Description

APPARATUS TO AUTO CONTROL HOT WATER TEMPERATURE AND FIRE POWER OF WATER BOILER

The present invention relates to an automatic control device for hot water temperature and thermal power of a hot water boiler. In particular, a hot water boiler using briquettes, lump coal, firewood, etc. as a fuel in an industrial heating facility can be safely and automatically heated while maintaining an appropriate temperature. The present invention relates to a hot water temperature and thermal power automatic control device of a hot water boiler.

Generally, an oil boiler is used for heating in the crop cultivation house in winter, and when the room temperature rises above the temperature suitable for the growth of crops, the amount of oil is reduced to reduce the calorific value and the room temperature is low. Increasing the amount of oil supplied at the time of loss increases the calorific value, thereby maintaining the room temperature at an appropriate temperature. In this way, the oil boiler can easily control the flow of oil, so the room temperature can be freely adjusted and automatically controlled. However, as the oil cost is greatly increased, the house crop cultivation deficits become a problem. The price of silver is high, and the price is unstable, so there is always a factor of soaring, so it is very inexpensive, and it is urgently required to use a boiler which uses relatively stable firewood, lump coal, briquettes as fuel for industrial facilities heating. have.

However, when a boiler using firewood, coal briquettes, briquettes, etc. as a heat source has been conventionally used, for example, for heating a crop cultivation facility, a method in which a wind heated by the boiler's heat is blown into the room is heated. Since the heating to dry the room is unable to maintain the humidity required for the growth of the crop, the growth of pests such as mite is increased, not only the growth of the crop is slow, but also the quality deterioration, as well as circulating hot air There was a problem that the duct equipment for the expensive, and the thermal efficiency is low.

Heating a room using a hot water boiler with firewood, lump coal, briquettes, etc. will solve the problems of oil boilers and hot air heating, but such hot water boilers can regulate the flow rate like oil. There is a problem that the temperature can not be automatically adjusted because the charged fuel is burned until it is exhausted inside the boiler, and the indoor temperature is maintained at a suitable temperature to block the hot water supply to the indoor side. When the boiler and the pipe is overheated, there is a problem that can not be used because the critical pressure caused by the high pressure is formed in the pipe rupture occurs.

That is, if hundreds of briquettes are charged into a hot water boiler for heating the room and the heating is performed, if the hot water circulation in the room is blocked, the temperature of the boiler is quickly overheated. It can be dropped by automatic control, and the heating temperature can be easily adjusted automatically according to the season and climate, but the briquette boiler can't take out hundreds of briquettes once charged, so it can't prevent the overheating of the hot water boiler. Because it is difficult to automatically control the heating temperature, it was economically advantageous, but it was not used to heat indoor horticultural crops and other industrial facilities.

The present invention was devised to solve the above-mentioned conventional defects and problems, while maintaining a proper temperature by using a hot water boiler that uses briquettes, coal briquettes, firewood, etc. as fuel for indoors of industrial facilities, such as crop cultivation houses. It is to provide a hot water temperature and thermal power automatic control device of the hot water boiler that can safely and automatically heating.
