Steam generator

Abstract

The invention discloses a steam generator, which comprises an outer tank of which the top is provided with steam outlets, wherein a combustor, a fan which is connected with the combustor and is used for discharging smoke, a circulation pump which is connected with the combustor and is used for supplying water, a steam and water separator which is connected with the combustor and is used for generating steam, and a controller electrically connected with the combustor, the fan and the circulation pump are arranged in the outer tank; the top of the outer tank is provided with a heat recovery structure used for recycling steam conduction residual heat through raw material water; and a residual heat recovery device capable of carrying out secondary temperature rise and heating on the raw material water through the smoke of the combustor is arranged in the outer tank, heat energy generated by the combustor can be fully utilized, and in addition, a smoke discharging amount is small. The steamgenerator generates steam through the steam and water separator, steam with high pressure can be generated under a joint function of the controller, a steam pressure detector and an electric contactpressure gauge, and food can be quickly steamed and heated.

Description

Technical field: [0001] The invention relates to the field of steam generating equipment, in particular to a steam generator. Background technique: [0002] A steam generator is a device that generates hot steam through heating, and is widely used in hospitals, bathrooms, hotels, textiles, clothing, food and other industries. In the catering industry, steam generators are mostly used for steaming and heating food, so that the food can quickly heat up and become cooked. However, the common steam generators currently on the market have the following disadvantages: 1. When the hot steam is ejected from the steam discharge hole, part of the heat will be absorbed by the top plate, resulting in an excessively high temperature at the top of the steam generator, which may occur after the operator touches it. scald. 2. The internal burner will continue to generate exhaust gas during operation, which will have a great impact on the environment around the steam generator, causing the...

Problems solved by technology

However, the common steam generators currently on the market have the following disadvantages: 1. When the hot steam is ejected from the steam discharge hole, part of the heat will be absorbed by the top plate, resulting in an excessively high temperature at the top of the steam generator, which may occur after the operator touches it. scald

2. The internal burner continues to generate exhaust gas after working, which will have a great impact on the environment around the steam generator, causing the nearby temperature to continue to rise

3. Most steam generators use the method of directly heating the water boiler to generate steam. This method generates less steam and the speed of steam generation is slow, which leads to a longer time required for steaming food.
