Abstract

The utility model relates to a high efficiency and energy saving atmospheric boiler, which is provided with a boiler chamber, an inner boiler liner, an outer boiler liner, a water chamber and a heat exchange chamber, wherein, the boiler chamber adopts a pyramid-shaped reflection type boiler chamber, promotes coal to be decomposed through the counter radiation function of the boiler chamber, maintains temperature and pressure and obviously raises the temperature of the boiler chamber; thereby, the burnout rates of the coal and gas are high and the combustion has small pollution to environment. A transverse water pipe positioned between the walls of the inner boiler liner and the inner boiler inner forms a plate and pipe type heated surface which effectively enlarges the heat exchange area of the boiler and enhances heat utilization rate. The utility model has the advantages of small size, fast temperature elevation, high heat efficiency, adaptation to different kinds of coal and fuel saving.

Description

High efficiency energy saving atmospheric boiler

The utility model relates to a kind of boiler, particularly a kind of miniature or small atmospheric boiler.

Along with improving constantly of living standards of the people and developing rapidly of various service industries, people in being applicable to, the demand of the heating boiler of small size is increasing.Yet still do not have suitable 500M at present ²The boiler of following scope inhabitation, work, management place.For this reason, general resident uses self-control or experience stove customized, and can only replace heating boiler to heat with common tea furnace in office or management place.This class boiler ubiquity following defective: fire box temperature is low, coal and flue gas after-flame rate variance, and contaminated environment, the consumption coal is many, and the heat energy utilization rate is low, and leaving water temperature is low, and heating effect is poor.

The purpose of this utility model provides a kind of 500M of being applicable to ²Below in, small size, heat energy utilization rate height, sufficient combustion, the normal-pressure boiler of low coal consumption.

The utility model is achieved in that the structure according to common normal-pressure boiler, the utlity model has burner hearth, furnace internal-lining, furnace outside-lining, has cavity between furnace internal-lining and the furnace outside-lining in order to constitute hydroecium, the cavity that furnace internal-lining surrounds constitutes heat-exchanging chamber and gas burner, at the not good defective of prior art burner hearth combustion position, burner hearth of the present utility model has adopted the reflective burner hearth of up-small and down-big pyramid, only heat the deficiency of realization according to the intensification of the water in the prior art hydroecium by the furnace internal-lining wall of heat-exchanging chamber and coal gas combustion chamber, the utility model heat-exchanging chamber and the indoor horizontally set of gas-fired the some horizontal water tubes that are connected with hydroecium.Through adopting said structure, pyramid reflection burner hearth forms the antiradiation effect, has promoted coal-fired decomposition, fire box temperature and pressure have been kept, improved fire box temperature significantly, burning velocity has been accelerated in the raising of ignition temperature again, thereby has improved the burn-off rate of coal and flue gas.After the coal-fired fully burning of burner hearth, the heat that discharges upwards flows at heat-exchanging chamber and gas burner with flue gas, and horizontal water tube and furnace internal-lining wall are heated, and making boiler integral body be heated area significantly increases, and has improved making full use of of heat energy effectively.

The utility model has the advantages that, compare with common drinking water boiler, volume is little, heating-up time shortens more than 1/2nd, and leaving water temperature improves 30-60 ℃, and coal and flue gas burn-off rate improve more than 30%, environmental pollution is little, the thermal efficiency improves 20%-35%, and can take good air draught spontaneous manner easily, blowing naked light combustion system and blowing gas-fired mode.The utility model multi-use is widely used in family, office space and management place.

The embodiment that provides below in conjunction with accompanying drawing further specifies the utility model.

According to Fig. 1 and Fig. 4, present embodiment is provided with the reflective burner hearth 1 of up-small and down-big pyramid, is provided with porose at burner hearth 1 top or does not have blind patch 2, according to stove fire is used needs, can regulate the interior combustion position of burner hearth with cover plate 2.Be provided with the some horizontal water tubes 5 that are communicated with hydroecium 4 at heat-exchanging chamber and gas burner 3, constituted the courage wallboard formula heating surface and the horizontal water tube 5 tube wall tubular type heating surfaces of the utility model furnace internal-lining 6.In order to prevent scattering and disappearing of heat, between furnace outside-lining 7 and furnace outer wall, be provided with the thermal insulation layer 8 that insulation material constitutes.According to making needs, furnace outer wall can be made of surface plate or annular surface.The main distinction of the utility model heat supply stove and water boiler only is the hydroecium of the former hydroecium less than the latter.The size that the boiler of making different purposes only need change hydroecium gets final product.

According to Fig. 3, draw a cooking in the present embodiment heat supply stove burner hearth 1 with gas piping 9, the enough coal gas that generates can be drawn and be used to cook.Present embodiment as and cooking stove, the supporting installation of heat exchanger can constitute domestic heating, has a bath, cooking three-purpose cooker stove.The present embodiment heating boiler generally can be with 4-6 to organize every group of 16 radiators of four column types, and Large Furnace can be with 40 groups of above radiators.
