Abstract
The invention discloses a pulverized-coal combustion hot water boiler device comprising a pulverized-coal combustion furnace and a hot water boiler which are connected with each other, wherein the pulverized-coal combustion furnace is arranged below the hot water boiler; and the pulverized-coal combustion furnace is further connected with a pulverized coal burner, so that pulverized coal is mixed with a primary air and a secondary air and injected into the pulverized-coal combustion furnace. Compared with the prior art, the pulverized-coal combustion hot water boiler device has the characteristics of coal conservation, electricity conservation, environment friendliness, simpleness in operation and the like, and can achieve excellent economic benefit and social benefit.
Description
Technical field
The present invention relates to energy-saving and emission-reduction and environmental protection field, relate in particular to a kind of coal dust firing water heater device.
Background technology
At present, water heater has been widely applied to all trades and professions as thermal source, and its combustion system mainly still is based on the traveling-grate stoker fire coal, chain furnace grate combusting device structure as shown in Figure 1.Hot-water boiler 11 device has traveling-grate stoker structure 12 to be connected with coal bunker 13 directly over chain furnace grate combusting device district 14 in the combustion zone 14, fire grate structure 12 transmission coals burn, and is combustion-supporting air blast structure 15 below the traveling-grate stoker structure 12.Traveling-grate stoker is because of its fault of construction, ature of coal required relatively stricter, and burning is abundant inadequately, coal burn-off rate less than 85%, thus caused the significant wastage of the energy, and make hot water temperature's instability of output.Coal dust furnace has been widely used in large power plant, the power station combustion furnace, but also has not been widely applied in the water heater as a kind of new combustion technology.
Summary of the invention
In order to overcome the problem of energy waste, the invention provides a kind of coal dust firing water heater device, based on the present invention, can realize economizing coal, power saving and environmental protection, and simple to operate.
A kind of coal dust firing water heater of the present invention device comprises: coal dust furnace that is connected and water heater, and described coal dust furnace is arranged at the below of described water heater; Described coal dust furnace also is connected with coal burner, is used for coal dust and primary and secondary air mixing are sprayed into coal dust furnace, heats with water heater.
Above-mentioned coal dust firing water heater device, the rear of preferred described water heater also is provided with firebreak, and described firebreak is divided into radiation area and preheating zone with described water heater.
Above-mentioned coal dust firing water heater device, the lower right of preferred described preheating zone is provided with the boiler air outlet, under the described preheating zone for being provided with dust-settling compartment.
Compared with prior art, the present invention has province's coal, power saving, environmental protection, characteristics such as simple to operate, can realize good economic benefits and social benefit.
