Control method of electric coal boiler control box

Abstract

The invention relates to a boiler control device, in particular to an electricity-coal boiler control box for a train and a control method. The electric-coal boiler control box is mainly composed of an in-train temperature sensor arranged in a compartment, a boiler water temperature sensor stretching into the a boiler wall, a liquid level sensor, a PLC, a plurality of electric heating pipes, two circulating water pumps, current sensors, indicating lamps and a power source circuit. The electric-coal boiler control box and the control method have the advantages that an electric heating pipe switch knob and a water pump control switch can be manually controlled according to needs, the number of the adopted electric heating pipes and the circulating water pumps is selected, the temperature in the compartment is controlled to be stable and comfortable, the current sensors and the indicating lamps displaying the work state of the electric heating pipes and the circulating water pumps are arranged on the electric heating pipes and the circulating water pumps respectively, a system can be maintained and repaired conveniently, the workload of train crew members is relieved to a large degree, and a comfortable and sanitary travel and work environment is provided for passengers and the crew members.

Description

technical field [0001] The invention relates to a boiler control device, in particular to a control method for a boiler control box with both electricity and coal for trains. Background technique [0002] At present, coal-fired warm water circulation and electric heating are widely used in winter heating of railway passenger cars in my country. The coal-fired warm water circulation method uses a coal-fired boiler, uses coal as fuel, and continuously heats the water in the furnace body through coal combustion, so that the hot water in the boiler and the heating pipe of the carriage is continuously circulated to release heat in the carriage through the heat sink to achieve the purpose of heating the passenger car. Purpose. The coal-fired warm water circulation method has the advantages of suitable humidity, good heat preservation, and passengers feel comfortable. However, the operators need to undergo strict training before they can work on the job. Low, serious air pollutio...

Problems solved by technology

The coal-fired warm water circulation method has the advantages of suitable humidity, good heat preservation, and passengers feel comfortable. However, the operators need to undergo strict training before they can work on the job. low, seriously pollutes the air, this heating method can no longer meet the society's requirements for reducing energy consumption and protecting the environment

The electric heating method is to install electric radiators on both sides of the passenger room, and the electric heating elements inside the electric radiators consume electric energy to release heat. The advantage is direct heating, but the air in the passenger room is dry and stale, and the heat distribution is uneven. The power supply is generally AC 220V or DC 600V. Passengers are likely to directly contact the power supply and cause electric shock. When liquid flows into the heater or the air is humid, the insulation is likely to be poor, resulting in frequent tripping of the circuit breaker and poor usability.
