively located between the separation layer and the outer surface layer and between the separation layer and the heat sealing layer, the separation layer is made of one of or a combination of two of ethylene vinyl alcohol (EVOH) resin, polyvinylidene chloride resin and modified polyamide resin, the thickness of the separation layer is 10%-45% of the total thickness, the thickness of the outer surface layer is 3%-5% of the total thickness, the thickness of the heat sealing layer is 25%-35% of the total thickness, the thickness of the bonding layers is 10%-30% of the total thickness, and the number of the separation layer is one or three. The outer surface layer of the film is made of high-melting-point resin to overcome the shortcoming that users are easy to burn during a using process of products, simultaneously oxygen and water vapor separation performance are good, the anti-puncturing effect and heat sealing strength are good, and the high-separation multilayer joint-extrusion shrink film can be suitable to vacuum shrink package of chilled pork, cheese products and seafood products.

The invention discloses a cultivation material composition for producing high-quality agaricus blazei and a manure-free rice straw raw material cultivation method. The invention is characterized in that: the cultivation material composition comprises the following raw materials in part by weight: 1,000 to 1,500 parts of rice straw, 33 to 45 parts of ammonium bicarbonate, 35 to 45 parts of calciumsuperphosphate, 35 to 40 parts of gypsum and 34 to 50 parts of lime; and the rice straw raw material cultivation method comprises: raw material preparation and processing, namely primary fermentationof windrow, mushroom house selection and disinfection, secondary fermentation of culture materials on beds in the house, inoculation and culture, earthing and fruiting management, wherein the step ofraw material processing, namely primary fermentation, also comprises special pre-piling, pile building and pile turning. The method helps to effectively solve the problem that the content of heavy metals such as cadmium in the agaricus blazei exceeds a standard. Ammonium bicarbonate is used as a nitrogen source fertilizer in the cultivation materials, so damage caused by ammonia is prevented; theprocess is simple; the management is work-saving and labor-saving; the anlages of the agaricus blazei mushrooms is uniform and the mushroom shape is desirable; the yield and quality of the agaricus blazei mushrooms are high; and the artificial cultivation scale of the agaricus blazei can be enlarged.
