Definitions
- the invention relates to a method of energy recovery of waste, of the kind of those which include a waste incineration step in a furnace for the production of thermal energy, a method according to which a waste gasification is carried out at high PCI. to produce gas, and this gas is injected into the furnace combustion chamber.
- Furnaces for the implementation of these processes are designed according to the average lower heating value (average ICP) of the waste to be incinerated and according to the average flow, generally expressed in tons per hour (t / h) of waste to be treated.
- average ICP average lower heating value
- t / h average flow
- a maximum flow is determined, as well as a maximum power of the oven. When operating the machine, it must be avoided that these maximum values are exceeded, which could degrade the performance of the oven.
- the pit manager performs an empirical mix of incoming wastes to provide an "adequate mix" to the combustion furnace.
- This "adequate mix” depends on the know-how of the manager, and can be a source of errors in some cases leading to an inadequate "mix” locating the flow / power pair of the oven outside the operating zone considered normal.
- the operator will seek to operate the furnace by avoiding exceeding the maximum power expected in the construction. For this, if the waste has a relatively high PCI compared to what was taken into account during the design of the furnace, the regulation will limit the mass flow of waste introduced into the oven so as not to risk exceeding the power maximum; this way of operating reduces the capacity of the recovery unit which will not operate at its maximum flow so that the treatment time of a given quantity of waste will be greater.
- the control underestimates the ICP of the waste and makes the oven work at its maximum mass flow, the maximum power of the oven may be exceeded.
- the main purpose of the invention is to optimize the operation of an existing waste energy recovery unit by making it operate, in a controlled manner, in the vicinity of the intersection of the maximum waste stream and the maximum power of the waste. oven.

- High PCI in particular greater than 12 MJ / kg, consisting of biomass and / or wood waste, particularly wood B, to produce syngas,
- the or each connecting line for the syngas is connected to a secondary air inlet of the furnace combustion chamber.
- a unit in which the combustion furnace is provided to operate between a maximum power and a minimum power, with a waste stream comprised between a maximum flow and a minimum flow, the waste PCI being between a higher value and a lower value , is characterized in that a regulation is provided to adjust the flow of syngas injected into the oven and to operate the oven at its maximum power.
- a solenoid valve can be installed on the connecting line and be controlled by the control for adjusting the flow of syngas injected into the furnace.
- the gas generator is co-current, downflow, with feed at the top for waste high PCI, power lateral for an oxidizing gasification agent, the output of the produced syngas being located in the lower portion of the gasifier.
- the combustor may be a grid or roller oven.

- the maximum permissible flow corresponds to a vertical line E2.
- the maximum allowable power corresponds to a horizontal line P2.
- the construction of the combustion diagram is made from the data on the deposit of waste to be burned, taking into account the annual capacity and the lower heating value PCI, the number of furnaces or of furnace lines, and the power of the (or) boiler (s).
- PCI the annual capacity and the lower heating value
- PCI the number of furnaces or of furnace lines
- PCI the power of the (or) boiler
- a flux m in im um E1 is a percentage of the maximum flux, in particular 50 to 60% of the maximum flux.
- a mass overload zone Zm corresponds to a vertical band comprised between the straight line E2 of the maximum continuous permissible flow and a vertical line E3 corresponding to 1 10% of the maximum flux. Operation in this zone Zm remains acceptable but temporarily.
- a thermal overheating zone Zt corresponds to a horizontal band between the line P2 of maximum power and a line P3 corresponding to 1 1 0% of the maximum power. Operation in this zone Zt remains acceptable, but it is preferable to avoid it.
- the optimal operation corresponds to the point B located at the intersection of the straight line P2 of maximum power and the vertical E2 of maximum flow.
- the PCI waste does not exceed that defined by the line D4 iso-PCI from the origin 0 and which passes by point B.
- the operator will therefore endeavor to prepare waste mixtures corresponding to an iso-PCI line such as D5 located below D4 so as to be able to process the maximum mass flow of waste, without exceeding the power maximum permissible.
- This straight line D5 cuts the vertical E2 at the operating point B1 which corresponds to a power lower than the maximum power.

- the pipe 5 is equipped with a solenoid valve 8 controlled by a regulation R which makes it possible to adjust the flow of syngas to ensure the optimum conditions of combustion in the furnace H, which can be of any type.
- the furnace H is a grated oven on the 9th inclined; waste W to burn are introduced in the upper part of this grid, and burn down on the grid. The ashes are removed at the bottom.
- the primary combustion air is supplied by a fan 1 1 below the grid 9.
- the combustion chamber 6 extends upwardly above the grid 9 and has inputs 12 for the secondary air.
- the pipe 5 is connected to at least one secondary air inlet so that the syngas is injected at the level of this secondary air into the chamber 6, above the littering bed.
