Abstract
The utility model belongs to an improvement of a civil heating boiler, in particular to a special coal floor-heating boiler which comprises a boiler body provided with a water jacket. A combustion chamber is arranged above the grate and a ventilation and ash-removal chamber is arranged under the grate. A heating chamber provided with a water jacket is connected at a smoke and fire outlet arranged at the upper side of a hearth. The boiler-body water jacket and the heating-chamber water jacket are connected into a whole. A spiral pipe provided with an inlet and an outlet is arranged in the heating-chamber water jacket; the inlet and the outlet of the spiral pipe are respectively connected with the water return opening and the water inlet of a floor-heating heat supply tube. The boiler provided by the utility model not only can fully combust fuel with high heat efficiency, but also can supply stable-temperature heat and keep the heat supply tube clean, thereby lowering heat loss and operation cost.
Description
Technical field
The utility model belongs to the improvement of civil heating boiler, the special-purpose stove of particularly coal-fired floor heating.
Background technology
The floor heating technology has energy savings, and indoor cleaning can increase indoor usable floor area, and advantages such as long service life are extensive use of in the urban building building.At present, in samll cities and towns, in the dwelling construction of rural, also progressively promote the floor heating technology again.The heating furnace that the residential building floor heating in vast rural area and town and country uses is traditional water-jacket typ radiator of cooking a meal.Cook a meal the returning of floor heating pipe, the water inlet of import and export and floor heating of radiator water jacket of water-jacket typ is connected, and water pump is installed on floor heating system, pressurizes with water pump.With the water-jacket typ radiator heating floor heating system of cooking a meal, when water pump one starts, a few minutes can all extract the hot water in the furnace water jacket out, and backwater causes the furnace body temperature fluctuation big, and uneven heating is even.Because temperature is fluctuated, the fuel in the burner hearth can not remain under the higher temperature and burn, and does not reach desirable combustion efficiency, and the thermal efficiency is low.In addition, the hot water of cooking a meal in the radiator water jacket directly enters in the floor heating heating tube, iron rust that hot water in the water jacket contains and impurity are adsorbed on the floor heating heating tube inwall easily, after operation a period of time, the scale crud layer thickening that causes the heating tube inwall to adhere to easily, the influence heat radiation seriously also can result in blockage.
Summary of the invention
The purpose of this utility model is to provide a kind of coal-fired floor heating special-purpose stove, and not only full combustion of fuel is abundant, thermal efficiency height, and also heating temperature is stable, water cleaning in the heating pad pipe, and heat loss is little, and operating cost is low.
The utility model is achieved in that the special-purpose stove of a kind of coal-fired floor heating, comprise the body of heater that has water jacket, the combustion chamber is being set above fire grate, the ventilation deashing chamber is being set below fire grate, pyrotechnics exit at the burner hearth upside is connecting the heating clamber with water jacket, furnace water jacket and heating clamber water jacket are connected as a single entity, and the spiral coil that has import and outlet is being set in the heating clamber water jacket, and the import of spiral coil is connected with water inlet with the water return outlet of floor heating heating tube respectively with outlet.
During the utility model work, the water in the coal-fired furnace body water jacket of burner hearth internal combustion, the water from the pyrotechnics heating heating clamber water jacket that pyrotechnics exports out.When the water in the utility model water jacket arrives uniform temperature, start working at the water pump that the floor heating heating system is installed, water in the floor heating heating tube is circulated, the water that circulates carries out heat exchange by spiral coil and the heated hot water of water jacket that is arranged in the heating clamber water jacket, makes the hot water temperature of floor heating heating tube remain on more stable temperature range.Because water in the floor heating heating tube and the heat in the body of heater, carry out indirect heat exchange, not in body of heater, directly to absorb, so thermal loss is little in the body of heater, the interior fire coal of burner hearth is remained under the higher temperature to burn, make fuel combustion abundant, thermal efficiency height, operating cost hang down uses common heating cost.In addition, hot water in the furnace water jacket and the hot water in the floor heating heating tube are separated from each other each self-loopa.Thereby can keep the interior water cleaning of floor heating heating tube, do not have scale and dirt.The utility model not only fuel combustion is abundant, thermal efficiency height, and also heating temperature is stable, water cleaning, and heat loss is little, and operating cost is low.
Description of drawings
Accompanying drawing is the utility model sectional structure schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, the special-purpose stove of a kind of coal-fired floor heating, comprise the body of heater 2 that has water jacket, combustion chamber 3 is being set above fire grate 4, ventilation deashing chamber 5 is being set below fire grate 4, bell 1 is installed on the pot-placing hole of body of heater 2 end face settings, below body of heater 2 water jackets, water inlet 9 is being set, connecting heating clamber 7 with water jacket in the pyrotechnics exit of burner hearth 3 back upsides; Pyrotechnics exit at burner hearth 3 back upsides can also be connected with heating clamber 7 by the fireworks channel that is evenly equipped with heating pipe 6, and heating pipe 6 two ends are communicated with body of heater 2 water jackets respectively.Body of heater 2 water jackets and heating clamber 7 water jackets are connected as a single entity, and the spiral coil 8 that has import 10 and outlet 12 is being set in heating clamber 7 water jackets, and the import 10 of spiral coil is connected with water inlet with the water return outlet of floor heating heating tube respectively with outlet 12.The radical of spiral coil 8 is the 1-6 root.When the quantity of spiral coil 8 at 2 when above, the import 10 that its import arranged side by side and outlet are synthetic unified and export 12 and be connected with water inlet with the water return outlet of floor heating heating tube respectively.Top at heating clamber 7 water jackets is being provided with air bleeding valve 11 or safety valve.
