Description

MAIN FEATURES

Efficient Waste Management

The BGW-N incinerator can process 20kg of solid waste in a single cycle, matching the daily waste output of a 25-person crew. This reduces operational workload by allowing simultaneous incineration of solid waste and waste oil.

Innovative Semi-Distillation Structure

Miura’s semi-distillation technology enables efficient burning of water-rich materials alongside high-heat producers like plastics. Dual access to the burner simplifies maintenance and repairs, ensuring long-term reliability.

High-Performance Air Atomizer

The waste oil burner features a specialized fan and air-atomizing burner for improved combustibility, supporting efficient vaporized incineration.

Fully Automated Combustion Control

The BGW-N incinerator automates purge, ignition, combustion, and cooling, requiring minimal operator intervention. Safety limit switches actively monitor operations, minimizing risks. For degraded waste oil, the system activates both pilot and waste oil burners for effective incineration.

Advanced Ejector System

An integrated ejector at the exhaust exit maintains negative pressure within the chamber and cools gases by mixing them with diluted air. This design protects fans from corrosive exhaust gases, extending system longevity.

Dioxin Suppression Technology

By rapidly cooling exhaust gases to 200°C or below, the BGW-N prevents the formation of harmful dioxins. This ensures safer operation and reduced environmental impact.

 

 

LLOYD’S REGISTER APPROVED

Miura introduce shipboard incinerator model “BGW-N”, complied with “CE” MARKING of ship machinery directive for EU FLAG starting May.1,1999. and “IMO” MARPOL73/78/97 ANNEX VI starting Jan.1,2000.

BGW-N series incinerate simultaneously with waste oil and solid wastes which are processed specified in IIA classII.

(MEPC244(66) ANNEX A1.4)

 

OUTLINE

This applies to all new IMO MARPOL 

In order to prevent the pollution of oceans and seas, IMO MARPOL establishes guidelines for solid and liquid waste discharged from ships.

The regulations regarding Shipboard incinerators are as follows:

Object: Any incinerator loaded on board a ship on or after 1st Jan 2000
Summary: The prohibition of Shipboard incineration of waste materials containing
PCBs, heavy metals, or similar contaminants
The incinerator must be approved by IMO MEPC244(66)
The incinerator must be designed according to MEPC244(66) standards
Conditions of Operation: MARPOL 73/78/97 ANNEX VI Regulation 16
Oxygen concentration in the combustion chamber: 6-12%
Outlet temperature of the combustion chamber: 850-1200℃
Carbon monoxide concentration in exhaust gas: not to exceed 200mg/MJ
Smoke concentration in exhaust gas: not to exceed BACHARACH 3
Weight of unburned material: not to exceed 10%
Temperature of outer wall: not to exceed 60℃
Exhaust gas is to be rapidly cooled to 350℃ or less within a space of 2.5 meters in the smokestack.
The combustion chamber is normally to be operated in a negative-pressure environment.
Requirement for residual heat: 650℃ or more (continuous charge incinerator)
It shall be 600℃ in at least 5 minutes (batch disposal incinerator)
