The accompanying drawing summary
With reference to the description below combining, the understanding that will improve of other aspect of the present invention and advantage, wherein:
Fig. 1 is the sketch map of simplification of the system of embodiment of the present invention.
Detailed Description Of The Invention
The present invention relates to a kind of water heater system, wherein the hot water from heat recovery system is used to heat the air-flow that leads to the air inlet of burner with humidification.Purpose is to reduce energy consumption and reduce flame temperature, thereby will reduce heating power type NOx and fuel type NOx.An advantage of the invention is before the appearance of negative effect the amount of water and the closed circuit highest level that controls to of temperature of air.
Following parameter has certain effect: there is water droplet simultaneously in the condensation of water in the air pipe line in air; Keep the O of burning
2The reduction of utilizability; With existence such as the residue of combustion of cigarette ash.
NOx product main source from such as some coal and the nitrogenous fuel of oil is the conversion of the nitrogen of fuel-bound in the combustion process to NOx.In the combustion process, the nitrogen that combines in the fuel discharges as free radical, and the final N that dissociates that forms
2Or NO.When combustion oil, fuel type NOx can account for nearly 50% of total discharging, and fuel type NOx can account for total discharging when coal combustion reaches 80%.Through the humidification combustion air, reduce changing into free N significantly
2Or the amount of the NOx of the fuel-bound of NO.
Control strategy:
The purpose of native system is to remain on maximum real standard in order to ensure the water capacity with the combustion air of coal, oil or any biomass burner air, because the steam in the combustion air has been created the condition that improves gasification.
Gasification is through thermal chemical reaction solid carbonaceous substance (coal, petroleum product or living beings) to be changed into the fuel gas that is called as synthesis gas, and fuel gas is rich in hydrogen and carbon monoxide.This process need utilizes oxidant (air, oxygen, steam or mixture) to carry out under side conditions (sub-condition).Yet, usually air and vapour mixture are used as oxidant in the industry.Then, can in gas turbine or boiler, directly light gaseous mixture.Whole process is carried out in some programs and zone:
A) pyrolysis
B) oxidation
C) gasification and hydrogenation
Pyrolytic process takes place during with solid carbonaceous substance heating (302-1292 ℉), with dispense volatiles (tar, hydrogen and carbon monoxide) and produce burning (char) under having the situation of oxygen.The loss in weight of solid matter depends on its volatile content and also depends on operating condition.
In oxide regions, some in the volatile matter of release and the following exothermic oxidation reaction (1292-3632 ℉) of burning experience:
Wherein C represents carbonaceous solids and/or burning.
When generating gasification and step of hydrogenation, spent and unburned product and steam pass charcoal bed, reaction (1472-2012 ℉) below in said charcoal bed, taking place:
(8) " methanation: heat release "
Be to notice, reversible gas phase water gas shift reaction reaches poised state very fast under the temperature of gasifier importantly, so the result is the concentration with balance carbon monoxide, carbon dioxide and hydrogen.
Purpose is to utilize the gasification air humidification to improve the integrated gasification process, thereby improves the amount and the high heat value of the synthesis gas that produces.
For process is maintained under the optimum control, monitor two parameters: the CO level of flame temperature and flue gas.Along with the moisture content increase of combustion air, flame temperature descends, and CO content rises.
Flame temperature is estimated from the flue gas temperature.The CO level is measured from flue gas.If the flue gas temperature drops to below the predetermined value, keep the limit of CO concentration simultaneously at 400PPM, this indication combustion process has received the adverse effect of the high-moisture of combustion air.
With these two output parameters of control side by side, the control system will monitor following input parameter:
1. ambient air temperature and humidity ratio.
2. flow of inlet water and temperature.Need to measure water inlet/water flow and temperature to control the level of the combustion air humidification in the evaporimeter.
3. leave the saturated combustion air temperature of evaporimeter.
When the temperature of flue air or CO content indication suboptimum fired state, the control system will change above input (the 1st to 3 point) with the reconstruction optimal combustion state.According to following priority, the instruction of control system will be based on the level of these 3 input parameters.
