Abstract
The kindling briquette without sulphide and nitride exhaust consists of anthracite 5-10 wt%, brown coal 75-80 wt%, sulfur fixing agent 1-2 wt%, oxidant 5-10 wt% and pre-gelatinized starch binder the rest. The kindling briquette may be lighted with one match or using lighter. The addition of sulfur fixing agent results in no release of nitride, sulfur, phosphate and other harmful matters. It has low cost and long burning time and is safe.
Description
Technical field
The invention belongs to solid fuel, particularly a kind of is the moulded coal that ignites of the no sulphur nitrogen dispensing of major ingredient with the coal.
Background technology
Honeycomb briquette is a large amount of solid fuels that use in present Chinese rural area and small and medium-sized cities, and it ignites and adopts timber or its explosive fuel of base always, and Chinese patent has been reported a large amount of easily some combustion coals, and major part is two classes: a class is the oxidation formulation; One class is the solvent soaking type.The flammable briquette of solvent soaking type is to the requirement height of ature of coal, its defective is because solvent is volatile, produce naked light during burning, must adopt wooden composition to mix in the moulded coal just can ignite, oxidation formulation flammable briquette all is to adopt saltpetre, strontium nitrate, nitrate of baryta or other nitrate are ignition dope, the incorporation of oxygenant is all above 20%, cost is higher, in addition, because nitrate is emitted pungent oxynitride in combustion processes, all can cause damage to human body and environment, in addition, inherent sulfide discharges when burning in these flammable briquettes, also environment is caused damage.
Summary of the invention
The moulded coal that ignites that the purpose of this invention is to provide the low no sulphur nitrogen dispensing of a kind of cost.Purpose of the present invention realizes by following scheme: the moulded coal that ignites of no sulphur nitrogen dispensing comprises coal, sulphur-fixing agent, oxygenant and binding agent in its raw material;
Above-mentioned sulphur-fixing agent is a lime carbonate;
Above-mentioned oxygenant is a potassium permanganate;
Above-mentioned oxygenant is a Potcrate;
Above-mentioned each composition and weight proportion thereof are: hard coal: 5-10%, brown coal 75-85%, sulphur-fixing agent 1-2%, oxygenant 5-10%, and all the other are the pre-gelatinized starch binding agent;
The moulded coal manufacture method of igniting of above-mentioned no sulphur nitrogen dispensing is that light is worn into fine powder with each composition except that binding agent, and binding agent and water mixing are formed glue, glue is added in the said mixture material again, inserts extrusion forming in the mould after being mixed, then demoulding, oven dry.
The amount of filling of oxygenant of the present invention is controlled at below 10% (weight), just can light with a match or lighter, owing to added sulphur-fixing agent, objectionable impuritiess such as liberating nitrogen, sulphur, phosphorus not during burning, need not xyloid material in the flammable composition, greatly reduce production cost, prolonged combustion time, the process of igniting is very fast and steady, security is good.
Embodiment
Embodiment 1: raw material: pulverized anthracite (60 orders, too western coal) 10 grams; Brown coal (60 orders, Lingwu coal) 78 grams; Potassium permanganate (60 order) 10 grams; Lime carbonate: 1 gram; Starch: 1 gram, potassium permanganate and lime carbonate all are processed into less than 60 purpose powder, Alpha-starch is made into the solution of 10% (weight), put into mould after mixing above mixing of materials all, extrusion molding is finished product after the oven dry, temperature is controlled at below 200 ℃ during oven dry.
Embodiment 2: hard coal: 8 grams, brown coal: 82 grams, Potcrate: 8 grams, lime carbonate 1 gram, Alpha-starch: 1 gram, the raw material except that Alpha-starch all is processed into the fine powder about 60 orders, the glue of Alpha-starch water furnishing 10% (weight), add in the above-mentioned compound, mix and all be placed on extrusion molding in the mould, be finished product after the oven dry.
