Hi Abstract;

January 1992

Future coal mining systems will be able to cut from crosscut to crosscut where advances could exceed 100 ft. However, limitations arise when ventilating such mining systems. In deep advance mining, there would be no workers at the face to advance ventilation tubing or curtain manually. Traditional methods also provide no means for maintaining face ventilation after the miner backs away from the face. U.S. Bureau of Mines research is studying means to provide effective ventilation at cut depths beyond the current limit of 40 ft. Several innovative ventilation schemes are currently being considered. One such method is the use of a jet fan to ventilate a deep cut. A jet fan is simply a freestanding fan using little or no ducting to direct the ventilation flow. Jet fan testing in a 90-ft entry revealed that higher exit velocities and greater penetration depth occurred when various configurations were used to confine and direct the air flow. Additional testing also indicated that 2,200 cfm of fresh air was delivered to the face 90 ft distant when a check curtain was used to limit entrapment around the fan. Without this curtain, this quantity dropped to only 1,000 cfm. This testing indicated that a jet fan was capable of providing ventilation to a distant face area. It also highlighted potential problems, such as re-circulation at the fan and entrapment in the jet flow. Despite these potential problems, jet fans may be adequate for ventilating cuts exceeding 40 ft.

Hi Product Scope; Hydrostatic fan drive systems.

Hi Product Scope; In Brief;

Hydrostatic fan drive systems; 

Cooling systems save on energy and space; Hydrostatic fan drive systems that can assist with the cooling of engines and exhaust systems in rail vehicles.

By continuously adjusting cooling effort to match changing requirements, the systems reduce energy use compared with traditional solutions.

They also occupy up to 20 per cent less space in the engine compartment.

According to the company, hydrostatic fan drive cooling systems provide designers with a convenient and dependable way of optimising engine and combustion temperatures, which is an essential prerequisite for satisfying increasingly stringent emission requirements.

With higher exhaust gas standards such as Euro 6, Tier 4, environmental sensitivity has become more important with higher exhaust gas standards.

Radiator cooling capacity may need to rise by up to 40 per cent, resulting in size increases of 20 per cent.

Fan drives that are applied to engines and exhaust systems compensate for this and reduce noise pollution, reducing the impact on the environment.

The robust Bodas RC controller is a programmable vehicle PLC.

It ensures the fan is always operating at the right speed from when the engine is cold, to ensure minimum time in the inefficient warm up phase, to maximum speed when the engine is operating at full power.

This keeps the engine temperature and efficiency at optimum levels, irrespective of engine the speed.

The controller can be connected to the CAN bus of the engine, thus making additional sensors unnecessary.

There are options on drives, pumps and number of sensors to suit the particular vehicle and suppliers will work with individual customers to ensure the best and most economical option is chosen.

In complex applications, multiple controllers can be connected via the CAN bus to form a network.

The number of inputs and outputs can be extended quickly and economically, and safety features are integrated in the standard version to facilitate simple and reliable machine diagnostics.

Matched to the RC controllers, the Bodas software modules offer preconfigured application solutions for drive and working hydraulics.

Hi Abstract! Hi FANS AND BLOWERS FOR COMBUSTION PROCESS.

Hi INTRODUCTION

The burning of gas, oil, coal, or other combustible material requires air. When the end result of the burning is to be an efficient combustion process, in compliance with Federal and State Clean Air Act requirements, the volume of supply air must be reliably controlled. Insufficient air volume will result in wasted fuel and excessive particulate along with potentially explosive gases in the exhaust system. Too much air increases the amount of heat carried up the stack by the excess draft. Either extreme increases the cost and difficulty of controlling exhaust emissions.

Hi NATURAL AND MECHANICAL DRAFT

Air can be supplied to the combustion process by natural or mechanical draft. Natural draft simply refers to the use of a chimney or stack to induce an upward flow of air. The stack effect pulls air into the combustion chamber. The amount of airflow depends on the stack’s height and diameter, the prevailing wind velocity, and the resistance of the burner mechanism or fuel bed itself. The demand for air-cleaning apparatus on combustion systems, particularly oil and coal, has increased the overall system resistance to such an extent that natural draft alone is seldom sufficient. Mechanical draft refers to the use of fans or blowers to create airflow through the combustion area. When mechanical draft is incorporated, the chimney or stack is used primarily to direct the exhaust gases up and away where they will not be a nuisance. Because wind velocity and direction are less important, the combustion process can be much more carefully controlled. Mechanical draft is accomplished in one of two ways: when air is blown or forced into the combustion chamber it is known as forced draft; & when the air is drawn through the combustion chamber it is called induced draft. When both forced and induced draft are used, the system is termed a balanced-draft system. Generally, the fans or blowers used for induced-draft applications are larger and more expensive than those used for similar forced-draft applications. The combustion process itself

creates gases and elevated temperatures that expand the exhaust airstream, requiring fans with greater volumetric capacity than would be required on the supply side of the combustion process to supply clean, ambient air. Also, the hot exhaust serves to lower the density of the airstream, so density corrections must be applied to the fan static pressure (SP) to overcome the actual system resistance. The fact that the exhaust or flue gases are hot often requires induced-draft fans to be of a construction suitable for higher temperatures.
