Description

A kind of energy-saving heating boiler
Technical field
The utility model relates to a kind of heating boiler, refer in particular to a kind of energy-conservation, can the dual-purpose heating boiler of a stove, belong to the technical field of heating boiler.
Background technology
The problem of winter heating is that people have problem to be solved for many years, and the structure of heating stove has and structure carried out improved for fuel savings also in constantly upgrading, and has and structure is carried out improved in order to increase functional effect, specifically asks for an interview following documents:
Documents 1, a kind of efficient non-pressure heating boiler is disclosed in the Chinese patent literature of the patent No. 94217766.5, has pot, burner hearth, fire grate, water inlet, delivery port, water return outlet, exhaust outlet, coal filling hole, flue, the inner wall of upper furnace is fitted with many Super-conductive conduits along circumference, hypomere is respectively in pot and burner hearth on it, hot-water line communicates in burner hearth and with pot, upper furnace and flue corresponding position are provided with a heat reflection water tank, the heat reflection water tank has water inlet pipe and outlet pipe and pot to communicate respectively, lower furnace portion is provided with upper fire-grating and lower fire grating, and a secondary coal filling hole.Solve existing nothing and pressed the low problem of the heating boiler thermal efficiency.The heating boiler of this structure is provided with two coal filling holes in order to increase the thermal efficiency in boiler, fundamentally do not solve the problem of energy savings, causes the waste of the energy to a certain extent.And what the coal filling hole of this boiler adopted is conventional design, is arranged on the sidewall middle part and the bottom of boiler, is applicable to medium-sized or large-scale boiler structure.
Documents 2, a kind of home honeycomb briquette heating boiler is disclosed in the Chinese patent literature of the patent No. 99254966.3, it comprises interlayer body of heater, water return outlet, delivery port, flue, is located at the horizontal water tube of upper of furnace body and is located at independent movably Honey-comb briquet stove in the burner hearth.This miniature boiler had both overcome the diffusing inefficient shortcoming of coal combustion of existing burning, had overcome the low shortcoming of the existing honeycomb briquette thermal efficiency again.This boiler can be provided with 2-3 burner hearth according to family expenses area size based on heating, and easy for installation, floor space is little.Can shift out stove and accessory summer, the use of cooking separately.This boiler is to be exclusively used in the active type boiler that burns coal, and is different with the boiler structure that is proposed in the utility model.
Documents 3, the patent No. is to disclose a kind of multi-functional smoke prevention and dust control boiler in 200420116236.3 the Chinese patent literature, include a body of heater, water inlet, delivery port, coal feed point, ash hole, combustion chamber, ash-pit, smokestack and the air exhauster that links to each other with smokestack, it is characterized in that the below coiling of described smokestack is serially connected with a plurality of flues, wherein the flue top of top is connected with air exhauster, be equiped with a valve therebetween, the middle part of this flue is connected with smokestack, be equiped with a valve therebetween, the flue of lowermost end is communicated with the combustion chamber; Stretch out outside the body of heater lower end of described each flue, and offer the dedusting mouth, and the left and right dedusting mouth of the flue of lowermost end place all is equiped with heater, is equiped with the dedusting flap on remaining dedusting mouth; Described dedusting flap is threaded with the dedusting mouth; This heater all parallel connection is equiped with a flue gas switching by-pass valve control.The utility model fire coal can fully burn, and offers the dedusting mouth in the bottom of each flue, so that dedusting fast, can be used for heats up water cooks, and has the feature of environmental protection.
Documents 4, the patent No. is to disclose a kind of high effective smokeless boiler in 200520078296.5 the Chinese patent literature, its major technique characteristics are fixing interting to be provided with the contact area that the resistance dirt water jacket that is connected with furnace chamber enlarges furnace chamber and burner hearth in flue, improve the utilization rate of coal, alleviated environmental pollution.The utility model is simple in structure, low cost of manufacture, resistance dirt water jacket is divided into a plurality of combustion chambers with burner hearth, flue gas can burn in process of flowing repeatedly, can make bigger dust be subjected to hindering the dirt water jacket in the process of motion and stop and can hinder on the dirt water jacket attached to following one deck, and dust removing effects is very obvious, if also have unburned flue gas further fully to burn in the smoke box chamber, flue dust is burnt cmpletely, and the thermal efficiency is very high, thereby reaches the smokeless and dust free discharging.
And, what general heating boiler all adopted now is the design of direct combustion, its deficiency is: advance air from the bottom of boiler, the comburant time that liberated heat stops in stove when burning is short, and the various flammable flue gas and the dust that produce, waste heat directly enters chimney without any processing and discharges, coal smoke is excessive, imflammable gas fail secondary utilization, energy waste, a stove one usefulness, can only burn the matchmaker, fuel is single.These defectives all are further improved.
