Abstract
The utility model provides a normal -pressure water heating boiler, including furnace, grate and heat exchange water tank, the grate set up in the furnace below, the grate is one kind of inclined reciprocating grate, roll grate, traveling grate stoker, the below of grate is provided with 4 air -blowers, the air -blower is controlled by intelligent system. The utility model discloses normal -pressure water heating boiler's burner adopts inclined reciprocating grate, and grate air -blower down makes the combustion area realize the segmentation forced air supply, makes coal -firedly to burn more fully, and the smoke and dust is little, grate, the air -blower of boiler are controlled by intelligent system, and degree of automation is high, can realize the economical operation.
Description
Technical field
The utility model belongs to heating equipment field, relates to a kind of normal-pressure hot-water boiler.
Background technology
Coal-burning boiler is a kind of safety, low-cost boiler type, and normal-pressure fire coal hot-water boiler comparative maturity, is widely used, but there is the shortcomings such as burning is insufficient, flue dust is large, utilization rate of heat value is low.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provides the normal-pressure hot-water boiler that a kind of sufficient combustion, flue dust are little.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of normal-pressure hot-water boiler, comprise burner hearth (1), fire grate (2) and heat exchange water tank (3), described fire grate (2) is arranged at described burner hearth (1) below, described fire grate (2) is reciprocal grate, rolling fire grate, chain fire-gate one, the below of described fire grate (2) is provided with 4 air blasts (4), and described air blast (4) is controlled by intelligence system (5).
The beneficial effects of the utility model have:
(1) burner of the utility model boiler adopts fire grate, and in combustion, fire grate motion can promote coal-fired Thorough combustion to fire coal;
(2) the utility model boiler adopts the air supply mode that gravity-flow ventilation combines with forced air supply, and under fire grate, be provided with 4 air blasts, make combustion zone segmentation forced air supply, the air output of each section is all adjustable, and burning-out zone is gravity-flow ventilation.Only need close air blast when boiler is banked up a fire, open the gravity-flow ventilation door of burning-out zone and the gravity-flow ventilation door of crack combustion zone;
(3) fire grate of boiler, air blast control by intelligence system, and automaticity is high, can realize economical operation.
accompanying drawing illustrates:
Fig. 1 is the structural representation of the utility model normal-pressure hot-water boiler.
In figure, 1. burner hearth, 2. fire grate, 3. heat exchange water tank, 4. air blast, 5. intelligence system.
Detailed description of the invention
The technical problem solved to make the utility model, technical scheme and beneficial effect are clearly understood, below in conjunction with accompanying drawing and embodiment, are further described the utility model.Should be appreciated that embodiment described herein only for explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of normal-pressure hot-water boiler, comprise burner hearth (1), fire grate (2) and heat exchange water tank (3), described fire grate (2) is arranged at described burner hearth (1) below, described fire grate (2) is reciprocal grate, the below of described fire grate (2) is provided with 4 air blasts (4), and described air blast (4) is controlled by intelligence system (5).
The burner of the present embodiment normal-pressure hot-water boiler adopts reciprocal grate, and the air blast under fire grate makes combustion zone segmentation forced air supply, and impel fired coal combustion more abundant, flue dust is little; Simultaneously the fire grate of boiler, air blast control by intelligence system, and automaticity is high, can realize economical operation; This normal-pressure hot-water boiler can be applicable to the fields such as monomer office building, factory building heating, regional central heating and bathing domestic hot-water.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any amendment, on an equal basis replacement and improvement etc. done within spirit of the present utility model and principle, all should drop within protection domain of the present utility model.
