The utility model discloses a kind of hot water industrial boiler, comprise the water-flow circuit be made up of drum, down-comer, upper collecting chamber, lower header and radiation heating-surface, described drum is positioned at the top of boiler, the upper end of described down-comer is connected with drum, the lower end of described down-comer is connected with lower header, described down-comer is arranged in outside coal dust hot water industrial boiler, and described radiation heating-surface is made up of the tedge be arranged in stove, and in the working medium density ratio down-comer in described tedge, the density of water is little.Hot water industrial boiler of the present utility model, adopt the coal dust hot water industrial boiler of natural circulation mode, do not need circulating pump, continuous operation is reliable and stable, saves a large amount of station services, substantially increases job stability and economic benefit.
Description
Technical field
The utility model relates to a kind of Industrial Boiler, particularly relates to a kind of hot water industrial boiler.
Background technology
Current, China's space heating is based on coal-burned industrial boiler.The call of energy-saving and emission-reduction is released in order to respond national environmental protection department, in the Re-construction planning of urban construction and old urban area, build centralized heating boiler plant, employing capacity is large, efficiency is high, pollute few large hot water boiler to replace dispersion, low, the with serious pollution miniature boiler of low capacity, efficiency is particularly important.From the angle of energy-saving and emission-reduction, the boiler development of Large Copacity high parameter is a kind of trend.
It is the grate firing boiler (chain grate boiler) of fuel that the 70MW hot water industrial boiler that China adopts at present is generally with raw coal.There is the problems such as the low energy utilization rate of efficiency is not enough, pollutant emission is larger in grate firing boiler.In this field of industrial coal powder boiler, mostly be below the 29MW coal dust hot water industrial boiler of employing, the demand that industrial coal powder boiler maximizes cannot be met.And the industrial coal powder boiler employing of existing 58MW is forced circulation mode.Above-mentioned endless form, once have a power failure suddenly, boiler circulation, by whole or local stagnation, forms partial vaporization, the security of boiler is on the hazard.So far, China adopts the 70MW large-scale coal dust industrial hot water boiler technology of natural circulation mode to be also in the blank stage in cut-off.
Facts have proved, hot water heating can save fuel 20%-30% than steam heating, and temperature stabilization, and heating quality is good.Along with energy-conserving and environment-protective become fundamental state policy being day by day rooted in the hearts of the people, simultaneously along with the development of combustion technology and green technology, the maximization of coal dust hot water industrial boiler seems very important.
Summary of the invention
The purpose of this utility model is to provide a kind of hot water industrial boiler, and it is little that its Large Copacity and natural circulation mode overcome current hot water industrial boiler capacity, once the deficiency such as threat that may exist of having a power failure suddenly.
A kind of hot water industrial boiler, comprise the water-flow circuit be made up of drum 1, down-comer 3, upper collecting chamber 2, lower header 5 and radiation heating-surface, described drum is positioned at the top of boiler, the upper end of described down-comer is connected with drum, the lower end of described down-comer is connected with lower header, described down-comer is arranged in outside coal dust hot water industrial boiler, and described radiation heating-surface is made up of the tedge 4 be arranged in stove, and in the working medium density ratio down-comer in described tedge, the density of water is little.
Described water-flow circuit comprises four independently loops, and be respectively front wall loop 6, Hou Qiang loop 7, wall loop, left side 8 and right-side wall loop 9, each loop is furnished with independently down-comer 3.
Hot water industrial boiler of the present utility model, owing to employing as above technical scheme, can carry out periodical blowdown and continuous blowdown to boiler water under operation, to ensure boiler water quality, requires not too high, greatly reduce operating cost to feed water quality.Due to the drum being equipped with water capacity larger, therefore its heat storage capacity is large, the disturbance (disturbing outward) of load and pressure is not too responsive to external world, automaticity requires relatively low, the overall discharge of boiler can be ensured simultaneously, when unexpected power-off, in boiler, the heat of vaporization of stove water is greater than the amount of stored heat in stove, ensures that stove water can not produce vaporization.The circulation resistance of heating surface does not need feed pump to overcome, therefore feed pump power consumption is less, compared with forced circulation boiler, adopt the coal dust hot water industrial boiler of natural circulation mode, do not need circulating pump, continuous operation is reliable and stable, saves a large amount of station services, substantially increases job stability and economic benefit.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of hot water industrial boiler described in the utility model embodiment 1.
Fig. 2 is the water-flow circuit schematic diagram of hot water industrial boiler described in the utility model embodiment 1.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described further.
Embodiment 1
As shown in Figure 1, a kind of hot water industrial boiler, comprise the water-flow circuit be made up of drum 1, down-comer 3, upper collecting chamber 2, lower header 5 and radiation heating-surface, described drum is positioned at the top of boiler, the upper end of described down-comer is connected with drum, and the lower end of described down-comer is connected with lower header, and described down-comer is arranged in outside coal dust hot water industrial boiler, described radiation heating-surface is made up of the tedge 4 be arranged in stove, and in the working medium density ratio down-comer in described tedge, the density of water is little.
As shown in Figure 2, in order to avoid forming complicated loop, described water-flow circuit comprises four independently loops, and be respectively front wall loop 6, Hou Qiang loop 7, wall loop, left side 8 and right-side wall loop 9, each loop is furnished with independently down-comer 3.
Owing to being all water in down-comer in hot water boiler with natural circulation and tedge, the two severe difference is very little, the effective head of Natural Circulation is less, therefore, how to ensure the safe circulation water velocity of hot water boiler with natural circulation, the face that keeps from heat because producing subcooled boiling, and causes the generation of pipe explosion accident, is Natural Circulation hot water industrial boiler important step.
Hot water industrial boiler of the present utility model, owing to employing as above technical scheme, can carry out periodical blowdown and continuous blowdown to boiler water under operation, to ensure boiler water quality, requires not too high, greatly reduce operating cost to feed water quality.Due to the drum being equipped with water capacity larger, therefore its heat storage capacity is large, the disturbance (disturbing outward) of load and pressure is not too responsive to external world, automaticity requires relatively low, the overall discharge of boiler can be ensured simultaneously, when unexpected power-off, in boiler, the heat of vaporization of stove water is greater than the amount of stored heat in stove, ensures that stove water can not produce vaporization.The circulation resistance of heating surface does not need feed pump to overcome, therefore feed pump power consumption comparatively asks little, compared with forced circulation boiler, adopt the coal dust hot water industrial boiler of natural circulation mode, do not need circulating pump, continuous operation is reliable and stable, saves a large amount of station services, substantially increases job stability and the economic benefit of hot water industrial boiler.
